CIFT Turtle excluder device (TED) installation in shrimp trawl nets intent to reduce the incidental catches and mortality of sea turtles of India. Sea turtles play a significant role in maintaining the balance of the food web in marine ecosystem. Among the five species of marine turtles, Olive ridley is the widespread species in Gahirmatha, Orissa, along north-east coast of India. Incidental mortality of sea turtles is due to the fishing practices such as trawling and gill netting operated in India. CIFT-TED, a single-grid with a top opening consists of a 1000×800 mm stainless steel oval frame with inside five 8 mm vertical grid bars is welded and fixed at a 45°angle. CIFT- TED experiments were successfully conducted in Cochin, Gahirmatha, Paradip, Debi and Visakhapatnam coast of India. CIFT-TED saves sea turtles with minimal catch loss as per the experiments conducted in west and east coast of India.
