anaging by-catches in longlining is crucial for the sustainability of marine ecosystems. Here are the primary methods employed: Circle Hooks: These reduce by-catch mortality, especially in sea turtles, compared to traditional J-hooks. Bait Selection: Specific baits can deter unwanted species, minimizing by-catch. Bird Scaring Lines: Streamers deter seabirds during longline setting, preventing them from taking bait. Depth Adjustments: Setting hooks at strategic depths targets specific species, reducing incidental catches. Training and Education: Crews trained in best practices can effectively release non-target species, enhancing their survival. Area Closures: Closing high by-catch or ecologically sensitive regions helps protect vulnerable marine life.
