Over the coming weeks Michael Köck, Chair of Plan G: the initiative to save the highly threatened Goodeinae family of Splitfins in Mexico, will travel around zoos, public aquaria and museums across Europe in a bid to engage stakeholders in an exciting and ambitious conservation plan. His travels will take him through Denmark, Sweden, Germany, the Czech Republic, Austria, Hungary, Switzerland, France and the United Kingdom and it is hoped the trip will inspire relevant organisations and generate vital funding to save these species from extinction.

We caught up with Michael to learn more.

Could you say a bit about your background – introduce yourself a little?

Michael: I am a 56-year-old Austrian biologist who worked as a curator in a public aquarium in Vienna for 18 years. Last year I gave up this well-paid job and started working in freshwater fish conservation in Mexico, as the Chair of a 10-year conservation plan for an endemic Mexican fish group called Splitfins (subfamily Goodeinae, family Goodeidae). If you ask me why I gave up my job to work in Mexico, I will answer because I have seen what the people in this country are capable of achieving. I was impressed by the success they were able to reach with limited resources and I wanted to be part of this movement. I have faith in this community: Mexicans are incredible when they want to arrive at something and the people I work with are passionate about succeeding in conservation. I’m here to help them where I can and to learn from them whenever I can.

What is the purpose of this European tour?

Michael: The overall aim of this European zoo tour is to encourage zoos and public aquaria to become more involved in the conservation of Mexican Goodeid fish and to create something like a Goodeid Conservation Alliance. This unique group of fish is one of the most endangered in the world: 90% of the described species are threatened with extinction according to the IUCN and are therefore already in the focus of conservation efforts by many zoos and organisations. However, we want to unite all these efforts under one umbrella, and as the projects in our Plan G portfolio follow the one plan approach, meaning they include both ex situ and in situ work and involve local communities, they are certainly of interest to many zoos and public aquaria.

What are some of the key places you’ll visit?

Michael:Certainly the big zoos in Berlin, Leipzig, Nuremberg and Munich are important places, as well as Basel and Zurich, but there are others I’m looking forward to, such as Budapest and the museum in Malmö, which already play an important role in the conservation of Goodeids, or the zoo in Pilsen with a house for endangered fish. Honestly, every place I visit will be a highlight on my tour and I’m looking forward to each and every one of them.

Why did you choose these places in particular?

Michael:I have selected zoos and public aquaria that are already contributing to the conservation of the Goodeids or Mexican freshwater fish and that I will be able to reach on my tour. There are public institutions that I have known for many years and where people I call friends work, and there are others where I only know the key people virtually, and finally there are zoos that claim to be strongly committed to conservation but have not worked with fish before. These are the most exciting ones as you never know if they are also interested in freshwater fish, but as freshwater habitats are the most threatened in the world, some zoos have broadened their focus and are open to dialogue. All in all, a mixture of good old friends and hopefully new contacts.

It’s a lot of travelling! And a lot of visiting zoos, aquaria and museums. Have you done anything like this before?

Michael: No, this is something I’ve never done before. That’s what came to mind when we launched Plan G, and with it my role of chair and ambassador. So I thought I should introduce myself and Plan G to potential new partners in this exciting conservation plan, which has the potential to raise the bar for other projects and set new standards in freshwater conservation. Every penny and cent counts for these fish, and every metre on this journey is worth it. In the end, I should have visited more than 30 zoos and public aquaria in 48 days and hopefully gained more members for the Goodeid Conservation Alliance.

What can zoos, aquaria and museums offer as key allies in conservation?

Michael:Zoos, aquaria and museums reach a large group of people. Zoo visitors, who don’t really think of fish when they think of endangered animals, are awakened and interested, and lectures in museums could reach a whole new audience. By working together with them, the circle of people we can reach with our conservation efforts expands enormously. Temporary actions in zoos to create support or raise money, or the conservation euro collected by several German zoos, contribute directly to conservation and the network between zoos strengthens such an alliance and makes it very stable. As it stands, however, it is easier to approach zoos and public aquaria than museums, although the latter probably need a slightly different approach.

Finally, what are your hopes and expectations with this tour?

Michael:It would be presumptuous to have any expectations for this tour. The budget for this year has already been spent or committed, so I’m not thinking about immediate support. In the long term, I hope that I can convince many of the places I visit how important their contribution is. Protecting freshwater fish is not just about reintroducing a species, but also about listening to the local people, trying to understand their problems, aspirations and hopes, and it involves trying to get them on board and working with them to solve their problems.

This also includes environmental education and social work. A healthy, clean lake is something that everyone wants, but that the people who live on it and from it often cannot afford. But with smart and clever ideas and the will of multiple stakeholders, we could build something like a constructed wetland that helps clean the lake’s wastewater, and if you plant it with flowers that a women’s startup can sell at markets, you are not only cleaning a lake, but you are also helping to increase the community’s wealth and promote gender equality. Conservation work starts with the people and ends with them. I hope that many of the places I visit in Europe recognise this and help us find a balance between freshwater habitat conservation and people’s needs that can serve as a model for the rest of the world.

Let’s talk about the rock threadtail

A photograph of a rock threadtail, a long black insect with very delicate wings.

For Insect Week we’re shining the spotlight on one of our finest Fantastic Freshwater insects.

Meet the rock threadtail

Perched on stones set in the rocky streams of eastern Zimbabwe is one of our most delicate fantastic freshwater species. First discovered in 2013 in Chimanimani National Park, the rock threadtail (Elattoneura lapidaria) was described in 2015, then listed as critically endangered in 2017.

