Structure of zooplankton community in Donghu Lake of Wuhan

Abstract

Abstract: The structure of zooplankton community in Donghu Lake of Wuhan was studied in 1991. The number of zooplankton at stations Ⅰ. Ⅱ and Ⅲ is respectively 122782, 70415 and 18184 individuals. L^-1, being increased with increasing eutrophication of water body, and the biomass is 8.639, 5.872 and 2.082 mg·L^-1 respectively. The frequency of large-sized crustacean (>1mm) is respectively 0.15, 0.30 and 0.41, and its body length is shortened with the increase of fish yield. Ecological factors affecting the structure of zooplankton community are discussed.

Key words: Zooplankton, Community structure, Size-frequency distribution, water use efficiency, chlorophyll fluorescenceSymbol characteristics, micro-sprinkling hose length and width, wheat, water characteristics, grain yield
