Abstract

The growth and development of scientific aquaculture in the country is of recent origin although it is highly skewed towards shrimp culture. The diversified coastal aquaculture practices adopted in the country are different culture systems for shrimps, mud crab, various species of finfishes etc. Economics of both improved traditional and extensive systems of shrimp culture practices were discussed. All the farmers practicing traditional prawn filtration selectively stocked their farms with either Penaeus monodon or Penaeus indicus or both. The costs and returns of crab fattening, milk fish culture and polyculture system with fishes were assessed. The cost structure of different culture practices were analysed and determined. Aquaculture is the most ideal and viable alternative available for productive employment without any displacement for the fishers in our coastal zone. In Kerala, hardly one third of the potential brackish water area is currently utilised for one or other aquaculture practices. The fresh water aquaculture sector in India surpassed the production from brackish water and marine regions due to the spectacular technological developments in culture, hatchery operations and feed manufacture with their high adaptability. It is high time to bring at least half of our potential brackish water area under culture with the diversified species. The various shortcomings in popularizing these culture practices are discussed and the possible solutions suggested