This damselfly is found at whopping elevations, as high as 1500-1600m above sea level in the Chimanimani Mountains. Endemic to Eastern Zimbabwe, the species is only found in the Bundi Plain and Bundi Valley.

Damsel(fly) in distress

The rock threadtail is one of the 50 landmark species at high risk of extinction identified in SHOALs Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Like many of our Fantastic Freshwater species, threats to the rock threadtail are largely a result of degradation of their habitat – in this instance as a result of particularly prolific illegal gold mining activity.

Despite Chimanimani National Park being a protected area, more and more people are travelling to eastern Zimbabwe hoping to find gold, including the park rangers. The activity has caused great harm to the natural water sources and biodiversity of the region and poses a major threat to the future of the rock threadtail.

Panning for solutions

At this stage further research of the habitat in Chimanimani National Park is needed, in order to address activities that are threatening the rock threadtail and develop a plan for meaningful conservation action.

Let’s talk about the malabar rotala

Checking out one of our Fantastic Freshwater plant species this International Plants Appreciation Day.

We’re giving some love to our Fantastic Freshwater plants this International Plant Appreciation Day.

Just 5% of all plants live in freshwaters, but they are absolutely vital to these ecosystems – and the species that call them home – surviving and thriving.

Plants oxygenate water, reduce flood risk, support nutrient cycling, and remove pollutants. They’re really doing some heavy lifting to keep our freshwater fresh!

Meet malabar rotala

With its characteristic small pink and red flowers, malabar rotala (Rotala malabarica) is a beautiful plant native to the Kannur District in Kerala, India, from where it was described in 1990.

The species has in fact only been recorded in a total of 22 ponds, with more than half of the known population in a single pond. One pond with half the population!

The Western Ghats – home to the Denison’s barb – runs along the coast of western India. The range of mountains support a very wide range of wetland-dependent plants, and represent one of the global centres of diversity of aquatic and wetland plants.

Now the bad news

Malabar rotala is one of the 50 landmark species at high risk of extinction identified in SHOAL’s Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Wetlands are very sensitive ecosystems and rely on specific environmental conditions; any disruption of these specific conditions can pose serious threats to freshwater flora. Threats to malabar rotala include:

  • Leakage of waste and habitat destruction from mining
  • Quarrying of the laterite bedrock which hold the seasonal pools where it occurs

Herbicide pollution from nearby cashew plantations

Turning the tide

Unfortunately there are currently no conservation actions in place to protect and restore the malabar rotala.

As with other freshwater plants, more research is needed to  increase our knowledge of its ecology, threats, habitat and population trends, so that effective conservation actions can be taken.

Interview with Dr Cüneyt Kaya and Dr Münevver Oral (finding the leopard barbel)

A photograph of a woman in a white t-shirt and black trousers, next to a man in a black t-shirt and green trousers. They are smiling in front of a river on a sunny day.

On the heels of the news that 25% of freshwater fish are at risk of extinction, a team of ichthyologists in Türkiye has rediscovered hope in the shape of a carp-like, spotted fish: the leopard barbel (Luciobarbus subquincunciatus).

The species – one of SHOAL and Re:wild’s Most Wanted – was last scientifically documented in 2011. That is until last November, when Dr Cüneyt Kaya and Dr Münevver Oral’s team found the fish in the Turkish section of the Tigris River.

We got the chance to catch up with Kaya and Oral about the amazing rediscovery – including the dramatic night the fish was found – and their next challenge.

SHOAL: Congratulations on the rediscovery, how do you feel now that the news is out and what has the response been like? 

DR MÜNEVVER ORAL (MO): We’re really excited. In fact, the right word would be we are thrilled, because the leopard barbel is the second species that we found from SHOAL and Re:wild’s 10 Most Wanted Lost Fishes list. As far as we are aware, no other country has found any species and Türkiye has a 100% success rate – so in this sense we are super happy and proud.

SHOAL: Going back to the beginning, when did you start looking for the leopard barbel and how did you approach the search?

MO: We started the search operation in late October. We spent more than a week trying to bring everyone together and talking with the local authorities. Where the species distributes is almost at the border of Syria and Türkiye, and the Syrian border is where you need to be careful in terms of security.

There are also a lot of dams built on the Tigris river so we needed to come up with a strategy. The Ilısu Dam was built in 2018 and is the second biggest in Türkiye in terms of water collection capacity. We did extended and comprehensive expeditions across the surrounding cities – including Batman, Hasankeyf, Şırnak, Mardin, Siirt (Botan) – and checked pretty much every single river collection point to the Tigris river.

The leopard barbel is the second species on SHOAL and Re:wild’s Most Wanted Lost Fishes list to be rediscovered, having found the Batman River loach in Southeastern Türkiye in late 2021. The leopard barbel, a difficult second album, required an adjustment in strategy.

MO: The Batman River loach prefers much shallower rivers so it was easier to go into the river and find the species, it was mostly on us, but the leopard barbel prefers deeper water so we needed fishermen with hands-on experience.

It was a lot of work but I’m so glad that it could pay off eventually.

SHOAL: The moment the fish was found sounds very dramatic, what happened?

MO: On the 12 November we finished the third expedition which had taken more than a week in Şırnak, Cizre. Cüneyt went to an IUCN meeting in Antalya (southern Türkiye), and I came back to my faculty where we are based. Then after 3 days, on 15th November at 10.30 pm, we received this facetime call from our fisherman [Mehmet Ülkü].You should have seen our faces. I was like “What’s happening at this hour? Why is he calling me on facetime?” and he was like “I have a surprise!”.

