Quantification of Nutritional Components on Some Selected Species Collected from Ennore Estuary, Tamil Nadu, India

Throughout many parts of the world, marine and aquatic organisms have long held a crucial place in human diets, often serving as the primary source of animal-derived protein for certain communities. This diverse food category, which includes fish, various crustaceans (such as crabs), and molluscs, is broadly acknowledged for its substantial nutritional value. The Ennore estuary is a remarkably vibrant and biodiverse ecosystem, supporting a multitude of different species. This current research endeavours to analyze the nutritional profiles of several pivotal organisms harvested from this unique environment. Specifically, the study quantifies key nutritional parameters, moisture content, crude protein, total fat, total carbohydrates, and dietary fibre in a selection of eight important aquatic species: Nile Tilapia, Bengal tongue sole, Asiatic hard clam, Common oriental clam, Giant Tiger prawn, Indian white prawn, Blue crab, and Mud crab. The results shows that the Penaeus indicus has more protein 22.50%, carbohydrate and lipid content was more in Portunus pelagicus 9.21% and 7.88% respectively.
