摘要
为了有效突破我国北方海域冬季网箱养殖品种少和产业发展缓慢的局面,通过陆海接力养殖模式,开展了云纹石斑鱼(Epinephelus moara)的网箱陆海接力养殖试验。结果显示:在莱州明波网箱基地选用的平均个体重量225 g的大规格云纹石斑鱼鱼苗,经过2个月的网箱接力养殖,个体平均重量达到350 g,平均单尾月增重62.5 g,成活率92.02%;在连云港众利网箱基地选用的个体平均重量152 g大规格云纹石斑鱼,经过4个月的网箱接力养殖,个体平均重量增加到425 g,平均单尾月增重68.25 g,养殖成活率达96.00%。石斑鱼的网箱养殖与工厂化循环水养殖相比,平均月增重速度提高54.6%～68.9%。
in order to effectively break through the waters of the north china winter aquaculture species less in cage culture and the slow development of industry, by land and sea relay farming model to carry out the Epinephelus moara cages land and sea relay breeding test. Results show that： selecting average individual weight of 225 g large-sized the Epinephelus moara in the Laizhou Mingbo cage base, the cage relay breeding after two months, the average individual weight of 350 g, the average one-tailed monthly weight gain 62.5 g, the survival rate of 92.02% ; selecting average individual weight of 152 g large-sized the Epinephelus moara in Lianyungang Zhongli cage base. Relay breeding after four months, the individual average weight increased to 425 g, the average one-tailed monthly weight gain 68.25 g, the survival rate of 96.00%, the grouper cage culture compared with industrialized recirculating aquaculture, an average monthly rate of weight gain increased by 54.6% to 68.9%.
