| 摘 要： | １９９２￣１９９３年，用不同Ｃａ＾２＋，Ｍｇ＾２＋和Ｋ＋含量的人工配制海水，孵化黑鲷（Ｓｐａｒｕｓ ｍａｃｒｏｅｐｈａｌｕｓ Ｂａｓｉｌｅｗｓｋｙ）受精卵，培育前期仔鱼。实验揭示了：在没有Ｃａ＾２＋的海水中不能孵出仔鱼，在没有Ｍｇ＾２＋的海水中能孵出少量畸形仔鱼；低Ｋ＾＋对黑鲷受精卵孵化无明显影响，但对早期仔鱼的影响明显。针对咸淡水域海水鱼类育苗的特点，提出了调配海水中适宜的Ｍｇ＾２＋／Ｃａ＾２＋

| Abstract: | In 1992 and 1993, artificial sea water with different concentrations of Calcium, Magnesium and Potassium were prepared for the hatching of the fertilized eggs and the incubation of yolk sca fry of Sparus macrocephalus. The results of experiment were as follows: none of yolk sca fry was hatched in the calciumfree sea water and a small amount of abnormal yolk sca fry were hatched in magnesium-free sea water, and there was no significant effect of low potassium on the hatching of the fertilized eggs but quite significant on the survival of yolk sea fry. In view of nursing of seawater fish in brackish water, we suggested that the amount of Ca2+ and Mg2+ should be controlled in the range of 290-330 mg/L and 870- 1 000mg/L, respectively, and the ratio value of Mg: Ca should be controlled between 2. 90-3. 30. The results had been qualified in the productive nursing in 1992 and 1993. |
