中文摘要：
采用初级产量法、浮游动物与底栖动物现存量法，估算出长春南湖水体的潜在鱼产力为46564kgWW／a。根据秋季收获量与春季投苗量的差值，得到南湖水体的实际鱼产力为14527kgWW／a，不足潜在鱼产力的1／3。从湖泊鱼类放养的角度出发．建议适当增加投苗量。
英文摘要：
Using primary production method, zooplankton standing crop method, and benthos standing crop method, the fishery potential of the Nanhu Lake waterbody in Changehun was estimated as 46 564 kgWW/a. Based on the difference between harvest in autumn and input in spring, the practical fishery production of the Nanhu Lake waterbody was 14 527 kgWW/a which was less than 1/3 of the fishery potential. In terms of fishery culture in lake, the fish input amount can be properly increased.
