Penaeid prawn population and fry resource in a mangrove swamp of Goa, India
Abstract
Penaeid prawns abundantly occur in the mangrove swamp during the premonsoon season. They are constituted by the commercial species, Penaeus merguiensis, Metapenaeus dobsoni and M. monoceros. Recruitment of the swamp takes place when the individuals are between 10 and 20 mm in size. Growth rate and period of stay in this environment vary with species. About 46.5% of the population is comprised of juveniles ranging in size from 10 to 30 mm. These could be collected in large numbers between December and June for aquaculture purposes
