SummaryThe stocks of shrimpsParapenaeopsis styliferaandMetapenaeus dobsoniin the fishery of two areas of Kerala coast in India have been studied using length frequency data. The average annual stocks of the two species have been indicated. The present status of fishery shows a differential fishing pressure for males and females ofP. stylifera, resulting in favourable recruitment of the species in the fishery, while this is not so in the case ofM. dobsoni.The study suggests the necessity for reduction in the fishing pressure in order to maintain MSY levels.
