明山水库总库容1.69亿 m~3,养鱼水面1万亩,是一座灌溉、防洪、养鱼等综合利用的大型水库。渔业经营30余年来,鱼产量不断提高,曾多年达到省定的亩产25kg的较高水平。以前存在的主要问题是,重视成鱼产量,忽视经济效益,其结果导致利润少,群众生活困难,偷炸鱼成风,资源没有得到很好开发利用,库区秩序混乱,成鱼产量和经济效益皆大幅度下降。1983年成鱼产量降至4.38万 kg,亏损5.75万元。为了充分利用水库渔业资源,提高经济效益,1988—1990年我们进行了渔业高产高效益配套技术研究。结果经济效益大幅度增长,年
The total storage capacity of Ming Shan Reservoir is 169 million m ~ 3, with 10,000 mu of aquaculture water surface. It is a large-scale reservoir with comprehensive utilization of irrigation, flood control and fish breeding. Over the past 30 years of fishery management, the output of fish has been continuously raised. It has attained a high level of 25kg per mu in the province for many years. The main problems that existed before were the emphasis on the production of adult fish and the neglect of economic benefits. As a result, their profits were low, their livelihood difficulties were deteriorated, the fish were blown into the wind, their resources were not well exploited, the order of the reservoir area was chaotic, and the fish production and economic benefits Are greatly reduced. Adult fish production in 1983 dropped to 43,800 kg, a loss of 57,500 yuan. In order to make full use of reservoir fishery resources and improve economic efficiency, we carried out research on high-yield and high-benefit fishery technologies from 1988 to 1990. As a result, the economic benefits have increased by a large margin
