钙钙参与骨和齿的形成、血液凝固、神经传导等。缺乏钙会使发育停滞,导致佝偻病、骨多孔症、痉挛。对钙需求量高的(鱼师)鱼和鳗鲡,缺乏钙会引起生长停滞,骨骼变形。△磷磷参骨和齿的形成、酸和碱的平衡。缺乏磷,则会体质虚弱、骨的矿物质不足,产生钙消耗。缺磷,(鱼师)鱼会发生动作迟缓、体色黑化、痉挛、骨变形等现象。鲤鱼、虹鳟、白鲑、银鲑、真鲷、罗非鱼饲料中可利用磷的必需量分别为0.5％—0.7％、0.7％
Calcium and calcium involved in the formation of bone and teeth, blood coagulation, nerve conduction and so on. Lack of calcium can retard development, leading to rickets, osteoporosis, spasticity. The high demand for calcium (fish division) fish and eels, the lack of calcium will cause growth retardation, bone deformation. △ phosphorus phosphorus bone and tooth formation, acid and alkali balance. Lack of phosphorus, it will be frail, bone mineral deficiencies, resulting in calcium consumption. Phosphorus deficiency, (fish division) fish will occur slow movement, body color blackening, cramps, bone deformation and other phenomena. Carp, rainbow trout, whitefish, silverfish, red sea bream, tilapia feed available phosphorus were 0.5% -0.7%, 0.7%
