Abstract
It is an established fact that the world population swells at an alarming rate year after year, and over half of the same is believed to suffer from malnutrition. At the present rate of population explosion it is likely that the global population may up from the present level of 5 billion to about 8 billion by the close of the present centuary (Becker, 1992). The food from land is so limited that it may not be able to satisfy even the basic requirement of the ever increasing population. One of the alternative to overcome this problem of food shortage is to tap the vast resources of the ocean which could nourish the human population many times more than its present level. According to FAO fishery Statistics the world fish production in 1990 amounted to about 97 million tonnes of which 95.8 million tonnes have come from the sea. Crustaceans comprising of prawns lobsters and crabs accounted for about 4.4% of this, which are the most highly valiJable commodities t:!{ virtue of their pivotal role in the seafood industry of the world. In India, the marine fiShery is mostly export oriented and among the seafood items exported from the country, the crustaceans account for 80ut 45 % in terms of volume and 75% in terms of value. According to the latest export figure, this amounts to about 14,000 million rupees annually (Sukumaran, 1992). Among edible crustaceans crats occupy the third rank, the first and second positions being given to prawns and lobsters on account of their demand in the overseas markets. Crab meat is considered as a delicacy in many parts of the world and within the country it is an important source of protein rich food for the less affluent society of coastal areas. .Besides its immense nutritive value, the crab meat also carries many therapeutic properties. Crab shells are rich source of chitin and its chitosan content which have numerous industrial and medicinal applications, particularly in the manufacture of artificial fabrics, printing inks, photographic emulsions adhesive cosmetics, dialysers and anticoagulants (Mendenhall, 1971, Muzzarelli and Pariser, 1978, Sambasivan, 1992). It is estimated that the world export earnings from chitin would be about 200 crores dollars by the end of 2000 AD (Girish Babu, 1990).
