Before turtle excluder devices (TED) loggerhead turtles were casualties of shrimping operations

A turtle excluder device

A combination turtle excluder device/bycatch reduction device manufactured by Saunders Marine Machine Shop. Fish escape by swimming forward and out of the large holes in the net. Shrimp are swept into the bag at the end of the net and cannot swim out.

Turtle excluder device (TED) manufactured by Saunders Marine Machine Shop. The oval metal ring and bars deflect the turtles. The cut in the netting is where the trap door will be placed. The bars force a turtle to the trap door which will open allowing the turtle to go free.

TED's for sale. Although early in their development use of TED's were resisted, they are now a routine part of any shrimp trawl vessel. TEDS are shown for sale in the window of this Biloxi marine outfitter.

Closing the purse seine. This picture of early tuna purse seining operations illustrates that often dolphins and other marine mammals were caught as a byproduct of tuna fishing. Today, efforts are made to minimize the harm to marine mammal species during tuna purse seining operations.
