Abstract
A traditional method in which rice-prawn rotation culture is practised in low lying paddy fields surrounding the Vembanad estuary in the south-western coast of India is described. A long stemmed salinity tolerant variety of rice is cultivated from June to September. During harvest most of the straw is left in the field. The fields are then leased out to prawn farmers for a period of 5 months from mid-November to mid-April next year. Prawn larvae coming in from the sea, probably attracted by the comparatively lower salinity and the plentiful availability of food in the fields, are trapped. Harvesting starts from about mid December and continues till the middle of April. Prawns form about 80% of the catch. This system continues to survive and be profitable even with the generally declining trend in rice cultivation in Kerala state. A thorough study into the various aspects of the production dynamics of this unique and highly efficient culture system could provide valuable information; particularly for other regions with similar conditions.
