RELATIONSHIP BETWEEN BACTERIA ASSOCIATED WITH FISH POND SEDIMENT, WATER AND THE FISH

Among the bacterial strains isolated from fish pond water, sediment and fish using the enrichment method, the predominant ones were; in water sample Aeromonas, Streptococcus, Flavobacterium and Bacillus species while in sediment were Vibrio and Flavobacterium species, whereas that of the fish body surface (Tilapia zilli) include Aeromonas and Pseudomonas. Isolates from the body organs include Pseudomonas, Vibrio species, and Aeromonas were the most frequently occurring bacterial genera while Pseudomonas and Streptococcus species were the most frequently occurring bacteria genera in the gills.
