采用土拦库湾培育鱼种是解决水库养鱼所需鱼种的一种有效途径之一。现将土拦库湾培育鱼种技术的主要环节简介如下: 一、培育鱼种土拦库湾的选择:一般用作培育鱼种的库湾应选择库湾出口小,内部宽阔、库底平坦、底质好,这样的库湾建坝工程小,便于施工,且建成后可利用的面积大;另一方面要选择库形开阔、周围山头低,阳光充足,集雨面积较小,来水量不大,这样有利于培肥水质,和建筑拦鱼坝。拦截库湾的面积因饲养鱼种的规格不同,而选择不同的面积。一般用作
The use of earth barricades to cultivate fish species is one of the effective ways to solve the fish species required for fish culture in reservoirs. Brief introduction of the main links of technology for cultivating fingerlings in earth-holding bay is as follows: 1. Selection of fish-breeding land for sheltering bays: The bay which is generally used for cultivating fish species should have a small outlet of the bay, wide interior and a flat bottom , A good substrate, such a reservoir Bay dam project is small, easy construction, and after the completion of the available area is large; on the other hand to choose the open shape of the reservoir, the surrounding hills low, sunny, catchment area smaller, water Not big, this is conducive to fertilizing water quality, and building barrage dam. The area of the interception bay is different because of the different specifications of the breeding fish species. Generally used
