Proximate chemical composition and occurence of some pathogenic bacteria in frozen from upper east coast of India

Abstract

Some studies on bacteriology and proximate chemical composition were carried out the frozen fsh and shell fish samples brought from 27 th cruise of FORV Sagar Sampada. Out of 21 samples screened for bacteriological studies, 17 samples have shown the presence of enterobacters , 12 samples contained Pseudomonas and proleus was found in two samples. Salmonella and shigella were absent in these Samples. The edible muscle of frozen and thawed samples was analysed for moisture, protein, fat, ash and nutritive minerals like calcium, phosphorous and iron. The total protein content of the muscle of different fishes studied varied from 1625 to 20.88 per cent on wet weight basis. The fat content is found to be more in deep sea fishes namely black ruff (6.074 per cent ) and psenes (3.796 per cent ) than in other common varieties of inshore fishes analysed.
