Assessment of the Bacteriological Profile of Water and Fish Samples from Hadejia Reservoir in Jigawa State

Hadejia reservoir is a floodplain complex in northeastern Nigeria. This area has long been noted for its importance in fish production. It is also important to both year round native birds and European water birds that travel over the Sahara desert to this wetland to spend their winters. Quantitative and qualitative profile of bacteria in the reservoir was carried out. Quantitative analysis of bacteria in the water revealed that the water Contained Total Heterotrophic Count (THC) of 3.110 super( 3) to 3.5l0 super( 6) CFU mL super( -1) and Total Coliform Count (TCC) ranging from 1.410 super( 2) to 1.410 super( 5) CFU mL super( -1). Bacteria load in the fish intestines are 3.510 super( 3) and 3.1l0 super( 4) CFU g super( -1) for total coliform and total heterotrophic count, respectively. Fish gills has less count (2.110 super( 2) and 3.410 super( 3) CFU g super( -1) for TCC and THC, respectively) than the fish intestines. Bacteria species such as Aeromonas hydrophila, Vibrio cholera, Shigella species were isolated from the water samples. Escherichia coli, Salmonella sp. and Shigella sp. were isolated from the fish samples. So, the present study aims to assess the bacteriological profile of water and fish samples from Hadejia reservoir.
