近年来,随着我省小流域治理工作的加强,拦河坝数量越来越多,形成了大面积的天然水体,这些河道水体大都常年流水,水质清新富营养,多数没有工业污染,如果合理利用这些水体,将是山区渔业发展的一种新模式。具体措施如下:一、养鱼河道的选择根据养殖鱼类的生理特点和对水体环境的要求,所选河道应符合以下条件:1.水质清新肥沃,天然饵料丰富。2.水深适宜,最好在1米以上,水位稳定,流速缓慢。3.河水没有工业污染或轻度污染,在养鱼适宜范围之
In recent years, with the strengthening of small watershed management in our province, more and more barrages have formed a large area of natural water bodies. Most of these river water bodies are flowing all the year round, with fresh and eutrophic water quality and most of them without industrial pollution. If these are reasonably utilized Water body will be a new model for the development of mountain fisheries. Specific measures are as follows: First, the choice of fish farming According to the physiological characteristics of farmed fish and water environment requirements, the selected river should meet the following conditions: 1. Fresh and fertile water, natural food rich. 2. Suitable depth, preferably at 1 meter above the water level is stable, the flow rate is slow. 3. There is no industrial pollution or light pollution in the river, in the appropriate range of fish
