Abstract: – The bio-indices of bacteria load in water and mangrove oyster (crassostrea gasar) tissues of Woji/Trans-Amadi creek, Port Harcourt, Nigeria were studied between January and June, 2019. Water and oyster (Crassostrea gasar) samples were collected from three stations and analysed for bacteria using standard method. The data obtained were subjected to SPSS software version 20 for descriptive and inferential statistics using one-way analysis of variance and Duncan multiple range test. The results obtained showed that the water and the oyster samples contained 11 and 12 species of bacteria respectively with oyster samples containing more bacteria counts than the water. Bacteria counts in station 2 for both samples differed significantly from stations 1 and 3 at p<0.05. Some of the species of bacteria identified were Escherichia coli, Staphylococcus aureus, Salmonella species, Enterococci sp, Klebsiella. Shannon-Wienner index and other indices showed that the water and oyster tissues were heavily (0.928±0.01) and moderately (1.044±0.09) polluted microbially. The results suggest that Woji/Trans-Amadi creek is moderately to heavily polluted microbially hence adequate measure should be taken to prevent further discharge of organic wastes into the creek.
