试验按两因子三水平有重复试验设计，网箱养团头鲂。经９０天饲养结果表明：配合饲料中锰（Ｍｎ２＋）和钴（Ｃｏ２＋）的添加量分别为１２９ｐｐｍ和２３４ｐｐｍ时，团头鲂鱼种的生长效果相对最佳；饲料中添加适量的Ｃｏ２＋对团头鲂的生长有促进作用，且在０—２３４ｐｐｍ范围内有递增趋势；当Ｍｎ２＋的添加量为２５８ｐｐｍ时，其生长相对减慢 The test is based on two factors and three levels of repeated experimental design, cage rearing head 鲂. The results of feeding for 90 days showed that the growth of bream fish was the best when the contents of manganese (Mn2 +) and cobalt (Co2 +) were 129ppm and 234ppm, respectively. The suitable feed Co2 + promoted the growth of bream, and it showed an increasing trend in the range of 0-234ppm. When Mn2 + was added at 258ppm, its growth was relatively slow
