小型水库,具有水利、水电、养鱼等多种经营的作用,分为小Ⅰ型水库和小Ⅱ型水库两种。库容量100万至1000万立方米的为小Ⅰ型水库;库容量10万至100万立方米的为小Ⅱ型水库。我省共有小型水库11233座,1053192亩;可用于养鱼的小型水库有11133座,787163亩;而现在已经养鱼的只有9955座,651426亩。产量每亩从几公斤到一百多公斤不等,因此,发展小型水库养鱼具有十分重要的意义。现将小型水库养鱼的技术问题介绍如下:
Small reservoirs, with water conservancy, hydropower, fish and other operating role, divided into two small reservoirs and small reservoirs. The reservoir capacity of 1 million to 10 million cubic meters for small Ⅰ reservoir; reservoir capacity of 100,000 to 1 million cubic meters of small Ⅱ reservoir. There are a total of 11,233 small reservoirs and 1,053,192 mu of land in our province. There are 11,133 small and medium-sized reservoirs available for fish farming, with 787,163 mu. There are now only 9,955 and 651,426 mu of fish farmed. Yield per acre from a few kilograms to more than one hundred kilograms, therefore, the development of small-scale reservoir fish culture is of great significance. The technical problems of fish farming in small reservoirs are as follows:
