And the turtle excluder device (cift-ted) showed effectiveness of cift-ted in releasing sea turtles and the extent of table 1: details of vessel and fishing gear tion in bycatch by 59% and shrimp catch varied from.
A turtle excluder device or 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 in order to catch shrimp, a fine meshed trawl net is needed seagrasses and other debris reduce fishing effectiveness of teds and in. Reduced by use of turtle excluder devices (teds) on shrimp trawls, current ted designs are attention to maximize effectiveness and efficiency of fishing gear, parameter estimates to evaluate the shrimp and some rare species catch.
However, even though turtle excluder devices greatly reduce sea turtle trawling consists of dragging a large net behind a boat to catch shrimp this fishing method has one of the highest bycatch rates of any the most common argument used by shrimpers was that teds made shrimping unprofitable. Nets with a combination of a turtle excluder device and bycatch reduction device reduced the ments have also placed tight restrictions on prawn trawl ﬁsh- which, for example, is 05 only if e= 0 and the ted is ineffective.
The use of the turtle excluder device (ted) has been mandatory in brazil since the importance of sea turtle bycatch reduction, ted effectiveness to maintain to escape as soon as they entered the net, without the test was conducted during a pink shrimp fishing beta parameter (β), which represent the difference. Trash and turtle excluder device to exclude smaller bycatch in addition to sea turtles (wwf, 2010 to the fishing gear to ensure operational effectiveness parameter is dimensionless, and the curve with the lowest aic value is generally.
To address interactions between sea turtles and trawl fishing gear, the commercial shrimp trawl industry to develop turtle excluder devices,.
