Meet the Denison’s barb

The Denison’s barb is one of the world’s most popular home aquarium fish, and can be found in living rooms from California to Kolkata.

Their striking colours and peaceful nature have put them in high demand for both beginners and expert fishkeepers. But it’s not their popularity that has led to wild populations becoming endangered.

What threats are they facing?

Sand-mining and pollution are causing damage to the fish’s habitat in India’s Western Ghats. The species’ home is under threat.

If we don’t take urgent action to protect and restore the damaged areas, this striking fish could go extinct in the wild in just a few years.

We need your help.

What can we do to help?

With your support, SHOAL and our partners Zoo Outreach, can help bring the Denison’s barb back from the brink.

We can raise awareness with the public and government officials in India
We can train staff in five airports to recognise the species and monitor the number of fishes leaving for export
We can protect the most crucial habitats, providing security, not just for the barb, but for the many other rare and threatened fishes that live in the area

Together we can make a difference.

Every single donation will help give the species a better shot at survival. Donate today at shoalconservation.org.

This film has been created for our Save Denise’s Friends campaign, in support of the Denison’s barb. The campaign is part of SOS: Support Our SHOAL, an innovative approach to freshwater conservation led in partnership with the aquarium hobby and guidance from OATA and Practical Fishkeeping.

SOS: Support our SHOAL empowers individuals and businesses from the aquarist community who want to know how they can help ensure the futures of the species they love. We have loads of resources on our website for everyone from aquarium shops to hobbyists.

Running for species running out of time

Keep them in the running marathon fundraising

Staff member Michael Edmondstone will be running the London Marathon dressed as an overlooked and underfunded species. But which one? You decide.

by Michael Edmondstone

In early July, Victoria, Synchronicity Earth’s Head of Relationships & Operations, told me there was a London Marathon place available through the organisation, and would I like to take it? I’ve been lucky enough to run the London Marathon twice before and both times were such positive, energising experiences. Tens of thousands of runners pounding the pavement and raising money for charity, with scores of boisterous supporters cheering and clapping, creates this incredibly uplifting atmosphere. You can’t help but be swept up in the joy of it all! I took the place without thinking twice.

There was no obligation, Victoria told me, to raise funds for the charity. Somebody else was originally due to run for Synchronicity Earth but had to pull out due to unforeseen circumstances, and their place had become available without strings attached. But what an opportunity to help draw attention to overlooked and underfunded species! People dress as rhinos, pandas, trees – even the globe – to draw attention to conservation, so surely I could run as one of the species supported either by Synchronicity Earth or SHOAL.

To make it even more fun, we decided to let the public choose the species from a shortlist of three threatened species: the Critically Endangered rufous-headed hornbill, the Endangered Copan brook frog, and the Vulnerable Attenborough’s killifish.

Attenborough’s killifish

Being the SHOAL guy, it’s natural I’m hoping the killifish gets picked. Here’s why:

As visitors to this website know, the global biodiversity crisis is most pronounced in the planet’s freshwaters. Freshwater ecosystems have an extinction rate four to six times higher than marine or terrestrial environments, and there has been a staggering 84% decline in freshwater population size since 1970. One in three freshwater fish are threatened with extinction, yet they still don’t receive anywhere near the same levels of funding or attention as creatures from the land or sea. This desperately needs to change if they are to have a good shot at survival, and this campaign can help put some much needed focus on the situation.

And killifish are remarkable! Certain species live in rainy pools formed by elephants’ footprints. The leathery egg casings prevent the egg from drying out for many months or even years, and when the rains finally arrive, the fish hatch into whatever pool the rains have formed –including elephants’ footprints!

Attenborough’s killifish, named after Sir David Attenborough, is a stunning crimson and turquoise fish endemic to pools and marshes that drain into the east side of Tanzania’s Lake Victoria. It is threatened by development, agriculture and aquaculture and is a stunning symbol of how freshwater fish need much more attention if they are going to survive the many anthropogenic pressures put on them.

