    Bacteria are abundant and form floccule by agglutination in fertile fish ponds, most of them can be fed by freshwater animals. However, their roles as fish feed and nutrition remain obscure. The liquid scintillation technique with ~(14)C was used to investigate the digestion and absorption rate of bacteria floccules Results obtained were 45.1% and 81.4% by Hypophthalmichthys molitrix and Oreochromis niloticus respectively. Beef extractpeptone, leaf extract of Eichhornia sp. and organic residue of pond as organic source were used to culture bacteria. The floccules thus analysed contained 50.1%, 36.5% and 36.7% crude protein respectively and all necessary amino acids for fish larva growth. Floccules were employed to feed fish larva successfully. After 13 days of feeding, the wight of H. molitrix (338. lmg) and O. niloticus (252.7mg) increased by 67.3%and 104.1% respectively. The above results show the satisfactory effects of fluccole as fish feed and confirm its role as an important producer in pond ecosystem. They also suggest that apart from the generally conception of phytoplankton-zooplankton-fish food chain, there may be other processes of organic mass flow beginning from bacterium such as bacterium-protozoan-fish, bacterium-zooplankton-fish and bacterium-fish in pond ecosystem, which are ignored at present

    本文叙述以放射性核素~(14)C为指标,测定滤食性鱼类对饵料消化吸收率的方法。用此方法测得的白鲢和罗非鱼对细菌絮凝体的消化吸收率平均分别为45.1%和81.4%。用不同培养基培养出的细菌絮凝体的蛋白质含量在36.5~50.1%之间,而且均含有对鱼类生长必需的氨基酸。平均体重为338.1mg的白鲢鱼种和252.7mg的罗非鱼鱼种,用细菌絮凝体饲养13天后平均增重率为67.3%和104.1%。结果表明,水生细菌对滤食性鱼类具有良好的饵料效果;且水生细菌不仅是水体生态系物质循环过程中的分解者,而且它还通过食物链发挥着重要的生产者的作用。
