The sea food is considered highly nutritious and less harmful when compared to other red meats. In the present study, the total heterotrophic bacterial population density was recorded in four different site fish samples. The microbial load of freshly caught fish was low, ranged from 1.21×103 to 1.42×103, followed by fish after two hours 7.62×103 to 8.83×103, fish at landing center were 2.0×104 to 3.22×104 and fish at market ranged from 4.91×104 to 6.07×104. The total microbial load was increased along with pathogenic microbes. In this study totally 25 strains were isolated from fish samples, of these isolates 9 genera were identified based on the biochemical characters. The names of the bacterial genera were Vibrio (17.5%), Pseudomonas (22.5%), Shigella (5.75%), Bacillus (15.25%), and Escherichia coli (15.5%), Klebsiella (8.5%), Staphylococcus (7%), Corynebacterium (5%) and Salmonella (3%).
