Economics of diversified coastal aquaculture production systems in Kerala

Sathiadhas, R and Joseph, Juliet (2001) Economics of diversified coastal aquaculture production systems in Kerala. In: Proceedings of the International Workshop on Aquaculture and Environment , 13-14 July 2001, Kochi.



The farming of shrimp, crabs, edible oysters, mussels, pearl oysters and lobsters offer immense scope not only for augmenting the aquatic production but also to increase our export earnings. Kerala is bestowed with 65,000 ha of brackish water area suitable for aquaculture activities. Shrimp farming has been the thrust area all these years and it is currently confined to less than 15,000 ha. There is enough scope to develop diversified culture practices in the unutilised potential areas. Different production systems like semi- intensive and more intensive prawn culture, crab farming and crab fattening with composite fish-prawn farming are analysed to assess their cost and earnings and their comparative economics. Semi-intensive shrimp farming and crab fattening are found to be the highly profitable ventures. Indicative economics of open sea mussel farming and edible oyster culture are also given. The problems in adopting these production systems are discussed and some suggestions have been put forth for their further expansion and improvement.
