Abstract

Deep-sea prawn landings from 10 fisheries harbours of Kerala during September 2000 to April 2001 have been quantified as 48675 t. The deep sea trawl units showed almost a double fold increase during 2001-02. Aristeus alcocki, Heteracarpus gibbosus, Heterocarpus woodmasoni, Parapandalus spinipes and Metapenaeopsis andamanensis, were the major species of commercial importance which accounted for major portion of the landings. Species wise catch and catch per effort from various fisheries harbours of Kerala are furnished. Life history traits such as size range and modal size constituting fishery, sex ratio and percentage of berried females in the exploited stock deep-sea prawns are also given.
