ndia ranks second ,only to United states in prawn production (Mohamed. 1973) and earns valuable foreign exchange from export of this crustacean to the tune of Rs.329.70 crores. which formed 85% of the total shipment. of marine products in the year 1984-85 (Anon., 1985). Increasingly expanding demands for prawns at enviable profits in overseas markets, coupled with concurrent technological advances, have enormously increased the exploitation of natural stocks in recent years and raised the possibility or even probability of over-fishing which may eventually leads to the total disaster of the fishery itselt. It emphasises enforce- ment of rational fishing to ensure a long-term sustainable yield. In order to monitor the impact of increasingly intensified commercial fishing, the stock positions of prawns have, therefore, been periodically reviewed (Chopra. 1943; Panikkar and Menon, 1956; Bh1machar. 1963; Banerjl, 1969; Jones. 1969; Mohamed, 1973; Silas etal.,1981). Since each species, that constitutes the fishery has its characteristic beha- viour. movements and habitat a long-tem fishing may have varying degree of impact on each one of them. This necessitates in-depth studies on individual species with regards to the resources available and exploited.
