EFFECT OFIPOMOEA AQUATICAFLOATING-BED ON THE ROTIFER COMMUNITY STRUCTURE IN GRASS CARP POND
摘要
Abstract
We studied the effect ofIpomoea aqucaticafloating-bed on the rotifer community structure in grass carp pond from June to September in 2011. The density and biomass of rotifer, the key environmental factors in floating-bed and non-floating-bed ponds were tested. The densities of rotifer in the floating-bed pond and non-floating-bed pond were 1892 ind./L and 2255 ind./L, respectively. The densities in these two kinds of ponds were significantly different (P<0.01). The biomasses of rotifer in the floating-bed pond and non-floating-bed pond were 1.535 and 1.405 mg/L, re-spectively. The biomasses in these two kinds of ponds were significantly different (P>0.05). During the experiment, 38 species belonging to 7 families, 14 genera was detected in rotifers. Thirty-six species were detected in the floating-bed ponds rotifers, and 28 species were detected in non-floating-bed ponds. Dominant species of the two types of ponds were essentially similar, including Brachionus calyciflorus,Brachionus diversicornis,Anuraeopsis fissa,Trichocerca Pusila andPolyarthradolichoptera. The results showed thatIpomoea aquatica floating-bed could promote the number of rotifer species significantly, improve the rotifer diversity and evenness, and inhibit the rotifers miniaturization effec-tively.关键词
