In the U.S., turtle excluder devices (TEDs) were designed to protect sea turtles and are required in shrimp trawls.Ī TED is a grid of bars in the neck of the net with an opening, reminiscent of an escape hatch. Sea turtles are prone to drowning when they are caught in trawl nets and are crushed or are unable to escape to the surface to breathe. Trawling can occur with one boat pulling a net or by two boats, each pulling an end of a much larger trawl net. Catching unwanted species is a problem for trawlers because it is a very indiscriminant form of fishing. This fishing gear is typically used to catch fish or shrimp. ![]() 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 TrawlsĪ trawl is a large net that is pulled through the water column or along the seabed, catching anything that is not small enough to pass through the net’s mesh openings. ![]()
