山东省肥城市由于煤矿井下采煤,形成煤矿塌陷地5.8万亩,其中涝洼沼泽2.3万亩,水域0.9万亩,成为水产养殖开发的新领域。该市于1988年开始探讨塌陷地养鱼,现已开发养殖水面1.1万亩,年产商品鱼295万公斤,创产值1700余万元。石横镇新胜渔场360亩池塘,年均亩产逾千公斤,产值6000余元,获得了高产高效益,并安置了劳力,改善了塌陷地的生态环境。现将其主要高产技术措施介绍如下: 一、主要养殖条件 煤矿塌陷地水域大者200～300亩,乃至上千亩,小者数十亩。同地下水相贯通,水位与地下水临界水位持平,距地面0.5～2米,呈封闭小区,成为连片的地下“小型水库”。养鱼用水的水源,有地表径流
As a result of underground coal mining in Feicheng City, Shandong Province, 58,000 mu of coal mine collapsed land was formed, of which 23,000 were flooded and swollen, with an area of 9,000 mu and became a new area for aquaculture development. The city began to explore the collapse of fish farming in 1988, has now developed breeding waters 11000 acres, with an annual output of 2.95 million kilograms of fish products, a production value of 1700 million yuan. Shisheng Town, Xinsheng fishing grounds 360 acres of ponds, the average annual output of more than 1,000 kg per mu, the output value of 6,000 yuan, access to high yield and high efficiency, and the placement of labor, improved subsidence of the ecological environment. Now its main high-yielding technical measures are as follows: First, the main breeding conditions Coal mine collapse area of the larger 200 to 300 acres, and even over a thousand acres, a small number of mu. With the groundwater phase through, the water level and the critical level of groundwater flat, 0.5 to 2 meters from the ground, was closed area, a contiguous underground “small reservoir.” Fish water supply, surface runoff
