新安江电站的高坝尾水形成了坝下23公里长、14,000多亩水面的冷水区,水温常年在20℃以下(1986年1月至12月的月平均水温是10.9;10.0;10.0;11.4;12.8;12.513.6;14.4;15.9;17.0;16.7;13.9;),为发展网箱养鳟提供了优越自然条件。 1986年浙江省建德县水电局在新安江水电站坝下3公里处的建德县虹鳟养殖场进行了网箱培育虹鳟鱼种试验。网箱规格为2×2×1米~3,箱体网衣分为三级,一级箱采用16目聚乙烯网布制成;二级箱由3目无结节聚乙烯网片制成;三级箱由2×3聚乙烯丝编织成2目网片制成。均为六面体封闭式。箱留一边不缝作投饵孔。毛竹框架,漂
The tailrace of the high dam of Xin’anjiang Power Station formed a 23-kilometer-long, 14,000-mu cold water area below the dam, with annual water temperatures below 20 ° C (January-December 1986 average monthly temperature was 10.9; 10.0; 10.0; 11.4 ; 12.8; 12.513.6; 14.4; 15.9; 17.0; 16.7; 13.9;) provided excellent natural conditions for the development of caged trout. In 1986, the Jiande County Hydropower Bureau of Zhejiang Province conducted a cage-cultivating rainbow trout test in Jiande County rainbow trout farm 3 km below the Xin’anjiang Hydropower Station dam. Cage specifications for 2 × 2 × 1 m ~ 3, the box is divided into three network clothing, a box with 16 mesh polyethylene mesh made of; two boxes from 3 mesh nodules made of polyethylene mesh ; Three boxes made of 2 × 3 polyethylene mesh woven into 2 mesh mesh. Are hexahedral closed. Not leave the box for the bait hole. Bamboo frame, drift
