Turtle excluder devices, commonly called TEDs, promote sea turtle conservation by addressing interactions between sea turtles and trawl fishing gear. These devices are made of metal bars and mesh that fit inside the neck of a trawl net.

A turtle excluder device (TED) is a specialized device that allows a captured sea turtle to escape when caught in a fisherman's net. In particular, sea turtles can be caught when bottom trawling is used by the commercial shrimp fishing industry .

Turtle excluder devices, commonly called TEDs, promote sea turtle conservation by addressing interactions between sea turtles and trawl fishing gear. These devices are made of metal bars and mesh that fit inside the neck of a trawl net.

Turtle excluder devices (TED) have been required in the United States beginning in 1987. The southeastern shrimp fisheries—which once faced severe restrictions and closures to protect endangered sea turtles—have continued to operate while …

2025年1月15日 · The development of Turtle Excluder Devices (TEDs) for trawl nets began in the 1980s in a collaborative effort between NOAA Fisheries, environmental groups, and the U.S. commercial shrimping industry. A TED is a metal oval with parallel bars that is incorporated into the bottom of a trawl net. If a large animal (like a sea turtle) gets caught in ...

2009年1月20日 · Decades of refinement and thousands of sea tests have produced modern-standard TEDs that are 97 percent effective at excluding turtles and, with only very limited exceptions, all shrimp trawls in the United States must carry TEDs.

2023年12月7日 · Known as turtle excluder devices (TEDs), numerous new techniques and additions to existing nets were developed in hopes they would work in the field. This illustration from NOAA shows how a TED works in practice. Multiple versions were tested, with wide variations in success rate.

2023年4月7日 · Turtle Excluder Devices were more thoroughly mandated and enforced in and around US waters in the mid 90s, mandating that all skimmer trawl vessels that are 40+ feet in length utilize TEDs. Some shrimpers in the southeast still do not use them, but the mandation in the US made a dent in bycatch.

Turtle Excluder Devices (TED) in shrimp trawl nets were developed and tested throughout the 1980s and ‘90s in efforts to provide safe methods for turtles to escape almost as soon as they were caught in the net.

A Turtle Excluder Device is a simple metal grid that fits inside the neck of a trawl net. It’s basically a filter: While shrimp pass between its bars to the back of the net, turtles and other larger animals bump against the grid and escape through a flap in the mesh.
