Management
Catch of several commercial species like P. indicus, P. semisulcatus, M dobsoni, M. monoceros and P. stylilera had crossed the MSY. Estuaries and backwaters are nursery grounds for many commercially important penaeid species (M dobsoni, M. monoceros and P. indicus). Use of stake nets in these areas need to be restricted as it results in juvenile overfishing. Minimum size of cod end of the trawl net needs to be 25 mm. Extension of fishing to areas beyond conventional fishing grounds has to be encouraged by offering suitable subsidy. Large-scale sea ranching of the post-larvae needs to be done. Trawling within 10 m depth by commercial trawlers as well as mini trawlers should be completely stopped in order to avoid exploitation of the juvenile prawns/ shrimps.
