封闭式内循环水产养殖方式已成为全球性的发展趋势,是符合国情实用高效的养殖模式,也是我国水产养殖业重要的研究方向。文中在实践的基础上探索了一种操作简便、经济适用、预防疾病、高产高效的新型生态型内循环养殖模式。实验总规模1440m2,分别为4个养殖系统,养殖点带石斑鱼(Epinephelus malabaricas),成活率93.71%,单位面积年产量30kg/m2;当个体规格达到100g/尾以上时,月死亡率0.01%左右;每公斤商品鱼耗电5.67千瓦时。是一个节能并高效预防疾病发生的生态清洁型养殖系统。
Enclosed internal circulation aquaculture has become a global trend of development, is in line with the national conditions and practical and efficient farming model, but also China’s aquaculture industry an important research direction. Based on the practice, this paper explores a new type of eco-type internal circulation breeding mode that is easy to operate, economical, disease prevention, high yield and high efficiency. The experimental scale of 1440m2, respectively, four farming systems, breeding point with grouper (Epinephelus malabaricas), the survival rate of 93.71%, the annual output of 30kg / m2 per unit area; when the individual specifications reached 100g / tail above, the monthly mortality rate of 0.01 %; Electricity consumption per kilogram of fish 5.67 kWh. It is an ecologically-clean farming system that saves energy and effectively prevents disease from occurring.
