湘阴县共有可利用水面54.3万亩。其中大水面46.5万亩,占可利用水面的82.3％。外湖41万亩,1000亩以上的内湖、哑河、水库22处5.5万亩。过去这些水面只捕不养或人放天养,基本上处于荒芜状态。1986年以来,我县努力探讨开发利用大中型水域的技术方法和途径,共开发大中型水域近10万亩。累计增产鲜鱼4915.9吨,名特水产品217.6吨,新增产值2670万元,增加盈利1035万元,单产比开发前提高13.2倍。六年来,我们摸索出了五种不同形式的技术开发模式: 一、外湖低坝型。选择外湖条件适宜的地点,以土
Xiangyin County, a total of 54.3 acres of water available. Among them, 465,000 mu are large surface water, accounting for 82.3% of available water surface. 410000 acres of the outer lake, more than 1000 acres of the lake, dumb river, reservoir 55000 acres. In the past, these water surfaces were not caught or were kept in the sky, basically in a barren state. Since 1986, our county has made great efforts to explore technical methods and approaches for developing and utilizing large and medium-sized waters, and has developed nearly 100,000 mu of medium and large-sized waters. The cumulative increase of 4915.9 tons of fresh fish, famous special aquatic products 217.6 tons, the new output value 26.7 million yuan, an increase of 10.35 million yuan in profits, higher than the pre-development 13.2 times. In the past six years, we have explored five different types of technology development models: First, the low lake dam type. Select the appropriate conditions of Lake conditions to soil
