ABSTRACT: Biochemical analysis was carried out in tissues of the male crabs belonging to different maturity stages were collected from pulicat lake and the biochemical changes studied correlated with the nutritional aspects during the reproductive activity and developmemtal changes correlated with nutritional aspects occurring in the gonads and other organs like hepatopancreas and muscles have monitored with regard to different types of isoenzymes such as LDH , and esterase activity taking place in the different tissues during maturation have been studied and quantified.The trends in the fluctuation of metabolites indicates that the transactions takes place from the chief synthetic and storage organ. During the reproductive activity, the levels began to increase at certain stage and high levels were maintained during higher developing stages with growth and these levels decreased during prespawning , ecdysis and molt cycles and correspondingly maturation stages.It showed high levels of changes which were not in advance in the immature and developing stages . A considerable importance on the changes in different tissues in the aquatic animals in accordance with the reproductive activities has been noted in the present study of the crabs of Uca triangularis Bengali.of pulicatlake.
