| 摘 要： | 分析测定了主养鲢鳙非鲫高产池塘浮游植物初级生产力的垂直、周日、周年变化及其与主要生态因素、鱼产量水平的关系。探讨了初级生产力在能量转化中的生态学效率:毛初级生产力对太阳辐射能的利用率为0.84％—1.64％;鲢鳙非鲫净产量对浮游植物净产量的直接利用率为8.46％—15.56％;太阳能转化为成产量的生态学效率为0.058％—0.156％。

| Abstract: | The primary productivity by phytoplankton was determind durimg 1979-1981 for fishponds with the silver carp,bighead and tilapia as the major culture species. Tests were made on the vertical ,diel and seasonal changes in primary productivity in relation to major ecological factors and overall fish yield with the mean daily O2 production ranged from 3. 0 to 28. 9 gO2. m- 2d-1. The daily gross oxygen production usually exceeded oxygen, respiration The annual oxygen production was 2567-4197 gO2. m 2d-1.Monthly ... |
