Recent research has shown that sawfishes continue to be landed by fishers in Bangladesh. This presents a unique opportunity – to develop educational and awareness-raising tools to reach fishing communities in Bangladesh, and highlight that they can become stewards of one of the last remaining populations of largetooth sawfish in the world. This project aims to develop a short, educational film highlighting the critical status of sawfishes globally and the unique opportunity that the people of Bangladesh have to protect these unique animals. The film will be an important tool in engaging and involving communities in future conservation efforts.
Outside of sawfish strongholds in Australia and Florida, USA, the majority of sawfish populations are rapidly diminishing or have already become locally extinct. Sawfish conservation efforts in low-income countries have been few, and have often come too late. The importance of this project lies not only in protecting sawfishes in another part of the world, but also in developing a blueprint for effective and meaningful sawfish conservation actions in low-income countries, where legislation is often ineffective. Incorporating local culture, involving communities and other local and regional stakeholders, creativity and effective communication will be essential!
Sawfishes are one of the most highly endangered families of sharks and rays globally. In recent decades, populations have declined dramatically and sawfishes are now extinct from many countries where previously they were found in abundance. However, sawfishes are still caught regularly by Indian and Bangladeshi fishers in the Bay of Bengal. In a recent study, Alifa Haque and I found that at least 25 sawfishes were landed at fisheries landings sites in Bangladesh over a 14- month period. This suggests that relative to many other parts of the world, sawfishes are still relatively numerous in this region.
Although the bycatch of sawfishes in Bangladesh has been known for some time, no targeted actions to reduce threats to sawfishes have been put in place. This is a result of the research-practitioner divide, where the results of research on threatened species do not result in any conservation action on the ground or meaningful improvements to the status of the researched species. For more background on our commitment to bridge the research-practitioner divide and implement activities which will improve the status of sawfishes in the near future, refer to our recent publication and infographic (links available soon), as well as my previous SOSF Keystone project Seeking Madagascar’s sawfishes.
Tanja is learning where the flapper skate moves along the last vestiges of its home range on the Scottish west coast and trying to understand how this affects its genetic diversity. To find out how its declining populations can survive, she is introducing the paternity test to the shark world and exploring whether mating partners, siblings or whole clans are commonly in the same area or if they can be found in different places.
By trawling the fish markets and landing sites of Ghana’s coastline, Issah is surveying the patterns in catch composition over time for sharks and rays in artisanal fisheries. In doing so, he is also raising awareness about the best fishing practices that safeguard sharks and rays and garnering fishers’ support for sharks and the conservation of ocean ecosystems in Ghana.
Juan is collecting environmental DNA (eDNA) samples from the estuaries and mangroves of Colombia’s Chocó region. He is uncovering the presence and distribution of largetooth sawfishes on the Colombian Pacific coast by detecting traces of their DNA left behind as signatures in their environment. The Critically Endangered largetooth sawfish – known locally as ‘El Guacapa’ – is typically found in estuaries and thought to be resident in some of Central and South America’s freshwater systems. Knowing exactly where this sawfish occurs is critical to its conservation.
