Species diversity of Protozoa in the Gahai Lake was studied based on “non-flooded petri dish method” and in vivo observation from October 2011 to January 2012. A total of 44 species including 1 unnamed species, belonging to 2 phyla, 5 classes, 153 orders, 28 families and 31 genera, were identified. Ciliophora was the dominant group and the number of species occupied 61.36% of the total. Sarcomastigophora with 17species occupied about 38.64% of the total. Analysis of diet of 44 Protozoa indicated that Bactivores-detritivores (B group) was the major group and Algivores (A group) was the second one, which consisted of 28 species and 10species, occupied 63.64% and 22.73%, respectively. Saprotrophs (S group) with 2 species was the least group. We concluded that the quantity of water in the Gahai Lake was worse in winter based on the functional-trophic group of Protozoa, and it needs further treatment and protection.
