Abstract

The relative yield per recruit isopleths were derived  for Penaeus indicus stocks from Negombo and Chilaw area respectively based on the trawl fishery data collected from July 1984 to June 1986. A maximum relative yield of around 0.041 per recruit can be obtained when the length at first capture is around 11 cm. Although it appears that the fishing intensity can be increased considerably, it should be carried Out concurrently with an increase in minimum mesh size.
