Problems solved by technology

[0003] As people are more and more fond of turbot, the scale of breeding is also expanding. It is necessary to raise the broodstock of turbot separately to improve the reproductive ability of the broodstock. However, there are many kinds of turbot feed on the market , unbalanced nutrition, it is difficult to meet the reproductive needs of broodstock, therefore, the market urgently needs a special feed for broodstock
