| 中文摘要: |
| 黄姑鱼(Nibea albiflora)是极具海水养殖潜力的高价值经济鱼类。研究不同水温(14～32℃)和盐度(5～45)条件下黄姑鱼受精卵的孵化,结果表明,水温低于17℃和高于32℃时不能孵化;盐度低于15和高于50时也不能孵化。在海水盐度25时,孵化适宜水温为20～29℃,最佳水温为20～23℃;在水温(22.0±0.5)℃时,黄姑鱼孵化的适宜盐度为25～40,最佳盐度为25。通过均匀设计,分析水温(X1)和盐度(X2)对孵化率(Y)的综合影响,获得最佳回归模型为Y=254-4.52X1-2.78X2(R2=0.8808),水温和盐度对回归的贡献率分别为64.8%和55.1%;预测最佳孵化条件为水温20℃、盐度24。 |

| Spotted maigre Nibea albiflora is a fish species that has aquaculture potential in China because of its high market value. The incubation of fertilized eggs was studied at the temperature in the range of 14一32℃and salinity ranging from 5 to 45. Fertilized eggs did not hatch，when the water temperature was below 17℃ or above 32℃.water salinity was below 15 and above 50. With water salinity at 25，the suitable temperature for hatching ranged from 20 ℃ to 29℃，and the optimum temperature was from 20℃ to 23℃.With water temperature at(22. ±0. 5)℃，the suitable salinity for hatching was in the range of 25一40，and the optimum salinity was 25 .The optimal regression model was obtained through an analysis of temperature ( X1)，salinity ( X2)and hatching rate(Y) by homogeneous design，which had the following expression: Y=254一4. 52X1一2. 78X2(R2=0.8808).The regression contribution rates of temperature and salinity were 64.8%，55.1%separately. Model calculation predicted that the optimal hatching temperature was 20℃ and salinity of 24. |
