The study revealed spatio-temporal variations in zooplankton distribution and the factors influencing their distribution, abundance and composition. Factors affecting zooplankton density, biomass and distribution in Shirat Bay were found to include food condition, predation, temperature, wind, light and transparency. There was significant correlation between zooplankton abundance and the bacillariophytes (r = 0.9454,n=13,p<0.0001),Rotifera biomass and cyanophytes (r=08264, n =13,p<0.0001)there was a significant association between abundance of fish and zooplankton (Matel test: Standard normal Variate g(1,1000)=7.0834, p=0.009,r=0405, and abundance of haplochromines and zooplankton (g 1,1000) = 6.348, p=0.001,r = 0.888). also the linear correlation analysis revealed significant correlation between temperature and number of ovigerous female copepod (r= -05585, n=13, p=0.0473). three groups of zooplankton were recorded namely, Copepoda, Rotifera, and Cladocera. A total of 44 species were recorded, Rotifera showed highest diversity index (H’) of 2.321. Copepoda was the most important group in terms of abundance and biomass among them cyclopoid copepod dominated the zooplankton community throughout the study period.
