Abstract

Surge in fishing effort and penaeid prawn catch was recorded during the study period with that of 2006-10. Decline in Catch per Hour (CPH) and penaeid prawn ratio (%) to total fish catch was observed. Penaeid prawns accounted for 15.5% of the sona boat landings. Annually, mean penaeid prawn landings were estimated at 6,184 t. Prawn catch excelled by M. monoceros (20.5%), S. crassicornis (13.7%) and M. barbata (7.8%).
