许多水库 ,由于集雨面积大 ,终年都有少量的余水排出 ,尤以 6— 9月鱼的黄金生产季节更甚。将这些水资源充分利用起来 ,进行池塘微流水养鱼 ,无疑是高产高效的重要途径之一。重庆永川上游水库在这方面作了有益尝试 ,将水库排出的水引入坝下池塘进行微流水养鲫鱼 ,经 2 10天 ,获 Many reservoirs, due to the large catchment area, have a small amount of residual water discharged throughout the year, especially during the September-September gold production season. Make full use of these water resources for pond microfluidic fish farming is undoubtedly one of the important ways of high yield and efficiency. The upstream reservoir of Yongchuan in Chongqing made a useful attempt in this respect. The discharged water from the reservoir was introduced into the pond under the dam for feeding the crucian carp in microfluid. After 2 10 days,
