汉川县汈汊养殖场运用科学手段,提高湖区水域的利用率。他们采取的工程措施有: 1.开发荒汊。将过去的荒汊围起来养鱼,鱼产量提高了5.4倍。 2.在荒滩上建造精养鱼池、鱼种池。使产量达到250—400公斤/亩。 3.对大水面采取半堤半箔切块分格放养。即带水筑起1.5米高的堤,堤上插2米高的箔,冬春放水露堤,夏季进行扩湖。 4.以鱼为主,配套发展多种经营。从水底到水面,从水域到堤埂,配套饲养鸡、鸭、鹅、猪;实现 Hanchuan County 汈 汊 farms use scientific means to improve the utilization of the lake waters. The engineering measures they take are: 1. Development of wasteland. Surrounded by barren fish farming, fish production increased by 5.4 times. 2. Built on the wasteland fish ponds, fish ponds. The output reached 250-400 kg / mu. 3. The water surface to take half-embankment half-foil cut pieces of stocking. That is, a 1.5-meter-high embankment is built with water and a 2-meter-high foil is inserted in the embankment. 4. Fish-based, supporting the development of a variety of business. From the bottom to the surface, from the water to the embankment, supporting breeding chickens, ducks, geese, pigs; to achieve
