| 摘要: |
| 矿物质是鱼类必需的营养素之一。海水中含有大量的无机盐,海水鱼类虽可通过饮用海水直接摄取,但是这些矿物质并不能满足鱼类的全部需求,在饲料中还必需予以添加,因此研究海水鱼类对矿物质的需求具有重要的意义。
黑鲷(Sparus macrocephalus)是我国北方最有价值的海水养殖鱼类之一,目前黑鲷养殖业已经逐步发展起来,开展黑鲷营养需求和人工配合饲料的研究已成为当务之急。本文报道了黑鯛对Ca,P,K,Mg和Mn的需求研究结果。 |

| Abstract: |
| The requirements of black sea bream, Sparus macrocephalus, for calcium, phosphorous, potassium, magnesium and manganese were studied using semi-purified diets and orthogonal design. Based on the fish weight gains, survival rates and the contents of the minerals in the fish liver, the proper contents of phosphorous and manganese in the fish diets are 0.99% and 60 mg/kg, respectively. Supplementation of calcium, potassium and magnesium in the diets is not necessary. |
