所谓“半咸水养鱼”,就是指用含盐量超过0.05%的水养鱼。1984年,我所选择了我市独树沟乡牛营子村吕学松、陈德满两户在沿海滩涂盐碱地上开发的26.5亩鱼塘进行了半咸水养鱼试验,当年养出成鱼16,365斤,平均亩产617斤,亩产值729.50元。现将有关半咸水养鱼方法介绍如下:1.鱼塘修建方法:要求半咸水鱼塘修建在高盐度的海岸、湖区。在修建鱼塘时,首先要考虑合适的修建区域、淡水水源供给量、海潮正常淹没的高度等,然后再确定适宜的修建位置。标准鱼塘的形状,一般东西长,南北宽,要求水深2~2.5米,堤坎高度高于海潮最大冲击点,坎基、顶要夯实,以防海潮淹没。
The so-called “brackish water fish” refers to the water with more than 0.05% salt water fish. In 1984, I chose the Lü Xuesong and Chen De-Man, Niuyingzi Village, Dushugou Township in our city to conduct brackish water fish culture test on 26.5 mu fish ponds developed on the coastal saline land of saline land. In the same year, 16,365 jin of adult fish were raised, Average yield of 617 kg, 729.50 yuan per mu. The method of fish farming for brackish water is as follows: 1. Construction of fish ponds: Half-saltwater fish ponds are required to be built on high salinity coasts and lakes. When building a fish pond, first consider the appropriate construction area, the supply of fresh water, the normal submergence of the tide, etc., and then determine the appropriate construction site. Standard fish pond shape, the general east-west length, north-south width, depth of 2 to 2.5 meters, dike higher than the maximum impact point of the tide, Camry, the top to be compacted to prevent submergence of the tide.
