网箱养鱼能合理解决溶氧,密度、饵料等之间关系,因此可获高产,为世界各国所重视,我国利用网箱依靠天然饵料,培育鱼种,已取得良好效果。 1978年上海市水产研究所利用网箱进行了养殖非洲鲫鱼高产试验。试验从5月23日起至9月20日结束,经119天饲养。最高产量达到97.0公斤/米~2,放养时规格为1.47克/尾,起捕时长到59.8克/尾。四只试验网箱的饵料系数分别为1.76、1.88和2.16。
Cage fish can reasonably solve the relationship between dissolved oxygen, density, food and so on, so high yields can be obtained for all countries in the world, China’s use of cages rely on natural food, cultivate fish species, has achieved good results. In 1978, Shanghai Fisheries Research Institute made use of cages to conduct high-yielding tests on African crucian carp. The trial ended from May 23 to September 20 and was maintained for 119 days. Maximum production reached 97.0 kg / m ~ 2, stocking specifications for 1.47 g / tail, catch up to 59.8 g / tail. The feed rates for the four experimental cages were 1.76, 1.88 and 2.16, respectively.
