中文摘要:以珍珠龙胆石斑鱼为原料,采用单因素实验研究暂养时间、保活温度、保活密度、盐度等条件对石斑鱼存活时间的影响,并进行了正交实验优化,对保活过程中水质指标与血清生化指标进行了分析,探讨珍珠龙胆石斑鱼有水保活的最适条件。结果表明:珍珠龙胆石斑鱼经停饵暂养48 h后,经平均1~2℃/h的梯度降温模式降至休眠温度,在温度15℃,保活密度100 g/L、盐度25‰条件下的存活时间可达(168±8) h。在该条件下保活72 h后水中总氨氮浓度为(7.28±0.06) mg/L,血糖、血清谷丙转氨酶活性与球蛋白含量显著增加(p <0.05),而皮质醇、甘油三酯、尿素氮含量和天冬氨酸氨基转移酶、乳酸脱氢酶酶活性均无显著性变化。结果表明该条件适合珍珠龙胆石斑鱼的长途保活运输。
外文摘要:The effects of holding time,temperature,density,salinity and cooling model on the survival time of grouper( ♀Epinephelus fuscoguttatus × ♂ Epinephelus lanceolatus) were studied by single factor experiment and the orthogonal experiment.The water quality index and serum biochemical index were analyzed in order to explore the optimum conditions for the conservation of grouper( ♀ E. fuscoguttatus × ♂ E.lanceolatus) with water. Results showed that the survival time of the grouper was( 168 ± 8) h after holding for 48 hours,then inducing to dormant by a gradient cooling model at the average reducing ratio of 1~2 ℃/h and keeping alive under the condition of 15 ℃,25‰ salinity and 100 g/L of fish density.The total ammonia nitrogen content in water after keeping alive for 72 h was( 7.28 ± 0.06) mg/L. Blood glucose,globulin concentration and serum alanine aminotransferase activity were increased significantly( p〈0.05),while cortisol,triglyceride,urea nitrogen concentration and aspartate aminotransferase and lactate dehydrogenase activities were not changed significantly. The results showed that this survival condition is suitable for the long distance transportation of grouper( ♀ E. fuscoguttatus ×♂E.lanceolatus).
