湘西自治州的凤滩水库开展网箱养鱼始于1980年,经过十多年的试养、示范、推广,现已发展到1100只网箱(45亩),饲养品种有鲢、鳙、草、鲤、罗非鱼等,年总产量14.9万公斤,亩平4843公斤,经济效益显著。1990年7月,全国水产科技扶贫会议的专家代表,参观了这里的网箱养鱼现场,评价网箱养殖鲢、鳙鱼是一项低投入、中产出、高效益的养殖业。本文旨在总结十多年来的风滩水库网箱养殖鲢、鳙鱼经验的基础上,分析其经济效益,并对其前景提出一些粗浅看法。一、效益分析凤滩水库网箱养鱼,从试养到推广,几经周折,经营体制由全民、集体所有制的国家机关、团体经营,转为个体所有的
Fengtai Reservoir in Xiangxi Autonomous Prefecture began its cage fish culture in 1980. After more than ten years of trials, demonstrations and popularization, it has grown to 1,100 cages (45 acres) with varieties of silver carp, bighead carp, grass, Carp, tilapia and so on, the total output of 149,000 kilograms, mu 4,843 kilograms, significant economic benefits. July 1990, the National Aquatic Scientific and Technological Poverty Reduction Conference on behalf of experts visited the cage fish farming site here, the evaluation of cage culture silver carp, anchovy is a low input, middle output, high efficiency aquaculture. The purpose of this paper is to summarize the experience of breeding silver carp and bighead carp in the net cage of Fengtan Reservoir for more than ten years, and to analyze its economic benefits and provide some superficial opinions on its prospects. Benefit Analysis Fish ponds in Fengtan Reservoir are managed from trial to promotion. After several twists and turns, the operating system is operated by state organs and groups under the ownership of the whole people and collective ownership, and is transformed into individual ownership
