Ilse is working with fishers of the largest coastal lagoon in south-east Mexico. Terminos Lagoon is located in the state of Campeche, in the Yucatán Peninsula, and has a fishing history dating back to the Mayans. While Terminos is important to Mexico’s coastal economy and culture, it’s also an important site for sharks and rays. So Ilse will be interviewing coastal fishers to glean insights into the sharks from their fishing tales and lifetime of stories.
Despite living in Mexico City, from the age of seven I have been obsessed with marine life. So I became a hydrobiologist. I was always interested in sharks but had no opportunity to study them in college. So instead I did internships and volunteered in conservation projects that allowed me to get involved in shark and marine conservation. However, I was never the kind of biologist who fits perfectly into a mould. I love being out in the field, but I am also interested in human nature and how people interact. Studying the artisanal shark fisheries in the southern Gulf...
To develop coastal communities’ awareness of the ecological importance of Terminos Lagoon as a habitat for elasmobranchs. We will also recover local ecological knowledge to empower the current generation of fishers to protect local elasmobranch populations.
Terminos Lagoon is an important nursery area for elasmobranchs and a traditional fishing area for local fishers. Nowadays, only old fishers remember that elasmobranchs were once present in the lagoon. It is crucial to recover the local ecological knowledge as every year information that could be used for the conservation of threatened species is lost, and with it the opportunity to empower coastal communities and improve existing management strategies.
There is a great diversity of elasmobranchs in the southern Gulf of Mexico, with about 30 species registered for the elasmobranch fisheries in Campeche. Terminos Lagoon has been recognised as a nursery area for several shark species. Despite the socio-cultural and economic importance of the elasmobranch fisheries in the region, it was only in the 1980s that the fisheries were first categorised by governmental research institutes and only since 1997 that a select few scientific papers have been published. However, these publications do not cover the whole history of the fishery, which could result in a shifted baseline, especially in an area that has experienced intense fishing pressure and has gone through severe environmental changes, including oil spills and coastal development, since the 1940s. Sawfish species have apparently been locally extirpated, which makes it even more urgent to establish a local elasmobranch baseline to identify the most vulnerable species and start planning adequate conservation strategies. Participatory mapping has been proposed as a powerful tool for biocultural conservation, and the use of documentaries in which members of local communities have featured has had the positive effect of increasing local participation, encouraging changes in attitudes towards conservation and empowering communities. This is the first time, to our knowledge, that short videos featuring experienced fishers, participatory mapping to which community members of all ages contribute, and a workshop where this knowledge is transferred, combine to increase local awareness and interest in elasmobranch conservation.
Tom has a once-in-a-lifetime opportunity to tease apart the impacts of human visitation, climate change and fishing on Adélie, Gentoo and Chinstrap penguins. Using drone footage, camera data and faecal samples collected in 2020/21 and into 2022, he’s monitoring Antarctica in years with minimal human footprint due to the Covid-19 pandemic. Tom wants to know whether rising sea temperatures, increasing krill fishing or a growing tourism presence is driving declines of Antarctic Peninsula penguins. By comparing 10 years’ of monitoring data to these data, he hopes to use his findings to inform policy decisions to conserve the Antarctic Peninsula’s penguin colonies.
Demian’s team is developing tools that help border control officers identify illegal shark products. His project is sifting through ‘rhino ray’ DNA sequences looking for differences in code between the guitarfishes, giant guitarfishes and wedgefishes nicknamed for their pointy snouts (and Endangered status). Months of testing will help ensure only rhino ray DNA is targeted before the team flies to Hong Kong to help officials use a portable DNA tester. This project will add to the arsenal currently being used to identify illegal shark fins moving across borders, and help stop the trafficking of ‘rhino ray’ fins.
Aristide created a citizen science platform and mobile app for fishers across Cameroon’s 400 km coastline to record sightings of sharks, rays and marine life. These photos are uploaded to iNaturalist where they are identified and will serve to create Cameroon’s first elasmobranch atlas. Together with his team, Aristide ensures data are being uploaded, visits fish landing sites to assess bycatch and measure sharks, and scours the beaches to check for strandings and sea turtle nests. He collects tissue samples of threatened species in these visits that can give more insights into the diversity, population size and structure of vulnerable sharks.