The minute I received the news I started driving in less than 30 minutes. Cüneyt was in Antalya, the southern part of Türkiye.

DR CÜNEYT KAYA (CK): Quite far away.

MO: And if you were driving how long would that take, maybe 16 hours?

CK: No, more than that. It’s really far.

MO: So he got on the first direct flight from Antalya to Van (nearest direct flight) and drove another 6 hours to finally reach Cizre.

CK: When we got there it was almost sunset.

MO: What was thrilling was whilst we were on our way Mehmet called me again and showed me this wonderful looking, much younger smaller one. A second specimen of the leopard barbel.

CK: Amazing.

MO: That can only be described as a miracle, I don’t have any other words.

CK: On the plane I saw these photos and was like “what’s happening?”!

MO: It was quite an unforgettable experience for both of us.

SHOAL: It’s such a dramatic tale! What did it feel like when you finally saw the fish with your own eyes?

MO: Well the second fish, the young one, is quite good looking. The same thing applies to every human being and animal – as we get older we tend to get a little uglier. But the younger fish was amazing, you could see the spots easily.

CK: It was yellow-ish – like a golden-yellow – so very healthy

MO: Yeah, super handsome! One of the established ichthyologists, Dr.Jörg Freyhof saw the photos and was like “Oh my god, that’s one of the best photos ever taken of the leopard barbel”, so we were very happy.

The stunning pictures of the two specimens taken by photojournalist Metin Yoksu showcase the leopard barbel in all its spotted glory. Once done marvelling at how handsome the fish was, Kaya and Oral admit to being surprised by the fish’s quiet nature.

MO: Wild species are normally super fast and they really don’t like seeing people, but this fish – both of them – wouldn’t get scared. I think it’s in their biology that they don’t. Maybe it’s because of their predator behaviour? They tend to hunt as opposed to being hunted. They were super handsome and they were quiet. 

SHOAL: Handsome and brooding, that’s so interesting.

SHOAL: Did you feel that with the rediscovery of the Batman River loach a few years ago, you felt quite confident going into the search for the leopard barbel?

CK: Yes.

MO: We were quite confident because we kept receiving anonymous calls from the locals.

CK: In the same genus there are many species, so they’d confuse them – but sometimes the calls were correct.

MO: And it’s not only the leopard barbel on our target list, there are other species. Cüneyt is the field man, he goes at least 10 or 20 times in the year…

CK: …more…

MO: …to this and other parts of Türkiye and we always observe the habitat. We had positive signs to make us think that the leopard barbel was still alive, but we wouldn’t have any proof until the night that we found the species.

SHOAL: What are your hopes for the leopard barbel both on a local level and an international level?

MO: The biggest motivation for us is to make sure that we do everything to protect the leopard barbel. That’s why we say Cizre, but we don’t pinpoint exactly where we found the species to make sure the people won’t go and hunt for it. It’s somewhere along a 40km radius, so good luck with that!

We will be going back to Şırnak to bring all the fishermen together to help them learn what to do and what not to do. There’s some fishing gear which is forbidden which causes a lot of issues for the whole aquatic ecosystem – fish, mammals, crustaceans, everything, these are called ghost fishing. It’s easily solved, during the expedition we gave instructions to local authorities and they took super fast actions. Our fisherman [Mehmet Ülkü] will be the bridge between us, academia, and local fishermen. We are so happy to have him in our team.

Also we will be in touch with the national education department to give some seminars to teachers so they can discuss the issues and understand how to protect our biodiversity for future generations.

Every second day we speak with our fisherman [Mehmet Ülkü], and an engineer from the local fisheries and agriculture department was a graduate from our department, Rıdvan Hüsem, so they’re taking us really seriously. Hopefully we as a large team will be able to carry out as many awareness activities as possible.

From his immense knowledge of the local waterways to catching the specimen itself – not to mention keeping it happy and safe as Kaya and Oral raced across the country! – the two are very emphatic that Ülkü’s contribution was vital to the successful rediscovery.

MO: He’s the star, not us. If he didn’t trust and collaborate with us, we wouldn’t be able to achieve what we achieved. His expertise helped us a lot. He is very excited and he’s already a star in Cizre when we found the species and where he’s from.

SHOAL: On an international level, Türkiye is the only country to have a 100% hit rate for rediscovering the 10 Most Wanted Lost Fishes.

MO: Yeah! Where is the award? I want to meet Leonardo Di Caprio in person! He used to be my crush in high school, so I don’t know maybe a date or a dinner?

SHOAL: Oh definitely! Why do you think it’s so important to rediscover lost species?

MO: In the ecosystem, everything is connected. It can be finding a new species or it can be rediscovering a species, it’s always important.

If you don’t know what you have at a country level or international level, you don’t know what to protect.

SHOAL: And in the communities and organisations you’ve worked with, it must be really exciting and motivating.

MO: Oh my god you know everyone is calling, everyone is clapping. Obviously Leonardo has helped us a lot, and I’m so happy, but this is already important as it is. We know that the biodiversity crisis is increasing with global warming, so we really do need to take care of our biodiversity as much as possible. 

SHOAL: So what is next for you both, do you have another ambitious project on the horizon?

MO: That question I ask to SHOAL and Re:wild. Hey guys, do you think you will be challenging us to find another lost species perhaps?

There are already so many species that we are looking forward to finding. There are already so many species that we want to figure out their phylogenetic relationships. We’re up for any challenges! If you want to update the list feel free, we’re so up for new challenges.

