Abstract
There has been a significant increase in the rate of water pollution in the Niger Delta, Nigeria, which has been associated with indiscriminate wastewater disposal. The increased rate of water pollution owing to human perturbations poses an increased hazard to humans and the environment. This paper is aimed at understanding the status of Qua Iboe River Estuary through evaluation of the macro-benthic invertebrate’s diversity and abundance using indices such as the biotic index. Macro-invertebrates were collected and analyzed monthly at five different stations across the study area using standard procedure. The dominant phylum was mollusca which were represented by gastropoda while the least abundance was Annelida represented by Oligochaeta.Ecological indices such as, Shannon, Simpson and equitability indices were higher in station 1 and station 3 when compared to other stations. Species dominance was low in all the stations throughout the study. The results obtained from the family biotic index (FBI) showed that the water quality ratings across the stations were fairly poor to good, which is an indication of significant organic pollution. In the light of this study, awareness should be created by concerned stakeholders in educating the public on the ills and detrimental effects of water pollution.
