| 摘 要： | 温杖子水库按养鱼水面单位面积承受２２００ｋｇ／ｈａ网箱鱼的负载量设置网箱，建立以网箱养鱼为重要环节的水库新型渔业生产结构体系。三年中，水库水面鱼产量（含网箱鱼产量）由１４５．５ｋｇ／ｈａ上升到２６６．７１ｋｇ／ｈａ，年总产量增长１８．３倍；渔业投入资金年利润率达７１．９％；网箱养鱼的投入总能量转换效率提高了６．０３－６．３６％。合理开发和保护了水库渔业资源，促进了温杖子水库渔业的高速增产。

| Abstract: | This article mainly expounds the issue of raising the total fishery productionby fish culture in the cage with pellets in Wenzhangzi reservoir. In this experiment, the finalfish loading in water area was designed according to 2, 200kg/ha, and a new structure systemof fishery production with fish culture in the cage as a key link was established' Within threeyears period, the fish crop has risen from 145. skg/ha to 2, 667. 1kg/ha (including the fishcrop in the cage), the total fish yield has increassed by 18. 3 times, the annual interest rateof the investment has reached 71. 9%, and the convertion ratio of energy investment hasgone up as high as 6. 03-6. 36 %. The system not only has greatly promoted the fishery pro duction, but also has rationally exploited and protected the fishery resources in the reser voir. |