Leopard barbel rediscovery press release→

On the heels of the news that 25% of freshwater fish are at risk of extinction, a team of ichthyologists in Türkiye (Turkey) has rediscovered hope in the shape of a carp-like, spotted fish — the leopard barbel (Luciobarbus subquincunciatus) — in the Turkish section of the Tigris River. The species, which was last scientifically documented in 2011, is the second species on SHOAL and Re:wild’s Most Wanted Lost Fishes list to be rediscovered. The first, the Batman River loach, was found by the same intrepid team in Southeastern Türkiye in late 2021.

“There is nothing quite like the feeling of finding that a species that has been pushed to the brink of extinction is still hanging on, despite the odds. It is even more thrilling than discovering a new species because it means that we can give a rare species a second chance. With both the Batman River loach and now the leopard barbel, we have an obligation to mobilise conservation efforts to ensure neither becomes lost again”.

The leopard barbel was once abundant, ranging from Eastern Türkiye, Eastern Syria, Iran and Iraq in the Tigris-Euphrates river system. Over the last three decades, however, fishing, pollution, habitat destruction and dam construction have pushed the species to the edge of extinction. Anecdotal evidence from local fishers suggested that the fish may still be out there, so Kaya and Münevver Oral, an assistant professor at Recep Tayyip Erdogan University enlisted their help, in addition to working with the local fisheries aquaculture department.

The team started by looking at the scientific literature about where the species had been previously found. However, those data were collected before nine dams were built in the Turkish portion of the Tigris River. The dams alter water flow regimes, and cold water that accumulates at the bottom of reservoirs is sometimes released downstream. The release of cold water drives many freshwater fish toward warmer waters, so the team had to adjust its strategy to look further downstream from the dams.

Just days after the second of two expeditions, Kaya and Oral got the video call they had hoped for from local fisherman Mehmet Ülkü: he had caught a 50-centimetre (20-inch), 2-kilogram (4.4-pound) fish with conspicuous black spots and the telltale fleshy filament that dangles from the mouths of this type of freshwater fish.

Ülkü kept the fish alive in a tank with a constant oxygen supply overnight, while Kaya took a direct flight to Van city, then drove nearly six hours to Cizre, where the species was found, while Oral drove more than 11 hours through the night to see — and help release — the fish. By the time they arrived, Ülkü had caught a second leopard barbel safely in his nets.

“We dropped everything and would have gone to the ends of the Earth to see this fish, this legend, alive in the wild. I have never seen a fish as beautiful as this. It was the realisation not only of our dream to find this lost species, but of the hope that not all is lost — we still have a chance to protect the leopard barbel and all of the other incredible freshwater species it shares its home with”.

Münevver Oral, assistant professor at Recep Tayyip Erdogan University and member of the expedition team

After Kaya and Oral took photos and measured the size and shape of the two fish, they were joined by the local Cizre fisheries aquaculture department to safely release the fish, which they described as a joyous event.

“We all have a role to play in protecting our incredible natural heritage and I am proud to have used my skills to help rediscover the leopard barbel. Safeguarding this species into the future is going to require educating other fishers and continuing to bring together scientific knowledge and local expertise.”

Kaya and Oral are planning to conduct a series of seminars for fishers and teachers to help build pride in their riverways and wildlife, using the rediscovery as a case study to protect the Tigris River and its rich biodiversity. They are also hoping to get a better understanding of how many leopard barbel might still exist and where they are still found across their historic range.

In November 2023, the International Union for Conservation of Nature released an updated assessment of freshwater fish across the planet, finding that dams and water extraction are putting 45% of all threatened freshwater fish at risk of extinction. Not only have several dams built in the Turkish portion of the Tigris River impacted the leopard barbel, but a new dam is under construction in Cizre, very close to where the two leopard barbels were found.

“Freshwater ecosystems play a tremendous role in maintaining the overall health of our planet. Addressing threats and safeguarding the biodiversity that maintains these ecosystems is critical to solving the climate and biodiversity loss crises, and essential for human wellbeing. We hope the rediscovery of the leopard barbel will serve as an inspiring catalyst for future freshwater biodiversity conservation efforts in this region.”

Safeguarding Freshwater Ecosystems: Navigating the Path to Effective Protection

Archipelago Anavilhanas, State of Amazonas, Brazil

Safeguarding Freshwater Ecosystems: Navigating the Path to Effective Protection

In brief: To protect the biodiversity and essential services provided by freshwater ecosystems worldwide, specific policies are necessary. Creative solutions that go beyond traditional protected areas are needed to effectively conserve these diverse habitats and support the communities that rely on them.

New research published in the journal Nature Sustainability finds that creative solutions which go beyond conventional protected areas are necessary to safeguard the future of our planet’s freshwater ecosystems. The paper titled “Making Global Targets Local for Freshwater Protection” dives deep into the challenges and opportunities surrounding the conservation of freshwater environments.

Freshwater Protection:

Despite freshwater’s significance as the lifeblood of our ecosystems, the protection of freshwater habitats has often lagged behind that of marine and terrestrial ecosystems, contributing to alarming biodiversity losses among freshwater species. In a step forward, during the Convention on Biological Diversity’s 15th Conference of the Parties (COP15) in December 2022, inland waters were specifically included for area-based protection in the ambitious “30×30” initiative, calling for “at least 30 per cent of terrestrial, inland water, and coastal and marine areas” to be protected by 2030. Through formally including ‘inland waters’ in the target, freshwater habitats and the need to protect them are given much more emphasis than they were previously.

