Abstract

Ribbonfish, Trichiurus lepturus (Linnaeus) has become one of the most important exploited resources in the northwest coast of India. It was landed as bycatch of shrimp trawler earlier but on account of emerging export demand it is now increasingly targeted. The resource has been monitored for more than ten years. The landings of ribbonfishes varied between 16,000 t (1995) and 63,000 t (2000) with an average catch of 33,000 t. The trawl contributed about 93 % of the total landing. Peak catch rates were observed in September and November-December. T. lepturus is a carnivorous predator feeding on crustaceans, fishes and cephalopods. Spawning season is prolonged from October-May. Individual fish spawns once in a year and the minimum size at maturity is 75 cm. The fecundity varied between 4,900 and 81,000 with a relative fecundity of 65 ova/gm of body weight.
