Monthly samples of zooplankton and surface water for physico-chemical parameters were collected at high tides according to standard methods. The plankton parameters studied were species composition, species diversity, abundance and occurrence. A total of 32 species from three taxa of zooplankton were identified. Copepods dominated the zooplankton (92.52%). The abundance of zooplankton did not vary significantly in the stations (2>1>3>4>5). There were slight fluctuations in the measured physico-chemical parameters. The results indicated the characteristic species and distribution of zooplankton in Elechi Creek during the dry months. Also, it provided information on the influence of some physico-chemical parameters on the zooplankton abundance. The presence of dominant copepods and high level of phosphate indicated an environment under stress and organic pollution. 收起
