河坝的建立不仅可利用水力发电,而且为发展网箱养鱼提供了良好的场所。实践证明,河坝上游发展网箱养鱼具有得天独厚的优势,一是河床水位深,水面宽,形成了一个较大的缓冲区,有利于设置网箱;二是河坝上游淤泥沉积,水流平缓,水草丛生繁茂,可为网箱养鱼提供优质饵料。在河坝上游开展网箱养鱼只要管理得当,每只网箱投放大规格鱼种600—1000尾,可产成鱼600—1000kg,获纯利1000—1500元,达到高产、高教的目的。据调查,我省丘陵山区河坝星罗棋布,但利用进行网箱养鱼的为数甚微,绝大部分任其
The establishment of dams not only makes use of hydroelectric power, but also provides a good place for the development of cage fish culture. Practice has proved that the upper reaches of the river dam development of fish culture cage has a unique advantage, one river bed deep, wide water surface, forming a larger buffer zone, which is conducive to the installation of cages; second dam upstream silt deposition, water flow gentle , Lush vegetation, can provide high-quality cage fish food. Cage aquaculture in the upper reaches of the dam as long as managed properly, each cage put large-scale species 600-1000 tail, can produce fish 600-1000kg, net profit of 1000-1500 yuan, to achieve high yield, higher education purposes. According to the survey, the dam in the hilly mountainous areas of our province is dotted with cloth, but the use of cage fish farming is very small, most of them
