我国有水库86852座,其中小型水库84122座,数量众多。而小型水库的渔业生产水平普遍较低,未能充分发挥其渔产力。笔者对岳戈庄水库的生态渔业养殖技术进行了实践与探索。 1 水库概况岳戈庄水库位于诸城市东南部,建于1957年,是一座总库容为85万 m~3的小(二)型水库,兴利库容36万 m~3,死库容13万m~3,有效养鱼面积8hm~2(120亩),平均水深5.3m,最大水深8.2m。东西最大宽度200m,南北最大长度800m,大坝长300m。光热资源较差,无霜期201天,冰封期20～30天。浮游植物数量155万个/L, 生物量3.10 mg/L。浮游动物数量1580个/L,生物量2.80 mg/L。是一座狭长的丘陵型水库。
China has 86,852 reservoirs, of which 84,122 are small reservoirs, with a large number of them. Small-scale reservoirs, on the other hand, generally have low levels of fishery production and have not been able to fully exploit their fisheries productivity. The author of Yue Gezhuang Reservoir ecological fisheries farming practices and exploration. 1 Reservoir Overview Yue Gezhuang Reservoir is located in southeastern Zhucheng City, was built in 1957, is a small reservoir with a total capacity of 850,000 m ~ 3, Xingli storage capacity of 360,000 m 3, dead storage capacity of 130,000 m ~ 3, the effective fish area 8hm ~ 2 (120 acres), the average depth of 5.3m, the maximum depth of 8.2m. The maximum width of 200m, the maximum length of 800m from north to south, dam 300m. Light and heat resources are poor, frost-free period of 201 days, ice period of 20 to 30 days. The number of phytoplankton was 1.55 million / L and the biomass was 3.10 mg / L. The number of zooplankton was 1580 / L and the biomass was 2.80 mg / L. Is a narrow hilly reservoir.
