The accidental\ncatch (by catch) of sea turtle in marine environments is a major threat to sea\nturtle populations worldwide. Often, turtles caught in fishing gear are injured\nand\/or drowned.<\/p>\n\n\n\n

According to published\nestimates by Oceana, about 50,000 endangered and threatened sea turtles are\nannually killed by Southeast shrimp trawls (USA). (South Atlantic and Gulf of Mexico waters). <\/p>\n\n\n\n

In the 1980s, the\ncontribution of shrimp trawlers to sea turtle mortality was determined. Consequently,\nthe Turtle Excluder Devices (TED) were developed throughout the 1980s and \u201890s for\nconserving sea turtles caught in the shrimp\ntrawlers.  <\/p>\n\n\n\n

A TED is a\ngrid of metal bars which is fitted into the neck of a shrimp trawl net with an\nopening either at the top or the bottom mesh to enable a turtle caught in the\nnet to escape. The small animals such as shrimp pass through the bars into the\ntail bag of the trawl net and are caught. When turtles and other large animals,\nsuch as sharks, and stingrays are captured in the trawl, they are stopped by\nthe TED, strike the grid bars and are ejected through the opening.<\/p>\n\n\n\n

The use of TED has been enforced in\ncountries where shrimp trawling is commonly practiced. For example, a Public Law\n101-162 in the USA requires the banning\nof the importation of commercially harvested shrimp unless the exporting\ncountry has been certified by the State Department as having a regulatory\nprogram comparable to that of the United States for reducing the incidental\ncapture of sea turtles in shrimp trawls. TEDs have been required in the United\nStates beginning in 1987. At present, around 40 countries are certified that\nthey have comparable sea turtle bycatch rates to the United States.<\/p>\n\n\n\n

The focus of TED\ndevelopment has been always to provide safe methods for turtles to escape\nalmost as soon as they were caught in the net. Equally important was to preserve\nthe shrimp catch; the target crop. The periodic development of TEDs has been\nbased of the practice findings and emerging issues. For example, modified\ndesigns of TEDs targeted to accommodate small-sized sea turtles such as the\nKemp\u2019s ridley. Equally important, the reduction of the unwanted fish bycatch has been considered in the TED development.<\/p>\n\n\n\n

The\nNational Oceanic and Atmospheric Administration – Fisheries (NOAA) reported that TEDs were able to save up to 97% of sea turtles\nwith minimal loss of shrimp. \n\nAccording\nto some official reports, the use of newly developed TED would lead remove\nshrimp trawlers from \u201cred-lists\u201d on seafood buying guides, and hence help the opening\nof new retail markets to their catch as well as help ensure healthy sea turtle\npopulations, improving the value of nature-based tourism.\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
