| 摘 要： | 白鲫是杂食性鱼类,其鱼种主要食物是有机物碎屑和浮游生物,其中包括一定数量的丝状藻类,如水绵等。应用P32放射性同位素进行示踪试验和鱼体放射自显影,证实白鲫鱼种可以摄食和消化利用水绵。在我们的试验条件下,白鲫取食水绵的摄食率(日摄食量占鱼体重量的百分比)为1.85-4.00%,对水绵的实际消化吸收率为48.49%。

| Abstract: | The White Crucian Carp (Carassius cnvieri T. et S.) is one of the omnivorous fishes, its fingerling feeds mainly on organic detritus and planktons, which include some filamentous algae such as Spiroyyra.A series of tracer experiments using P32 as a tagger and the radioautography had been carried out. The result presented here indicates that Spiroyyra can be ingested, digested and absorbed by the fingerliug of White Crucian Carp. Under conditions of our xperiment, the average feeding capacity of the fingerling of White Crucian Carp fed on Spirogyra is 1.85-4.00% (percentage of food consumed daily to body weight), and its digestive rate is 48.49%.
