南四湖是山东省淡水鱼类养殖基地,在发展大水面湖泊养鱼的同时,池塘养鱼在该地区发展的也很快。为了提高池塘养鱼的产量,提高经济效益和减轻劳动强度,必须从人工养鱼走向机械养鱼,为此省科委和省水产局于1988年给济宁市下达了池塘机械化养鱼技术推广项目,经过两年的工作,该地区的池塘养鱼机械化程度有了很大的提高。推广面积达2188亩,取得了平均亩产624.8公斤的成绩。现在已拥有各种养鱼机械3030.8瓩,平均每亩1.37瓩,其中有增氧机219台、498.8瓩;饲料加工机13台,498.8瓩;挖塘机11部,挖掘机1部,推土机1部,并有一批从4马力到130马力的运输机械。增氧机的使用,增加了放氧密度,一类塘亩放鱼种110—130公斤,1000—1200尾;二类塘亩放鱼种90—100公斤,1000尾以上;三
Nansi Lake is a freshwater fish breeding base in Shandong Province. In the process of developing large-scale water surface lakes, pond fish are also developing rapidly in this area. In order to improve the pond fish production, improve economic efficiency and reduce labor intensity, we must move from artificial fish to mechanical fish farming, for which the province Science and Technology Commission and the Provincial Bureau of Fisheries in 1988 issued to Jining City, pond mechanized fish farming technology promotion project After two years of work, the degree of mechanization of pond fish farming in the area has been greatly improved. To promote the area of 2188 acres, made an average of 624.8 kg per mu results. Now has a variety of fish machinery 3030.8 瓩, an average of 1.37 每 per mu, of which 219 aerators, 498.8 饲; 13 feed processing machines, 498.8 瓩; Digging machine 11, excavator 1, bulldozer 1 Ministry, and a group of transport machinery from 4 horsepower to 130 horsepower. The use of aerator increased the oxygen release density, a class of ponds to release fish species 110-130 kg, 1000-1200; class two acres of turtles 90-100 kg, more than 1000;
