Abstract

Silky sharks Carcharhinus falciformis (Müller & Henle, 1839) are large oceanic sharks, known to be circumtropical in distribution, occurring mostly in the subtropics between 40æ%N and 40æ%S. They are highly migratory, known to inhabit continental and insular shelves and slopes, deep water reefs, and the open sea. They are also occasionally sighted in inshore waters. They are solitary in nature and are often found near schools of tuna, increasing the chances of forming a bycatch of tuna fisheries. These sharks have been reported in the fishery only along the southwest coast of India, and were recorded in small numbers at Cochin during 2000-2002. In 2010 however, this species formed about 16.3% of the shark landings at Cochin. In spite of this, these sharks have not formed a fishery along the east coast.
