One of the greatest problems that the world is facing today is of environmental pollution. Increasing with every passing year and causing grave and irreparable damage to the environment .potentially harmful substances e.g. pesticides, heavy metals and hydrocarbons are often released into the aquatic environment. When large quantities of pollutants are released in water there may be immediate impact as measured by large scale. Sudden mortalities of fishes and other aquatic organisms. Lower levels of discharge may results in accumulation of the pollutants in aquatic organism. The end results which may occur long after the pollutants have passed through the aquatic environment include reduced metabolism, damage of skin and gills. Current study shows that some of the diseases caused by virus, pseudomonas, flavobacterium resulted from generally adverse water quality i.e., higher than usual quantities of organic material, oxygen depletion, change in pH values and enhanced microbial populations some infections with Serratia and Yesinia may also well reflected contamination of water with domestic sewage e.g. leaking septic tank.
