For sharks, the Mesoamerican Reef, which stretches over 600 miles, is a busy highway. Sharks use it to find their way and it provides them with food and habitat.
But as with on-land highways, this superhighway can be dangerous. Overfishing, commercial development and illegal practices are endangering the species. "We're seeing a continued decline in shark populations. Our goal is to turn that round." says Rachel Graham, founder of Mar Alliance, a non-profit organization focused on conserving sharks.
By monitoring sharks, Mar Alliance can collect important knowledge on the species to help inform conservation and push for political action. But rather than acting in opposition to the local fishing community, MarAlliance enlists their help.
"They are the ones who are on the sea every single day," says Graham, "and they're the ones who decide the species' future."
MarAlliance employs up to 60 fishermen across its range, mostly on a project basis, training them to collect data, record and release fish. Not only does this provide an alternative income to fishing communities, making them less dependent on natural resources, but it also teaches them about the benefits of a healthy ocean ecosystem and how to fish sustainably.
Among them, Ivan Torres, who used to catch sharks to sell locally as food, has learned how critical they're to the whole ecosystem, saying he'd never fish sharks any more.
If this attitude change continues to spread throughout fishing communities, Graham has hope for the shark populations. "The primary threat to sharks is unquestionably overfishing," she says, "By reforming the industry, populations can bounce back."
In 2020, Belize outlawed the use of gillnets, large panels of netting of trapping large sealife. The ban's impact is already noticeable with a recorded 10-fold increase in shark populations.
But such regulations need to be copied along the whole superhighway for long-lasting impact, and countries need to find a sustainable balance between fishers and the fished. "We need to find a win-win strategy between fisher livelihoods and shark survival," Graham emphasizes. "I hope that through education and providing an economic alternative for fishing communities, MarAlliance will help ensure safe passage for sharks along the reef".