While the concept of achieving 30% protection by 2030 seems promising, translating this goal into effective conservation strategies for freshwater ecosystems presents unique challenges. Unlike land-based protected areas, freshwater systems are intricately connected, extending from the atmosphere to subsurface landscapes. Watersheds play a crucial role in supporting ecological processes from local to global scales, acting as connectors from source to sea, transmitting water, sediments and nutrients. Freshwater ecosystems also play a critical role in mitigating climate change. These complex interactions demand innovative approaches to protection.

Ian Harrison, Freshwater Specialist, Conservation International, said, “Protection of freshwater is unique, with its own very particular set of challenges. We are protecting ecosystems that are providing essential resources for people – the water people need to drink, grow crops, and for industry and development. Countries need to address those critical needs, which means that protecting the ecosystems often comes second to ensuring water security. In addition, we are talking about a resource that is dynamic and flowing across the landscape. Protection of rivers and wetlands in one place can be totally compromised by things like development, pollution, water extraction just upstream. As Aaron Wolf, Professor of Geography, Oregon State University, wrote “There is no such thing as managing water for a single purpose – all water management is multi-objective and based on navigating competing interests.” That is our challenge”[1].

Redefining Conservation Measures:

Effective protection for freshwater ecosystems thus entails a shift from conventional protected area paradigms. Instead of static area-based targets, conservationists must consider dynamic, ecosystem-specific strategies. These strategies encompass a mosaic of interventions, ranging from aquatic and riparian zones to watershed conservation. Such an approach acknowledges the interconnectedness of freshwater environments and the need for adaptive, context-sensitive solutions.

Balancing Multiple Objectives:

Protecting freshwater ecosystems requires striking a delicate balance between conserving biodiversity and sustaining ecosystem services. Designing and implementing protections that cater to both goals can be challenging. For example, safeguarding a free-flowing river might protect biodiversity by preventing the construction of dams. However, the service of water provision could necessitate reservoirs. These considerations emphasise the importance of clarifying protection objectives and understanding their implications.

The Road Ahead:

Moving forward, the paper underscores the significance of grassroots efforts, involving local communities and indigenous peoples in freshwater protection initiatives. Their input ensures that conservation strategies are contextually relevant and aligned with sustainable ecosystem stewardship. Robin Abell, Durable Freshwater Protection Director, The Nature Conservancy, said, ‘‘The conservation community now recognises the importance of making protections durable. And, key to durability is the support, engagement, and leadership of the local communities who depend on and steward ecosystems. Examples of durable freshwater protection around the world show that effective protections stem from IPLC participation and leadership”.

The paper also emphasises the need for accurate mapping, effective monitoring, and interdisciplinary collaboration to bridge the gaps in our understanding of freshwater ecosystems.

While the concept of achieving 30% protection by 2030 seems promising, translating this goal into effective conservation strategies for freshwater ecosystems presents unique challenges. Unlike land-based protected areas, freshwater systems are intricately connected, extending from the atmosphere to subsurface landscapes. Watersheds play a crucial role in supporting ecological processes from local to global scales, acting as connectors from source to sea, transmitting water, sediments and nutrients. Freshwater ecosystems also play a critical role in mitigating climate change. These complex interactions demand innovative approaches to protection.

Global Targets, Local Solutions:

The heart of the matter lies in translating global protection targets into localised, effective conservation actions. The process involves identifying key biodiversity areas (KBAs) that hold special importance for freshwater ecosystems and then evaluating their potential for management and protection. This approach, when integrated with existing protected areas and other effective area-based conservation mechanisms (OECMs), can provide a comprehensive framework for freshwater conservation.

Collaboration for Success:

As the push to protect 30% of terrestrial and aquatic areas by 2030 gains momentum, it’s essential to recognise that successful freshwater protection efforts require inclusivity, transparency, and a balance of objectives. Madhu Rao, Chair, IUCN World Commission on Protected Areas, said, “Combining the conservation needs of freshwater and terrestrial ecosystems in integrated protection strategies holds great promise. Governments, civil society and non-governmental organisations, including Indigenous Peoples and local communities must collaborate to ensure the future health and resilience of our vital freshwater ecosystems”.

“Making Global Targets Local for Freshwater Protection” serves as a guiding light, illuminating the complex journey toward safeguarding the planet’s freshwater ecosystems. By embracing dynamic conservation measures, involving local communities, and fostering interdisciplinary collaboration, we can pave the way for a sustainable future where both biodiversity and human wellbeing thrive.

Let’s talk about the Nubian flapshell turtle

It’s World Turtle Day so we want to shellebrate one of our Fantastic Freshwater species!

Meet the Nubian flapshell turtle

The Nubian flapshell turtle is one of Africa’s largest freshwater turtles.

Found in fragmented pockets of habitat from West Africa to Sudan, this gentle giant hadn’t been seen in the wild for decades. That was until 2017 when it was rediscovered in South Sudan.

Meet the Nubian flapshell turtle

The Nubian flapshell turtle is one of the 50 landmark species at high risk of extinction identified in SHOAL’s Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Like many of our Fantastic Freshwater species, threats to the Nubian flapshell turtle are largely a result of degradation of their habitat. However a study published in Oryx in 2021 established a new threat, one that could push the species (with its already small population size) towards extinction.

