Abstract
Variations in the composition of fish landed by demersal trawls of five different
designs during the period of 1988-1993 off Veraval coast are reported in this paper.
The average catch/h was 48.53 kg for the entire period. The catch rate was maximum
(58.46 kg/h) during 1988-89 and it declined to 28.73 kg/h in the year 1992-93. The
catch was dominated by ribbon fish (17%), cephalopods (8.7%) and sciaenids (12.9%)
during the period. There was no significant difference in the catch rate of individual
species in depth ranges of 20-30 and 31-40 m.
