Duplicate composite vertical samples of zooplankton were collected from the water column using 50μm plankton net of 30 cm diameter and preserved with 5% formalin prior to identification in the laboratory. Water quality parameters were also measured in-situ. Cyclopoid copepods (64.7%) dominated the zooplankton community while Rotifers (1.7%) were the least abundant in the lake. A total of 20 zooplankton species were identified under the taxa 9 Rotifer, 6 Cladoceran, 4 Cyclopoid and 1 Calanoid. Multiple comparisons by Tukey test showed no significant difference in zooplankton density among the stations (p>0.05). The highest values of water quality parameters recorded were turbidity 70.52 mgL-1 , conductivity 158.72 μS/cm, temperature 27.38 o C, Dissolved Oxygen 5.25 mgL-1 and pH 8.06, with corresponding lowest values of 11.09 mgL-1 , 93.26 μS/cm, 25.74 o C, 4.35 mgL-1 and 7.41. The observations from the study could be linked to the habitat degradation and pollution causing changes in the zooplankton community in Lake Victoria.enUniversity of EldoretArticle
