AbstractThe species composition, spatial distribution and biomass of shrimps in the Biandantang Lake,Hubei province,were investigated by sampling with pop-net( 10m(2)) in the Autumn of 2002. The total of 44 287 individuals belonging to 6 species, 5 genera and 2 families,were collected from the 31 sampling sites. The dominant species were Macrobrachium nipponense, Caridina nilotic gracilipes and Neocaridina denticulate sinensis, which contributed 99.3% to the total. In terms of water depth, the lake was classified into 3 water-depth areas: shallow area(< 1.0m), medium-depth area(1.0-1.5 m) and deep area( > 1.5m). Based on the type and cover of aquatic vegetation, the lake was categorized into 4 habitat types: Vallisnerria spiralis habitat, Ceratophyllum, demersum habitat, Myriophyllum spicatum habitat, and naked habitat. For dominant shrimps, significant difference in density was not observed among 3 water-depth areas(ANCOV, P > 0.05); whereas, it was found among 4 habitat types(ANCOV, P < 0.01). Each of the dominant species preferred the Vallisnerria spiralis habitat. The density and the biomass of all shrimps in the lake were estimated to be 83.36 ind/m(2) and 3.97 g/m(2), respectively, of which C. nilotic gracilipes contributed 64.69 ind/m(2) and 1.53 g/m(2), M. nipponense 8.99 ind/m(2) and 2.09 g/m(2), and N. denticulate sinensis 8.61 ind/m(2) and 0.22 g/m(2).