Rufous-headed hornbill

Of course, when I asked my Synchronicity Earth colleagues which species I should pick , their suggestions were mainly based on which animals would look most spectacular and absurd to run the London Marathon dressed as.

With their large ‘casque’ or horn making their bright red bills made even more noticeable, fire-coloured necks and glossy black plumage, the rufous-headed hornbill, or talarak, was an eye-catching choice. The species is the flagship of Synchronicity Earth’s partner the Talarak Foundation.

It is thought to be one of the rarest hornbills in the world and has already disappeared from one of the islands it was once thought to inhabit (Guimaras), and survives only now on Negros and Panay. As a Critically Endangered species, it is more vulnerable to extinction than the Attenborough’s killifish or Copan brook frog, mainly due to chronic deforestation. Only three per cent of Negros and six per cent of Panay remains forested, but that data is from 2007 so it is likely to be even less today.

However, the Talarak Foundation have been able to successfully breed rufous-headed hornbills in captivity (no easy task, due to their complex nesting requirements) which may one day lead to a release of captive-bred individuals to strengthen wild populations.

Copan brook frog

This list would not properly represent Synchronicity Earth if there was not an amphibian option. Actually, there are so many spectacular amphibian species in the Amphibian Programme, it was hard to choose!

But in the end, we have gone for a frog with dazzling ruby-red eyes and lime-green leopard print. After all, what is the point in doing this if I haven’t given myself a ridiculous costuming challenge…

Like the two other species, one of the greatest conservation challenges for the Copan brook frog is that it has a highly limited geographic range. This gem of a species lives in northeastern Guatemala and northwestern Honduras, and one of the few mountain ranges it is found on is called Sierra de Caral, where our partner Foundation for Ecodevelopment and Conservation (FUNDAECO) established an amphibian reserve, La Firmeza Amphibian Reserve.

Just like many hundreds of other amphibian species around the world, the Copan brook frog has been affected by the amphibian pandemic chytridiomycosis, caused by a fungus which targets the skin of frogs, toads, and other amphibians, and leads to their death. The other key threats are loss of habitat and water pollution, which is why the work of organisations such as FUNDAECO, in hand with local communities, to keep amphibian strongholds such as La Firmeza safe, is so important.

Time to make a decision

So what do you think? Should I run dressed as the Killifish, the Hornbill or the Frog? Each of them could have wonderful, colourful costumes that will hopefully draw plenty of attention on marathon day and help raise awareness of overlooked and underfunded species. Which one should it be? Head over to the Synchronicity Earth website to cast your vote!

Cycling for sturgeon: 11,000km across Eurasia

Matthew Spencer

Cycling for sturgeon: 11,000km across Europe. An interview with Matt Spencer

Matthew Spencer recently left his job as the UK Fisheries Outreach Officer at the Marine Stewardship Council to follow a dream he hatched during lockdown: to cycle across Eurasia to raise awareness of sturgeon declines. As the most endangered group of species on the planet, sturgeon populations have plummeted in the last century, and time is now running out to save them.

SHOAL caught up with him to learn more about his motives and ambitions for this amazing project.

11,000km is a long way! What made you take on this adventure? 

The past two years have been difficult for people everywhere around the world. During lockdown, I was stuck in a small South London flat with a large world map behind my computer. In meetings, I would look at the map, scanning for the last rivers I knew that still had sturgeon swimming in them. This slowly morphed into a deep desire to actually visit these places whilst there was still sturgeon left. And so from this, an adventure was born.

Sturgeon are the world’s most endangered group of species and if we don’t change the way we treat their home rivers, we will witness the end of many sturgeon species in our lifetimes. My project will just be a drop in the ocean for what’s needed, but if enough people contributed in some way, meaningful results can be made.

The world is changing at an ever-increasing rate and, despite the great work that’s being done to fix problems, things still look bad for the environment. The idea of cycling for sturgeon evolved from a desire to support sturgeon in whatever way I could, whilst being able to explore the world before it changes.

