| 摘 要： | 在室内自然降温条件下，研究了马来西亚红罗非鱼（Oreochromis mossambicus×0．niloticus）致死低温，检测了在温室越冬温度（17．8℃）和低温胁迫下开始死亡时红罗非鱼血清的生化指标。结果表明，当水温降到8．6℃时，马来西亚红罗非鱼开始死亡，死亡低温范围为8．6—6．4℃，半致死低温为7．6℃；8．6℃时，红罗非鱼血清中谷丙转氨酶（ALT）、谷草转氨酶（AST）、乳酸脱氢酶（LDH）、碱性磷酸酶（ALP）FAJ）]~L酸激酶同工酶（CK—MB）5种酶的活性显著高于17．8℃时Op〈0．05），肌酐（CREA）含量、I（＋浓度显著上升Ok0．05），总蛋白（TP）、白蛋白（ALB）、球蛋白（GLO），及Ca2‘含量小幅增加，而Na＋和cr含量均显著下降（P〈0．05），胆固醇（CHOL）和甘油211（TG）含量略有降低。

| Abstract: | The lethal temperature was studied in Malaysian red tilapia （Oreochromis mossambicus xO. niloticus） under indoor natural cooling, and serum biochemical indexes were tested at water temperature of 17.8~C and beginning of death in the red tilapia. The re- suits showed that red tilapia death appeared when the temperature dropped to 8.6~C, with range from 8.6~C to 6.4~C, and the LCs0 low temperature of 7.6~C. There were significantly higher activities of ALT, AST, LDH, ALP and CK-MB at 8.6~C compared with at 17.8~C （P〈0.05）. The CREA level and the content ofK＋ were found to be significantly increased （P〈0.05） at 8.6~C, while TP, ALB, GLO and the content of Ca2＋ increased slightly. However, the contents of Na＋ and C1- were significantly decreased （P〈0.05）, with slightly lower CHOL and TG levels. |
