随着水利事业的发展,水庫渔业也逐漸开展起来。目前有許多水庫大都是人工投放魚种,經营比較粗放。由于水庫面积大,投放的魚种很多,因此,苗种供应問題急待解决。过去响洪甸、佛子岭、梅山等水庫都由长江采購魚苗,經池塘培养成魚种,再放入水庫,不仅投資很大,而且苗种規格小(一寸左右)、質量差,放养成活率低,严重地影响到水域資源的扩大再生产。响洪甸水庫自1959年开始渔业利用,放养的花白鰱一般都生长发育的很好。据調查,三至四龄的白鰱一般体长七十至八十厘
With the development of water conservancy, reservoir fishery also gradually started. At present, many reservoirs are mostly man-made species of fish, operating more extensive. Due to the large reservoir area, there are many species of fish put on the farm, therefore, the supply of seedlings is in urgent need of solution. In the past, floods from Hongdian, Fuziling, Meishan and other reservoirs were purchased from the Yangtze River fry, the ponds cultivated into fish species, and then into the reservoir, not only a large investment, but also small seed size (about an inch), poor quality, stocking survival rate Low, seriously affecting the expanded reproduction of water resources. Xiang Hongdian reservoir fisheries since 1959, the stocking of silver carp growth and development are generally good. According to the survey, silver carp of three to four age is generally 70 to 80% body length
