一、历史的回顾建国以来,浙江省兴建了大量水利工程,担负着防治自然灾害和提供水资源两项基本任务。目前有99座不同类型、坝型的大中型水库,宜养鱼面积100万亩以上。水库渔业是我国淡水养殖业的重要组成部分,具有“节地、节粮、节水、节能”的特点。当今我省水库渔业正从传统的粗放型生产进入到以水利工程学为基础、生态学管理为原则、强化渔业技术措施为手段的新阶段。 (一) “六五”期间我省水库渔业发展情况 1.渔业生产持续稳定发展。大中型水库已养面积由1980年的80万亩扩大到90万亩,鱼产量由1980年的4000吨提高到1985年的8600吨,年递增率为16.5％。
I. Historical Review Since the founding of the People’s Republic of China, a large number of water conservancy projects have been built in Zhejiang Province and are responsible for two basic tasks of preventing and controlling natural disasters and providing water resources. There are currently 99 different types of large and medium dam reservoirs, fish culture should be more than 100 acres. Reservoir fishery is an important part of China’s freshwater aquaculture industry, with “land, grain, water, energy saving” features. At present, reservoir fishery in our province is entering a new stage from the traditional extensive production to the principle of water conservancy engineering and ecological management, and the enhancement of fishery technical measures. (I) Development of reservoir fisheries in our province during the “Six Five-Year Plan” period 1. The fishery production has maintained a steady and steady development. The area of raised medium and large reservoirs has been expanded from 800,000 mu in 1980 to 900,000 mu. The fish production increased from 4,000 tons in 1980 to 8,600 tons in 1985, an annual increase rate of 16.5%.
