Crabs are not a targeted resource in India, although they are available in the local and international markets. The crab fishery in India is fast developing and there is a vast scope for the crab meat, both national and international markets. Crabs are an incidental catch in trawl and they are also caught in meager quantities by specialized gill nets, locally known as ‘Nandu valai’ in Tamil Nadu. The commercially important portunid crabs found along Nagappattinam coast is Portunus sanguinolentus. The fishery and stock characteristics of the dominant species of crab, Portunus sanguinolentus was studied along the Nagappattinam coast. Hence it will be pertinent to describe the fishery of this important resource and also to study the biochemical characters of the dominant species, P. sanguinolentus off Nagappattinum. The results of the present study concluded that the protein and carbohydrate content were higher in ovary followed by hemolymph, muscle and hepatopancrease while amino acid and lipids were higher in ovary followed by hemolymph, hepatopancrease and muscle. The rich source of biochemical (Protein, amino acid, carbohydrate and lipid) content was found in P. sanguinolentus.
