Abstract

The annual trawl landings at Chennai increased from 29,130 tonnes in 1991 to 42,649 tonnes in 1994 and subsequently decreased to 34,069 tonnes in 1995. Consequent upon extension of operation upto Nizampatnam. the contribution by the multi-day trawlers increased from 35.4% of the total landings in 1991 to 52.5% in 1995. However, the catch rate of the trawlers decreaced from 110.8 kg.h-' (1991) to 48.3 kg.h-' (1995). The trawling effort of daily and multi-day trawlers has to be reduced to obtain Maximum Sustainable Yield. The extended trawling activity of Chennai based trawlers has influenced the operational pattern of trawlers of south Andhn Pradesh coast. The catch, effort and catch composition of trawlers based at Krishnapatnam and Nizampatnam have also been analysed.
