NOAA Fisheries is currently working on a strategy to implement the survey in locations along the Atlantic and Gulf of Mexico coastline, with potential expansion to the West Coast and Pacific Islands at a later time. The form contains questions similar to the fishing survey so we can compare the results on angler fishing practices and sea turtle interactions. NOAA Fisheries has also developed an additional form for Sea Turtle Stranding and Salvage Network participants to use when responding to a sea turtle that has been caught on recreational fishing gear. With this information, we hope to identify new best practices for fishing around sea turtles. To help gather this information, NOAA Fisheries has created a survey to learn more about the interactions between recreational anglers and sea turtles and other protected species. NOAA scientists are looking for ways to better understand how frequently these interactions occur, what factors might increase the likelihood of interactions, and how to prevent interactions from occurring. Along the Pacific coast, anglers in Hawaii and California are also known to unintentionally catch sea turtles. These interactions can occur anywhere sea turtles are found and have been documented on the eastern coast of the United States from Massachusetts through the Gulf of Mexico to Texas. Sea turtles may also be attracted to fishing bait and become hooked in the mouth or swallow the hook. When swimming near rod and reel fishing gear, sea turtles can become hooked on the body or entangled in the fishing line. ![]() Sea turtles and other protected species are accidentally caught in many types of fishing gear, including commercial and recreational gear. federal court effectively shut down the swordfish fishery in the central Pacific.NOAA Fisheries is interested in learning more about how sea turtles interact with gear fished by recreational anglers. Recent court action has raised awareness about the dangers of longlines. Loggerheads and leatherbacks have the greatest risk because of their feeding habitats.ġ) Green turtles, loggerheads, olive ridleys, and leatherbacks occasionally eat the bait and become hooked on longlines.Ģ) Leatherbacks can also be attracted to chemical light sticks (used to attract fish) on the longlines, perhaps confusing them for jellyfish luminescence, and causing entanglement. Subsequent mortality tends to be higher for hooked turtles than for entangled ones.Īll sea turtles are affected by commercial fisheries. Sea turtles that are hooked and released alive often retain hooks in their flippers or digestive systems and this invariably causes severe injury and usually a slow, painful death. A recent study by Duke University found that 250,000 loggerhead and 60,000 leatherback turtles are estimated to be inadvertently snared each year by commercial longline fishing. It is estimated that 300,000 seabirds die on longlines each year. Hundreds of thousands of non-target species are hooked and killed every year. Without careful management, longline fisheries can have unintended interactions with non-target fish, seabirds, and other marine life, as known as by-catch. ![]() Every 12-24 hours, the line is hauled in, mechanically re-baited, and set back into the water behind the vessel. The lines are baited with mackerel, squid, or shark meat and have as many as 10,000 hooks. Usually, at about every 100 ft, a secondary line is attached and hangs down from the mainline. ![]() The line itself is buoyed by Styrofoam or plastic floats. Longline fishing utilizes fishing lines that can be as much as 62 miles long. Longlines are used for the capture of pelagic (open ocean) species of fish such as tuna and swordfish.
