Biochemical Changes during the Reproductive Activity in Male Sand Lobster Thenus orientalis (Lund, 1793)

In a situation of increasing anthropogenic activities, assessing their impacts on organisms needs basic information from biological sciences to evaluate the degree of toxicity. Hence, an effort was made to furnish certain vital changes in the biochemical parameters during the reproductive phase in the normal immature and mature male sand lobster Thenus orientalis. The nutrients; protein, carbohydrate and lipid and the enzymes; LDH, NSE, ACP and ALP were estimated and recorded for a deep understanding of the reproductive biology of the taken edible lobster. Highly significant results (p<0.01) were obtained in the testis, vas deferens and hepatopancreas with reference to their nutrient content. Comparatively, elevated LDH was noted in immature forms. Less difference were found in NSE but among the phosphstases, alkaline type exhibited highly significant values (p<0.01) in the reproductive tissue indicating its need. The values registered will aid in the future to estimate the level of impact of any habitat toxicant on the biochemical aspects of maturation of the male sand lobster.
