摘　　要：为探索山区稻田规模化精养鱼类的可行性,以体长3～6cm的瓯江彩鲤为放养对象,在浙西山区景宁县15个乡镇的512hm2稻田里进行了生产性试验.放养密度3000～9000尾.hm2,经200 d左右精心饲养,收获总商品鱼5.76×105 kg,每公顷平均产鱼1 125 kg,平均毛利超过15000元.据此,并结合山区稻田的基本特点及其养鱼现状,探讨了适用于山区稻田养鱼规模化开发的田块、品种、规格、密度和日常管理等精养鱼类的技术环节,提出了技术推广与产品营销的配套措施,为山区稻田养鱼的规模化发展提供参考.In order to explore feasibility of scaled intensive fish culture in mountain paddy-field,taking color common carp（Cypinussarpio.var.color.） with average body length of 3～6 cm as the case study,we investigate the productivity in paddy-field of 512 hm2 over 15 villages and towns in Jingning County,western Zhejiang Province.Under the condition of 3 000～9 000 ind.fingerlings stocked per hm2 and comprehensive management measures taken,the marked effects of total fish production of 576 000 kg,average production of 1 125 kg and gross profit of over 15 000（RMB） per hm2 are achieved after about 200 d meticulous culturing.Combining the results with major characteristics of mountain area and the status in quo of fish culturing,the lings culturing is found to be applicable in mountain paddy-fields with suitable size,proper stocking density and good daily management.The culturing techniques are analyzed and discussed,which provides practical references to developing paddy-field fish culturing tactics in mountain areas.
