Estuaries are highly productive, dynamic and unique ecosystems providing food, transport, recreation, etc. Mangrove vegetation, ranking high in productivity, is often associated with tropical and subtropical estuaries. Quality aspects of bivalves (Meretrix casta and Anadara granosa) in the Muthupet estuary were examined in different season over a 12 month period and also different body parts. Nutritional quality parameters of bivalves were determined at different seasons of the year. Seasonal variations were observed in the nutrient content, with particular observed in the nutrient content, with particular regard to average value of protein was 56.10%, carbohydrate 4.1%, lipid (3.30%) lipase 0.4% and protease 0.12% in Meretrix casta whereas in Anadara granosa protein average value of protein was 55.68% and lipid 4.71%, lipase 0.13% and protease 0.14%. Inspite of this variability, the nutritional quality of the bivalves was generally good. It could also be added that the composition of marine bivalves is a nutritional assurance to millions of malnourished people. |
