July 2, 2018 — Tens of thousands of people die every year trying to catch fish to eat or sell, and weather is one of the biggest hazards to lives and equipment. The International Red Cross estimates that 3,000–5,000 people, mainly fishers, are killed by intense thunderstorms on Africa’s Lake Victoria each year. In 2013, Typhoon Haiyan destroyed some 30,000 fishing boats in the Philippines.
The dangers of fishing are no secret, but a warming planet could make the job even more risky. A team of researchers in England is calling for a closer look at how increasingly stormy weather will affect global fisheries.
In a study published in the journal Nature Climate Change, they warn that nastier weather in the future will make fishing more dangerous for millions of fishers and, by reducing catches, could threaten the health and well-being of billions of people who eat seafood. The biggest challenge is that few have studied this question. Although there’s been plenty of research on how ocean warming could reduce fish catch in the next 50–100 years, they said, changing “storminess” could actually be a more immediate, catastrophic issue.
“We really want to encourage more research in this area, because we think it’s really critical for the future,” said lead author Nigel Sainsbury, a scientist at the University of Exeter’s Environment and Sustainability Institute.
Already, scientists have looked at how large storms can damage coral reefs, cause fish to evacuate large areas and flood estuaries with salty ocean water. Some storm systems may also benefit fish by strengthening ocean upwelling that allows phytoplankton and zooplankton – food at the base of the marine food chain – to thrive, according to research led by United States National Marine Fisheries Service scientists.