Interviews with more than 300 local fishermen about the species revealed that four Nubian flapshell turtles captured around Mongalla, South Sudan, were sold to expatriate Chinese residents, who paid up to EUR 400 per turtle for food. The high price creates a strong incentive for the fishing communities in the area to catch these turtles and there are fears the Nubian flapshell turtle could suffer the same fate of other turtle species exploited for the Asian food market.

The species is being threatened by:

  • Habitat destruction from sand mining, damming, channelisation, and pollution
  • The species is collected for human consumption

Monitor and protect

The Nubian flapshell turtle needs urgent action. Despite the species’ conservation status being Critically Endangered, it is not currently protected or regulated under any international legislation.

The authors of the 2021 study recommend the creation of a protected area for this species. Following surveys of population status, trends, and distribution, they also advise monitoring and mitigating the potential detrimental effects that the Asian export market may have on this species.

Fish species thought extinct discovered in small Singapore swamp, many miles from where it was last seen

A photograph of the Central Catchment Nature Reserve, home to the Keli bladefin catfish, the only Critically Endangered freshwater fish species in Singapore.
  • The last time the Keli bladefin catfish (Encheloclarias kelioides) was seen was 1993, approximately 300 km from the site of this discovery.
  • The finding extends the range of the species considerably, and highlights the importance of small remnant forest fragments as harbours for biodiversity.
  • The discovery confirms the species as currently the only freshwater fish species in Singapore listed globally as Critically Endangered on the IUCN Red List.

Until recently…

…the air-breathing catfish (Encheloclarias kelioides) had only ever been seen and recorded twice: once way back in 1934, and again in 1993. With much of the species’ eastern Peninsular Malaysia peat swamp habitats having been drained to make way for palm oil plantations, the catfish was listed as Critically Endangered (Possibly Extinct) in 1996. But in August 2022, researchers were baffled when a specimen turned up in a trap set by students researching crabs in Singapore’s Nee Soon Swamp Forest. Incredibly, it was the elusive Encheloclarias kelioides, discovered for the first time many miles from where it had previously been recorded.

Dr Tan Heok Hui, a Singaporean ichthyologist based at the Lee Kong Chian Natural History Museum, Faculty of Science, National University of Singapore, was one of the researchers who confirmed the identity of this surprising discovery. He said, “Encheloclarias has never been recorded in Singapore, and Encheloclarias kelioides is a really rare species that has previously only been recorded from peat swamp habitat. Singapore doesn’t have real peat swamp – the specimen was found in more like a mature acid swamp forest – so the discovery is pretty remarkable. It has rewritten our knowledge of Encheloclarias. When it first made its way to me, I thought, you’ve got to be kidding, this has to be a practical joke!”.

The Encheloclarias kelioides individuals caught were accidental bycatch from traps that had been set by Tan Zhi Wan, Research Assistant at the Lee Kong Chian Natural History Museum and Elysia Toh, Research Associate at Yale-NUS College as part of their research into semi- terrestrial crabs. Nobody was actively looking for Encheloclarias, and it was just pure luck that they recognised them as being different from any catfish known from that region. They had no permit to take the fish from the Nee Soon reserve, but before they returned the individuals to the water, they took photos to send to the experts.

Dr Tan was one of the ichthyologists who received the photos…

…and he immediately recognised the images as being Encheloclarias. A month later, Dr Tan, Tan Zhi Wan and Elysia Toh visited the same area of the Nee Soon Swamp Forest where the individuals were previously found, set similar traps and left them overnight. When they checked the traps the next day, the fish was there. Dr Tan said, “It gave me the impression that we were really lucky”.

The discovery represents a range extension for the species, which was previously understood to be restricted to peat swamps in eastern Peninsular Malaysia and possibly central Sumatra (the specimen found there has not been confirmed as Encheloclarias kelioides) (Tan, Zhi Wan et al, 2023).

The Bebar drainage where the species was spotted…

…in 1993 is around 300 km from Nee Soon. So how did the species end up 300 km from where it was last seen three decades ago? Over many millennia, Tan said, “Southeast Asia experienced floodings and drying outs from rising and lowering of the sea level. The Gulf of Thailand actually once drained to one major river, and Singapore and part of Malaysia would have been part of that. They were once connected”.

Finding Encheloclarias kelioides in the Nee Soon Swamp Forest is significant for a number of reasons. Firstly, it proves that the species is not extinct. Secondly, this represents a range extension for the species of hundreds of kilometres. And thirdly, it helps confirm the Nee Soon Swamp Forest as an area of global conservation importance. While small, at approximately 5km 2 , it is the last remaining fragment of primary freshwater swamp forest in Singapore and is lush with biodiversity, harbouring more than half of the native freshwater fish species in Singapore, with some species being restricted only to this forest (Ho et al., 2016; Li et al., 2016; Tan et al., 2020). Furthermore, it is protected under Singapore law: with the public needing a permit to enter and no threat of development, it has become a secure refuge for wildlife.

Given that species of the genus Encheloclarias are acid-water specialists, this discovery highlights the significance of the Nee Soon Swamp Forest and the importance of conserving this habitat as a stronghold of uncommon and stenotopic freshwater fauna in Singapore (Ng & Lim, 1992; Cai et al., 2018; Clews et al., 2018;).

According to Dr. Tan…

…to ensure Encheloclarias kelioides is protected from extinction, Singapore needs to keep doing what it has been doing, i.e. keep Nee Soon swamp protected. And there should be, “Proper baseline surveys and monitoring programmes by local experts, proper and fair legislation, and enforcements if people break the laws”.

