中国水库放养鱼的种类、食性以及可利用的天然饵料生物决定了半精养渔业是水库渔业的主要模式。水库半精养有中、小型水库、水库库汊、网拦、网围、网箱养鱼等多种形式。其产量与肥料、饲料的投入有直接关系。最大限度地利用天然饵料,并辅以补充性人工饲料,可实现高产高效。本文以水库鱼类的营养和饲料利用为基础,论述半精养水库渔业的理论和实用技术,并提出尚须研究的问题,以推进半精养水库渔业的发展。
The species, feeding habits and availability of natural food organisms in China’s reservoirs determine that semi-intensive fisheries are the main mode of reservoir fisheries. Reservoir semi-intensive medium and small reservoirs, reservoirs 汊, net bar, net Wai, net cage fish and other forms. Its output and fertilizer, feed has a direct relationship. Maximize productivity and efficiency by maximizing the use of natural feed supplemented with supplemental artificial diets. Based on the nutrition and feed utilization of reservoir fish, this paper discusses the theory and practical technology of fishery in semi-intensive reservoirs, and puts forward the problems that must be studied to promote the development of fishery in semi-intensive reservoirs.
