微量元素在鱼体内主要是作为酶的辅基成分或酶的激活剂参与机体的调节代谢,其缺乏或过多,可导致鱼体出现异常,并造成生理障碍,通常需在饲料中注意予以补充。 1 铁铁在鱼体中分布广泛,约60％-70％存在于血红蛋白中,是体内运输氧气和二氧化碳的最主要载体。在细胞氧化中铁是细胞色素氧化酶和黄素蛋白等的组成成分, 在氧化还原反应中起到传递氧的作用。饲料中缺铁时,
Trace elements in the fish mainly as a cofactor of enzyme or enzyme activator involved in the body’s regulation and metabolism, the lack of or excessive, can lead to fish abnormalities, and cause physical disorders, usually need to be noted in the feed to be supplemented . 1 Iron is widely distributed in fish and about 60-70% is present in hemoglobin, the most important carrier for the transport of oxygen and carbon dioxide in the body. Iron oxide in the cell is a cytochrome oxidase and flavoprotein and other components, in the redox reaction plays a role in the transfer of oxygen. Iron deficiency in feed,