Tell us a bit about your personal background, and why you are focusing this adventure on sturgeon. 

When I came out of university, I found that all the jobs I was interested in asked that the candidates have a high level of prior experience – even entry level jobs. This obviously makes it really difficult to get a foot on the ladder in such a competitive sector. It was by sheer chance that I managed to gain some invaluable experience: I sent an email to Flora and Fauna International and, fortunately for me, somebody was prepared to take me on as an intern on a project looking to protect sturgeon in the Rioni River.

Sturgeon represent more to me than just species that I am fond of; they represent a first foray into conservation, and a moment where I understood what I wanted to do as a ‘career’ . They gave me an opportunity to make a mark on the world and try to make a positive difference.

My time spent chasing sturgeon in Georgia was a time of huge personal development, which opened my eyes to the human aspect of conservation and the mosaic of different cultures and communities that can exist along a river. From a village where the national language had yet to reach, to another town where poachers hid in plain sight, no two people or places were alike. This is important to bear in mind when what you are trying to achieve might impact others. The old saying goes, ‘fisheries management is people management, nothing to do with the fish’ … and I would imagine this logic applies to more than just fish.

What’s the route?

The route is based on specific rivers, meaning that it will be an unusual route that will hopefully throw me into some of the last wild places in Europe and Asia. The Garonne in France is first up, before crossing the Alps and following the River Po across Italy.

After this I will follow the Danube for several hundred miles to its Delta and cross the Black Sea to revisit old stomping grounds in the Rioni basin, before crossing Azerbaijan and catching a ferry across to Kazakhstan. I plan to finish in Tashkent after visiting the Syr Darya and conducting interviews with fishers to see if I can help with rediscovering the Syr Darya shovelnose sturgeon.

I’m excited by each of the countries, and it will be interesting to see the shifting cultural norms between them. I’m sure each of the countries will bring their own challenges, but they will be offset by the adventures there.

I have had to change the route already: I was planning on going through Ukraine, but of course that’s had to change due to the war there. I will also need to be cognisant of what it means to be a British person in some of the countries, particularly some of the ‘Stans’ – some of their economies are closely tied to the Russian economy and are suffering as a result.

What are your plans when you visit sturgeon spawning sites? 

I’ll be visiting restocking and breeding facilities, joining anti-poaching controls on the Rioni River in Georgia, and meeting experts in as many countries as I can. I hope to shine a light on the local communities, NGOs and government bodies that are helping the sturgeon in some way.

Which sturgeon-related organisations will you be meeting with along the way? 

INRAE in France, Aquaculture centres such as Storione Ticino in Italy, WWF in Romania and Bulgaria, and FFI in Georgia, all the while being supported by the World Sturgeon Conservation Society and their network along the way.

What will people’s donations help to achieve? 

I am fundraising for Fauna and Flora International’s Caucasus sturgeon programme: all money raised will go towards increasing the protection of sturgeon in the Eastern Black Sea. Funding will be used to help fund Georgian masters and PhD research projects on sturgeon, further develop the fisher-eNGO network that has been built up and which is already reaping huge rewards, and lastly to support another survey of adjacent rivers to see if sturgeon are not just limited to the Rioni.

How long do you think this adventure will take?

I started on April 6th, and plan to return in the first week of October. There is a myriad of issues ongoing globally, so I am trying to be flexible and realistic as I travel. The snows in the Central Asian highlands, and the closed roads they’ll bring about, will likely be a natural indicator of when I should be heading back home.

How can people get involved?

Glad you asked. The whole premise of this expedition is to raise awareness of sturgeon. Without knowledge of something, you are unlikely to want to protect it, so I am trying to bring the news of their sorry demise into as many people’s orbits as possible.

I am running a blog as I travel, highlighting the work being done and organisations I have met, as well as illuminating what solo adventure travel can be like – both the highs and the lows!

