| 摘要: |
| 为突破广西地区珍珠龙胆石斑鱼工厂化健康育苗的技术瓶颈，提高广西地区珍珠龙胆石斑鱼人工育苗成活率和育苗质量，开展适合于广西地区的珍珠龙胆石斑鱼工厂化健康育苗技术的研究。本研究明确了珍珠龙胆石斑鱼工厂化育苗所需的适宜的光照强度、水体盐度、温度、溶氧和氨氮含量等水环境因子，探讨了生物饵料营养强化对育苗成活率的影响。试验表明，在光照强度为2 000~3 500 lux，水温28~31℃，盐度28‰~31‰，水体的溶氧量>6 mg/L的育苗条件下，石斑鱼鱼苗生长情况良好，育苗成活率达到10.5%，幼鱼平均全长25.5 mm。试验还表明，对生物饵料进行营养强化可以提高珍珠龙胆石斑鱼的育苗成活率。本研究成果有助于推动广西海水养殖业良种化进程、促进广西地区石斑鱼养殖业健康可持续发展。 |

| Abstract: |
| In order to break through the technical bottleneck of the healthy cultivation of hybrid grouper (Epinephelus fuscoguttatus♀×E.lanceolatus♂) in Guangxi,this study carried out scientific industrialized healthy breeding technology of hybrid grouper (Epinephelus fuscoguttatus♀×E.lanceolatus♂),which is suitable for Guangxi area,and could effectively improve the survival rate and quality of hybrid grouper larva.This study clarified the suitable water environmental factors such as optimum light intensity,water salinity,temperature,dissolved oxygen and ammonia nitrogen content in the industrialized breeding technology.The study also explored the effects of nutritional fortification of biological food on survival rate of hybrid grouper larva.The test showed that when the light intensity was controlled at 2 000~3 500 lux,the water temperature was kept at 28~31℃,the water salinity was kept at 28‰~31‰,and the dissolved oxygen content in the water was always above 6 mg/L,grouper larvae grew well and the survival rate reached 10.5% with the average body length of 25.5 mm.Moreover,the nutritional fortification of biological food had positive effects on the survival rate of hybrid grouper larva.The results of this study will help promote the process of high-quality marine aquaculture and promote the healthy and sustainable development of grouper breeding in Guangxi. |
