Abstract

Longtail tuna, Thunnus tonggol, is a neritic species with continuous distribution along the continent of Asia from Iran to mainland China (Yesaki, 1993). The average landings during the 1995-2002 period along the Indian coast was about 5970 t of which 78% was contributed from the North-west region. Although the species has so far been reported to be exploited marginally only, since 1998 there has been a perceptible intensification of fishing activities mainly due to technological advancements all along the Indian coast and especially so along the North-west coast (Anon., 1996). Catches of T. tonggol which has shown an increasing trend along the North-west coast since the early 90s peaked during 2000 and subsequently showed a sudden decline with catches as low as when the fishery was just developing during 1990-92 period.
