November 22, 2022 — Millions of sharks, rays, and skates are accidentally killed every year as bycatch within the global fishing industry—an especially staggering number when considering that a quarter of all those species are currently considered endangered. Previously, fishers could do very little to discourage the predators from going after the longline bait meant for intended targets like tuna, but a simple and ingenious new technology is showing huge promise in finally changing course. Highlighted via a study published earlier today in Current Biology, a small device dubbed SharkGuard recently decreased the number of unintended shark catches by as much as 90 percent through exploiting one of the animals’ most impressive senses.
