Incidental catch of Spinner dolphin Stenella longirostris

Spinner dolphin Stenella longirostris (Gray,1828) was incidentally entangled in an encircling gill net (55 mm mesh size) off Mangaluru on 18th September, 2013 and landed at the Mangalore Fisheries Harbour (Fig. 1). The mammal was found entangled in the net deployed at about 60 m depth around 04 00 am in the morning. Fishermen were of the opinion that Spinner dolphins mostly get caught in the net when the water is turbid and visibility is low