He conceded that conserving the Encheloclarias genus could be a bit more tricky: “When wetlands are protected, they are never protected for the freshwater inhabitants but for birds mostly, and enigmatic animals like orangutans. Seldom fishes, which is sad. To get funding to do these surveys is not easy, and most of the local conservationists are not really trained to recognise the fish. Also, I’ve been to protected areas where you can catch fish and eat them. You can’t catch a bird or a mammal but there are different standards with fish, which is often viewed as a cheap source of protein”.

In light of the new discovery, Dr Tan together with the rest of the team, including Associate Professor Darren Yeo of the Lee Kong Chian Natural History Museum and Department of Biological Sciences, National University of Singapore, Dr Cai Yixiong, Senior Manager at the National Biodiversity Centre, National Parks Board (NParks), Tan Zhi Wan and Elysia Toh recommend the species’ IUCN Red List assessment status to be revised to Critically Endangered and consider its national conservation status in Singapore to be Critically Endangered.

The discovery occurred a few months before…

…the planned release of an ‘The Strategic Framework to Accelerate Urgent Conservation Action for ASAP Freshwater Fishes in Southeast Asia’, a collaboration between the IUCN Species Survival Commission Asian Species Action PartnershipSHOAL, and Mandai Nature, that provides a strategic framework to accelerate urgent conservation action for the most threatened freshwater fish species in Asia. The Strategic Framework is due for release this spring.

The study on the discovery of several specimens of Encheloclarias kelioides in Nee Soon Swamp Forest was co-authored by the National University of Singapore (NUS) and NParks, which is the lead agency for greenery, biodiversity conservation, and wildlife and animal health, welfare and management in Singapore, and responsible for enhancing and managing the urban ecosystems there.

In a statement…

Mr Ryan Lee, Group Director, National Biodiversity Centre, NParks, said, “The presence of these specimens in Nee Soon Swamp Forest within the Central Catchment Nature Reserve suggests the importance of small forest fragments as habitats for biodiversity including cryptic species. The Central Catchment Nature Reserve is one of four gazetted nature reserves in Singapore, which are legally protected areas of rich biodiversity that are representative sites of key indigenous ecosystems. Hence, there are restrictions on the activities that can be carried out in these areas, as well as access to certain sites, to safeguard the native flora and fauna.

“As such, minimal change to the existing freshwater swamp conditions are possible factors that could have allowed Encheloclarias kelioides to survive. It is reasonable to expect that more freshwater fish species may be discovered here in the future.

“NParks will continue to work with researchers to better understand the abundance and distribution range of Encheloclarias kelioides in Singapore, as well as the role these native catfish play in the freshwater ecosystem. This discovery highlights the significance of Nee Soon Swamp Forest as a stronghold of uncommon and specialised freshwater fauna in Singapore. As part of our efforts under the Nature Conservation Masterplan, NParks will continue to conserve Singapore’s key habitats, through the safeguarding and strengthening of Singapore’s core biodiversity areas, including our nature reserves. In addition, we will continue to conserve more native plant and animal species. These efforts will continue to allow our native biodiversity to thrive, allowing us to achieve our vision of becoming a City in Nature”.

The Lee Kong Chian Natural History Museum is currently celebrating its eighth birthday, and Encheloclarias had been displayed in the museum as part of the anniversary celebrations.

The species does not currently have a common name. Dr Tan suggested it could be called the Keli bladefin catfish: bladefin catfish is the common name for all Encheloclarias, and in Malay, Clarias catfish are known as Ikan Keli.

Let’s talk about the Diadem lady’s mantle

A photograph of the Diadem lady’s mantle plant, green spiky leaves in a star shape.

Checking out one of our (literally) flashier Fantastic Freshwater species.

We’re giving some love to our Fantastic Freshwater plants this International Plant Appreciation Day. Plants are vital components of freshwater systems, oxygenating the water reducing flood risk, supporting nutrient cycling, and removing pollutants. They’re really doing some heavy lifting to keep our freshwater fresh!

Meet the Diadem lady’s mantle

The Diadem lady’s mantle (Alchemilla diademata) is a beautiful plant is native to Lebanon. Its regal name is inspired by the way its leaves form a crown-like shape around the stem.

The Diadem lady’s mantle has an interesting history of use in traditional medicine. Used for centuries as a natural remedy for a variety of ailments, from digestive issues to menstrual problems, some even believe the plant is anti-aging.

The plant has recognised antimicrobial properties, and is used as an effective medicine against Staphylococcus which can be associated with skin infections and food poisoning. It also appears to work as a significant repellant of silverleaf whitefly, an agricultural pest species.

Arise, threats

The Diadem lady’s mantle is one of the 50 landmark species at high risk of extinction identified in SHOAL’s Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Threats to the species are closely connected to its habitat preferences, with threats including:

  • Sandstone mining
  • Overgrazing by sheep, especially during the dry season

The Eastern Mediterranean Freshwater Assessment was concluded in 2014 and represents the first major assessment of the status of and threats to freshwater biodiversity, including plants, in the region. Although large parts of this region are semi-arid and arid in nature, it supports a diverse set of freshwater species and habitats which provide a wide variety of ecosystem services to the human population, including water, food, and income.

Heavy is the head

Unfortunately there are currently no conservation actions in place to protect and restore the Diadem lady’s mantle.

In an ideal world, the actions in place would include national regulations and ex situ conservation efforts.

Interview with Maurice Kottelat (New Species)

A photograph of Maurice Kottelat submerged in water, holding a net being passed to another man only knee deep.

“Many areas that could only be reached after days in a boat or in a helicopter 20 years ago and now crossed by highways.”

