One of the major threats to sea turtles in the marine environment is bycatch, injury, and mortality during fishing operations.
To address interactions between sea turtles and trawl fishing gear, NOAA Fisheries scientists worked with the commercial shrimp trawl industry to develop turtle excluder devices, or TEDs.
What is a TED?
A "Turtle Excluder Device" is a grid of bars with an opening either at the top or the bottom of the trawl net. The grid is fitted into the neck of a shrimp trawl.
Small animals such as shrimp pass through the bars and are caught in the bag end of the trawl. When larger animals, such as sea turtles and sharks, are captured in the trawl, they strike the grid bars and are ejected through the opening.
We considered industry concerns and other public comments in developing and implementing TED regulations. Industry representatives continue to participate in developing and assessing new TED designs and modifications. We gradually phased in TED requirements and have provided numerous workshops and programs to work cooperatively with the industry. We remain committed to working with industry as other geographic areas and fisheries are identified that require the future development and use of TEDs.
TEDs in Other Countries
In foreign shrimp fisheries, NOAA Fisheries and the U.S. Department of State have worked closely with nations that export shrimp to the U.S. to help them develop TED programs comparable to the U.S. program. These programs are now in place in various countries.
The IAC, the first multi-lateral binding treaty devoted solely to sea turtle conservation, is also an important framework to further promote TED programs in other countries.