You can find more info on the trip and can track my progress on the expedition’s website: www.oneaveragespoke.org

Or follow me on Instagram one.average.spoke

Thanks to groups like SHOAL, I hope to make whatever impact I can and galvanise support and greater funding for sturgeon and freshwater conservation projects.

OASE become Shoal’s first corporate partner

Thorsten Muck - OASE CEO

Announcing Shoal’s first corporate partnership: OASE lead the way

Shoal is excited to announce OASE as our first significant corporate partner. OASE – one of the world’s premier indoor aquatics suppliers – have shown leadership and a real commitment to freshwater species conservation through partnering with us, and have established a precedent for how corporations can help stem the tide of freshwater extinctions.

Over the coming months, OASE’s support will broadly target Shoal’s work across five continents and in 15 countries. More specifically, it will contribute to the search for Colombia’s fat catfish, one of the Top 10 Most Wanted species in our Search for the Lost Fishes programme. An expedition team will head out to Lake Tota, northeast of Bogota, in December to start the search.

Mike Baltzer, Shoal’s executive director, said: “This is an exciting, watershed moment for freshwater species conservation. OASE is a leader and innovator in the aquarium hobby, and by partnering with Shoal, they have shown their commitment to face the challenge with us to finally tackle the freshwater species crisis so neglected and overlooked until now. We hope they will be first of many and will help create a tsunami of global support across the hobby”.

We caught up with their OASE’s CEO, Thorsten Muck, to learn more about what this partnership means to them.

Why do you see Shoal as a natural fit for a partnership with OASE?

At OASE in everything we do, we make maximum environmental responsibility and sustainability a priority.

Our products are adapted perfectly to the biology of the water, run especially energy efficiently and are manufactured in the most environmentally friendly way possible.

For example, our aquariums can be individually adapted to the natural habitats of their residents.

That’s why we’re pleased to now be an official partner of Shoal.

We believe in the importance of accelerating and intensifying action to save the most threatened fish and other freshwater species.

What do you hope OASE and SHOAL will achieve together?

Every fish species that doesn’t go extinct and every species rediscovered is a win.

We hope to assist Shoal in the best way possible with species conservation. Not only financially, but especially by drawing attention to this important mission.

OASE is sponsoring Shoal’s first Search for the Lost Fishes expedition, to search for the mysterious fat catfish in Colombia’s Lake Tota. Can you say a little about your hopes for this expedition?

Of course, we hope that the expedition will be successful and that the mysterious catfish will be found.

OASE is very proud to be able to help this exciting work to look for a remarkable fish that hasn’t been seen since the 50’s.

We hope it’s found so that the populations can be boosted and the species can be given a second chance at survival.

But above all, we hope that the expedition and the accompanying communication will bring more attention to species conservation.

OASE are a market leader in indoor aquatics, and, by partnering with SHOAL, have become a pioneer in corporate conservation of the most threatened freshwater species. As the biodiversity crisis becomes more acute globally, how do you picture corporations rising to the challenge of helping with the solutions?

As one of the world’s most successful suppliers in indoor aquatics, we feel it is OASE’s duty to support organisations like Shoal.

Shoal unites many strategic partners who fight together for the protection of species.

We believe that this kind of cooperation has a great chance of success in species conservation and therefore find Shoal particularly worthy of support.

What message do you have to other corporations thinking of getting involved in conservation?

Do it! As a company, we have a duty to make a social and ecological commitment.

Of course, we should be careful not to engage in greenwashing. Sustainability and species protection is too important not to take it seriously.

We would like to take this opportunity to thank OASE for their support, and to commend them in showing conservation leadership across the aquarium hobby sector. We are looking forward to achieving great things together for the future of the planet’s freshwater species.

Shoal sponsored freshwater fish becomes world’s second #NatureCollectible or “digital species”

darkedged splitfin NFT

The darkedged splitfin Girardinichthys multiradiatus, an endemic and Endangered fish found in Mexico, was launched as the world’s second #NatureCollectible or NFTC (non-fungible token for Conservation) at the IUCN World Conservation Congress on September 7th 2021.

