Bacteriological And Physicochemical Assessment Of Aquaculture Freshwater Fish (Clarias Gariepinus And Oreochromis Niloticus) In Different Habitat Locations Using Small Scale Depuration System

ABSTRACT

Two freshwater fish samples (Claries gariepinus and Oreochromis nilolicus) were harvested from two different locations (MOUAU and Umugbalu fish farm). The fish samples were treated in constructed small scale depuration system. Bacterial quality of the fish samples, its habitat and UV treated water used for fish treatment during depuration were also investigated. Similarly, the physicochemical properties (pH, temperature, salinity, turbidity and dissolve oxygen) of the habitat (pond) were investigated. Furthermore, the initial fish weight before and after depuration were analysed. The total plate count (TPC) of the fish samples were determine and isolates characterized before and after depuration. TPC and other selected pathogenic bacteria in water and different fish organs differed significantly
