Abstract

Additional information regarding the offshore migration of 'karikkadi' (Parapenaeopsis stylifera) during the southwest monsoon period along Kerala coast and its relevance to the management of the local shrimp fishery is reported based on the results of special shrimp surveys conducted during July- August, 1990. In a total of 42 bottom trawling operations conducted between 30 and 90 m depth,'karikkadi' was recorded upto 80 m depth thereby extending the known 'bathymetric' limit of its migration further deep in the study area. The maximum catch was recorded off Cochin at 47 m depth which was far beyond the limit of territorial waters. Biological characteristics such as size frequency distribution, sex ratios, mean size variations and abundance of spawning population are indicated and discussed.