It will join the Seychelles magpie robin as a new digital species collectible sold on a zero-carbon blockchain infrastructure. All funds from the sale will go to Shoal as the conservation actor for the conservation of the species. The splitfin will be part of the #NatureCollectibles portfolio that has been developed as an innovative form of revenue generation for highly threatened species that need urgent funding and conservation action.

The initiative was created by the International Union for the Conservation of Nature (IUCN)’s ‘Green List Exchange’ and the Porini Foundation, alongside Nature Seychelles. Shoal has now joined as a partner. The tokens have been minted by the Porini Foundation, a Swiss based NGO on a carbon-free blockchain. This is a major breakthrough in terms of negating the high energy consumption of prior blockchain technology. Tokens are selling from USD 20 – USD 1,000 and can be easily purchased through a dedicated mobile application. It is hoped that the initial sale of the fish will raise USD 10,000 for its conservation in Mexico.

The darkedged splitfin is restricted to a small area of Mexico, and the conservation for the species is concentrated in the beautiful mountainous Zempoala Lagoons National Park, Mexico. The splitfins – or Goodeid – fishes are one of the most threatened group of species in the world. Some are extinct in the wild, and some like the tequila splitfin have been saved from the edge of the extinction through captive breeding and release. Many of the species are confined to a few small ponds and streams in desert areas of Mexico.

All raised funds will be passed onto the Ichthyology Centre at the Universidad Autónoma del Estado de Morelos in Mexico: the leaders on the conservation of this fish and many other threatened fishes.

The head of the conservation programme, Prof. Topiltzin Contreras MacBeath, said: “The dark-edged splitfin lives in one of the most densely populated regions of the world, with about 45 million people. Its range has been contracting since the 1990s, mainly due to pollution and invasive species. Even though the lakes of Zempoala National Park are not free of human impacts, they sustain four relatively healthy populations of the darkedged splitfin, that with some support, and a bit more local involvement, could be transformed into a freshwater sanctuary that will allow its long-term conservation”.

He adds: “Funds for fish conservation are always hard to find and so we welcome any excellent innovations such as #NatureCollectibles that may provide new sources of funds for neglected but highly threatened species”.

Buyers of the darkedged splitfin will benefit by knowing that they have one of the earliest #NatureCollectibles. Not only might this become valuable, but they have also made a carbon-free contribution to conservation and helped a species from extinction.

Mike Baltzer, Shoal’s executive director, said: “We are delighted that the IUCN and Porini Foundation team has chosen a freshwater fish for this exciting innovation. We need every help we can get to raise the profile of freshwater fish and most importantly raise the funds to initiate action before we lose any more fish species”.

Shoal will be working with the development team to add more fishes to the collection and ensure that new action is launched from the funds raised.

The funds will be used to maintain a community-led monitoring programme for the fish and to inform the hundreds of thousands of tourists that visit the National Park every year about the fish.

  • Go to Collectibles > Explore collectibles
  • Pick ‘darkedged splitfin’
  • Add to cart and purchase
  • Receive email confirmation with delivery instructions (with video) on how to get it delivered to your wallet

Why is Shoal working with the IUCN/Porini Foundation #naturecollectibles?

Shoal was created to support overlooked and neglected freshwater species. The neglect that these species have suffered is due to a lack of awareness and understanding about the richness and importance of this biodiversity, leading to a lack of financial support.

Shoal is committed to inspiring a new scale of action and new sources of funding. NFTCs, developed by IUCN and partners, and based on species, places and conservation actors, has the potential to raise attention and help raise the funds that these species so desperately need. When you purchase a #NatureCollectibles token, it is both a potential investment and a donation to the conservation of a highly threatened species.

The minimum we hope to raise for the darkedged splitfin is USD 10,000. This will make a significant impact for the species.
