Abstract:
The present study was conducted for microbiological assessment of ten available marine fish species of three different feeding habits collected from three different markets of Noakhali district from July, 2012 to April, 2013. For this, Total Bacterial Counts (TBC), Total Coliform (TC), Fecal Coliform (FC) and the occurrence of Salmonella and Vibrio spp., were determined by using serial dilution and spread plate technique. Among three feeding habits, the highest TBC (2.67±1.69x108 CFU g-1), Vibrio (2.37±1.83x103 CFU g-1) and Salmonella spp., (2.19±1.26x103 CFU g-1) were found in carnivorous and the highest TC (4.74±0.16x106 CFU g-1) and FC (2.03±0.72x105 CFU g-1) in omnivorous fishes. Among 10 marine species, Spotted Croacker, Greenback mullet, Asian Seabass contain the highest TBC (5.09±3.73x108 CFU g-1) and TC (4.18±4.01x106 CFU g-1); FC (2.54±1.95x105 CFU g-1) and Vibrio spp., (1.39±2.09x104 CFU g-1); Salmonella spp., (3.5±2.36x103 CFU g-1), respectively. TBC (2.99±2.76x108 CFU g-1), TC (1.79±0.25x106 CFU g-1), FC (2.23±1.45x105 CFU g-1), Vibrio (9.16±1.36x103 CFU g-1) and Salmonella spp., (2.55±2.01x103 CFU g-1) were the highest in gill and the lowest in skin. Among fishes of three different markets, the highest TBC (2.16±0.96x108 CFU g-1), FC (1.73±1.08x105 CFU g-1) and Salmonella spp., (2.72±0.86x103 CFU g-1) were found in the fishes of Dutter hat and the highest TC (1.13±0.45x106 CFU g-1) and Vibrio spp., (4.38±1.02x103 CFU g-1) in the fishes of Sonapur market. Bacterial densities of these fishes were higher than the acceptable limits. Findings of the present study suggest that marine fishes may act as reservoirs of harmful pathogenic species which creates many dangerous diseases such as cholera, typhoid etc. and the consumers should be careful about the qualities of fishes.
