Seasonal variations in the intestinal bacterial flora of Oreochromis niloticus cultured in farms
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 3
Abstract
Microbial contamination in different food items is becoming a hazardous problem now a day. The present study was conducted to examine intestinal bacterial flora of tilapia (Oreochromis niloticus) in different seasons of the year. Fish and water samples collected from fresh water fish farms were tested for the determination of microbial load by culturing on different bacterial growth media. The water samples were analyzed for physicochemical properties. The results obtained were compared for microbial population in the intestine of fish samples collected in winter, spring and summer seasons from the same locality. Data was tested to appropriate statistical model to determine significance and non-significance among various parameters. The result showed that bacterial flora was more in autumn and spring season than in winter season. Bacterial load was also dependent on fish size; larger fish had more bacterial content.