Maurice Kottelat has discovered and described hundreds of freshwater species: 471 species descriptions, to be precise, and an unknown number of discoveries, and has published exactly 400 papers and books in a remarkable career that spans five decades.

Although he has spent the majority of his career focusing on species in Southeast Asia, he literally wrote the handbook, alongside Dr. Jörg Freyhof, on European freshwater fishes and, with Dr. Tan Heok Hui, discovered the world’s smallest fish, Paedocypris progenetica.

What is it about discovering and describing species that particularly appeals to you?

MAURICE: In most cases the discovery is a by-product of surveys or other work for clients; but in these cases, I usually accept the job only if it allows travel to interesting places (i.e. where I have not been before, preferably where no other ichthyologist has been, and where I am allowed to take samples to examine and study). When it comes to non-commercial activities, I am interested in places I have not been and where I expect there will be novelties.

Discovering new species is not my primary aim; it is a nice by-product demonstrating that the selection of the area was correct, or that the money was well spent. My primary interest is faunistic and inventories, landscapes. But it is fair to say that the output is often calculated as a number of species, especially new species.

To be frank, describing is boring and repetitive. It was interesting at the beginning, to show what was being discovered. But now it is linked with administrative burden (submissions, reviews, revisions, etc. Now I prefer writing books or large papers or describing species in bulk). Obviously, there is a fair amount of ego!

Also, I write because I sort of feel an obligation to make information public, for others to use for conservation, to leave a record of what existed before the construction of dams and highways, before an influx of tourists etc. I think this is a kind of moral duty. It makes me angry to read colleagues writing about a pristine lake when their pictures show something totally different from what I saw when I visited the same lake years ago.

Can you talk through the process of going out into the field to search for fish?

MAURICE: If you mean how to find new species, it is all about the instinct to select places and habitats that have not been sampled before – rapids, waterfalls, deep swamps, anything weird that people would usually avoid – and look for small fish. In fact, you can look just about anywhere there is water, including puddles and saturated soils.

How many times have you been to the field recently?

MAURICE: In the past three years, thanks to COVID, not once. But I will hopefully go back to Laos in March. Before COVID it was about two to three times per year.

A photograph of Maurice Kottelat sitting on a rock at the edge of a lake with another man, both of them are looking in buckets.

What was a particularly memorable species discovery?

MAURICE: A trip to Laos in 1999 yielded about two new species per day for a month and a paper describing 62 new species in one shot.

At that time, the published information on the fishes of Laos was more or less restricted to the Mekong. In 1999, an environment department at the World Bank (through Tony Whitten) had a programme to translate field guides from English, French, German etc into the local languages. I was asked if I could compile these reports into a single volume to be translated into Lao. I objected because there were too many blanks on the map (areas where I had not sampled were, at that time, areas where few or no ichthyologist had ever been). I negotiated to write the book only if there was funding to fill the main gaps.

I spent one month fishing in selected river basins and ‘creamed’ the easily accessed areas. Because of the publication deadline and the need to have valid names for the species, I had to rush a paper diagnosing as many of them as possible, which ended in a paper describing 62 new species and one new genus.

The book came out in 2001 and the Lao version was distributed for free to fisheries and conservation agencies, NGOs, high schools and other places.

Before I started work on fishes of Laos, about 210 species had been recorded in the country, all in the Mekong. The 2001 book includes 480. The next edition, to be published this or next year, includes 570 named species, with about another 50 unnamed species I’ll try to add.

What sorts of places are likely to have undiscovered species living in them?

MAURICE: Habitats: headwaters, rapids, wet soil, caves, swamp forests, deep water, in fact everywhere where there is water.

Areas: Southeast Asia, Myanmar, northeast India, central Borneo, southwest Asia. New species are still being discovered in southern Europe!

Are there any places you’d particularly like to target?

MAURICE: There are still places in Laos where I have not been. I still have an interest in Borneo but local conditions (especially red tape) make it a pain. I have been to Mongolia and, despite depauperate fauna, I would like to visit again. But with age, I prefer to focus on what I know best.

A photograph of four men knee deep in water, including Maurice Kottelat, holding fishing nets.)

You’re potentially the only person in the world who has built a career flying round the world getting paid to discover and describe freshwater fish species. What was your route into that?

MAURICE: Not around the world, Asia and southern Europe are enough.

I worked in a research institution and became unhappy with several conditions and resigned.

I was quickly asked to do surveys, for conservation agencies and NGOs, then for EIAs of hydropower, mining, forestry projects. I was not paid to discover new fish species, but I took time to do real surveys and brought proof of what I reported, which leads to discoveries.

The scientific surveys were mostly without salary, though they did pay for field expenses.

When I was much younger, it was not my ambition to describe fish but to travel and see fish in their habitat.

What sorts of changes have you seen to freshwater habitats and species throughout your career?

MAURICE: Many areas that could only be reached after days in a boat or in a helicopter 20 years ago and now crossed by highways. Some habitats have been greatly reduced, e.g. peat swamps, or have disappeared.

Some species have become very rare and fish densities have become very low because of overfishing. Introduced species are more and more present. Even in protected areas, aquatic habitats are not given attention, and fish are seen as a resource or as food for waterbirds, not as species in themselves. A kilogram of introduced tilapia has more value than a kilogram of 20 small endemic species.

SHOAL released their annual report New Species 2022 on World Wildlife Day, Friday 3rd March 2023. The report details the 201 species of freshwater fish identified in 2022.
