    Penaeid shrimps are, perhaps, the most important fishery resource of the coastal waters of our country. Their exceptionally tasty, protein-rich flesh tops any seafood in for eign exchange earnings. No wonder, the demand oC shrimp, the "Pinkish Gold of the Sea" OIPEDA, 1992), is increasing in the world market. The high demand of shrimp in the developed countries, espec ially USA and Japan, since the beginning of the sixties, has been a strong incentive Cor de veloping countries with good shrimp fishery grounds, to concentrate on this Cisher y . Although penaeid species are Cound in all the seas of the world upto subpolar latitudes, their . distribution is mainly tropical and subtropical (Wickins, 1976a). Most oC the species of high commercial value, and their most productive fishing grounds, are d istributed between the tropics (Pedinl, 1981). The high demand and the high price ot shrimp in the International market have led to a rapid increase in the number of shrimp trawlers in the fishing fleets oC the developing countries, r esulting in inte nsive exploitation, rather overexploitation, of this resource; shrimp fishery of many of the countries, t hus, has been de ple ted , is fast dwindllng, or has reached the maximum s ustainable yield . The global production of shrimp by capture had already levelled oft in 1985 at 1.9-2.0 million mt. The a verage annual growth from 1985 to 1990 was only 0.02% ; indeed negligible by all standards (Csavas, 1993). Since the capture shrimp fishery in terms of CPUE has been stagnating for the last several years, any further increase to close the supply-demand gap can be achieved only through aquaculture; shrimp c ulture has already gained considerable momentum in many parts of the world.
