The total fish catch was 9,767 kg. Catch per unit effort was 194.7 kg/ h for HSDT, 1,085.3 for HOT and 83.4 for HT. Average vertical height obtained with Integrated Trawl Instrumentation (ITI). 48% of the catch was Rastrelliger kanagurta, 11% Ariomma indica, 8% Secutor sp., 6% Arius sp. and the rest miscellaneous demersal species.
