    Abstract

    Three different set of experiments were conducted using normal seawater, filtered seawater and re-circulatory system for the improvement of meat quality of the green mussel {Perna viridis) in terms of bacterial quality and biochemical composition. Total plate count, faecal streptococci count, and conforms were examined to analyse the bacterial load of mussel and the surrounding water. The most significant bacterial reduction was obtained in the re-circulatory system followed by filtered seawater. Coliforms and faecal streptococci were able to completely eliminated from the mussels through these treatments. The experimental mussels were fed ad libitum with cultured micro algae during the experimental period. The nutritional quality of mussel meat studied in terms of biochemical components showed clear significant difference between control and experiment. The condition index, dry meat weight, protein and carbohydrate percentage of the mussel meat was found to increase significantly at the end of all the experiments. The studies showed that the meat quality of the mussels harvested from nature could be improved in terms of bacterial reduction and at the same time increasing the nutritional quality through these types of short-term treatment in captivity by providing feed and quality seawater.
