AB  - A study was carried on the effect of nickel exposure on the miroflora of the skin and gut of African catfish,<I> Clarias gariepinus</I>. <I> C. gariepinus</I> of different stages was applied with nickel and monitored every 24 h over a period of 672 h in wooden vats under a laboratory condition. Eleven adult samples, thirty six post juvenile and thirty one juvenile samples were analyzed for the isolation of microflora using biochemical test. Both gram +ve and gram -ve bacteria were isolated. The gram -ve bacteria isolated were mainly rods and members of the Family Enterobacteriaceae including <I>Proteus </I>and<I> Serratia</I>. These species were more widely distributed in and more frequently isolated from the gut regions than the gram +ve bacteria which were represented by <I>Streptococcus</I> and <I>Staphylococcus</I> species. <I>Proteus</I> species and <I>Streptococcus </I>species isolated from the gut extracts were also found in the skin region. <I>Bacillus</I> species and <I>Pseudomonas </I>species were also found in both the skin and gut regions of the fish. The number and types of microbes in the skin and gut regions are similar.
