摘要:
利用浮游生物计数法和黑白瓶测氧法对万佛湖的初级生产力进行测定,并以此对万佛湖鲢、鳙鱼产量进行测算。结果表明,浮游生物计数法评估万佛湖鲢、鳙鱼产力达1 100~2 000 t,黑白瓶法评估鱼产力为2 200 t。比万佛湖实际产量高很多,说明水库的鱼产力尚未达到上限。

Abstract:
By using plankton counts and black and white bottle oxygen measuring methods, we determined primary productivity and estimated fish products of silver carp and bighead carp in Wanfo Lake. The results showed that the productivity of silver carp and bighead carp in Wanfo Lake could reach to 1 100 ~ 2 000 t by plankton counting assessment, and the fish production was 2 200 t when assessed by black and white bottle method. The assessment results are much higher than the actual production of this lake, indicating that the reservoir fish production does not yet reach the upper limit.
Key words:  Wanfo Lake  plankton  primary productivity  fish productivity
