Description The prawns which are useful for cultural purposes belong mostly to the decapod families Penaeidae and Palaemonidae. Most penaeids are marine prawns which migrate to estuaries and brackish water in their young stages but go back to the sea to breed. A small number of them breed in coastal inlets and others are exclusively marine. Species of marine Palaemon are highly adaptable to lower salinities. The habitat of Palaemonetes ranges from sea water to fresh water while Macrobrachium is largely a fresh water genus. Species of Macrobrachium include those which migrate from fresh water to brackish water during the breeding season. The marine penaeids and palaemonids show capacities for hypo-osmotic regulation when in sea water and high powers of hyper-osmotic regulation in brackish and fresh water. They have not developed extreme specialization as fresh-water inhabitants in that their normal blood osmotic values are high as compared with old established fresh-water crustacea and they do not produce hypotonic urine for conserving salts. These features have endowed these prawns with unusual adaptational abilities to live in variable surroundings, although each species has its own optimal range
