我县地处岷江中游,县内一江四河,三条中型渠堰,支斗毛渠纵横交错,水利资源比较丰富,发展渔业生产的条件较好。1984年,我们针对上述情况,开展了渠道金属网箱养鱼试验。经过几年摸索,取得较好的效益。1986年,全县渠道金属网箱发展到62只,面积4626平方米,共放养鱼种1.735万公斤,虽受前期低温水枯和后期水深等诸不利条件的影响,年底仍产鲤鱼15万公斤,获利26万元;折合亩产2.16万公斤,利润3.8万元。渠道金属网箱养鱼的成功,带动了其它形式的集约化养鱼的发展。1986年,全县还发展高密度流水养鱼池
My county is located in the middle reaches of the Minjiang River, the county one river and four rivers, three medium-sized drainage weir, bucket vertical and horizontal branches staggered, water resources are abundant, the conditions for the development of fishery production is better. In 1984, in response to the above situation, we conducted a trial of channel cage fish culture. After several years of exploration, obtain better benefits. In 1986, the county’s network of metal cages developed to 62, an area of 4626 square meters, a total of 173500 kilograms of fish stocks, although the early low temperature water and water depth and other unfavorable conditions, the end still produce carp 150,000 kg , Profit 260,000 yuan; equivalent to 21,600 kilograms per mu, profit 38,000 yuan. The success of channel metal cage fish culture has led to the development of other forms of intensive fish farming. In 1986, the county also developed high-density water fish ponds
