轮虫是淡水生态系统中重要的生态类群之一。它能摄食一些不能被鱼、蟹直接利用的细菌和碎屑 ,进而转化为能被鱼类利用的饵料。轮虫繁殖速度和周转较快 ,在浮游生物量中占有很高的份额 ,最高可达 30 % ,在食物链中具有重要地位 (王家楫 ,196 1;黄祥飞 ,1985;Nogrady ,199
Rotifera is one of the important ecological groups in freshwater ecosystems. It can ingest some bacteria and debris that can not be directly used by fish and crabs, which can then be converted into fish that can be used by fish. Rotifera reproduce faster and turnover, accounting for a high share of plankton, up to 30%, has an important position in the food chain (Wang Jiayi, 196 1; Huang Xiangfei, 1985; Nogrady, 199
