摘要： 为优化大黄鱼活体运输的条件，对大黄鱼的生态冰温进行探索。分析鱼水质量比和暂养时间2个因素对大黄鱼保活时间的影响，在此基础上设计3因素3水平的正交试验，以期找到大黄鱼保活的适合条件。研究结果显示：大黄鱼的生态冰温为-2°C ~7°C；鱼水质量比及暂养时间对大黄鱼保活时间均有显著影响（P<0.05）；在温度为5°C～7°C、鱼水质量比为1:4、暂养时间为48 h的条件下进行保活，保活时间可超过19 h。本研究结果可为大黄鱼活体运输提供参考。
Abstract: In order to optimize the live transport conditions of Larimichthys crocea, its ecological ice-temperature was explored, the effects of fish/water mass ratio and holding time on its keep-alive time was analyzed, and an orthogonal experiment of 3 factors and 3 levels was designed to find suitable conditions for keeping Larimichthys crocea alive. The results showed that the ecological ice-temperature of Larimichthys crocea was -2°C ~7°C; fish/water mass ratio and holding time had significant effects on the keep-alive time of Larimichthys crocea (P<0.05); the keep-alive time could be over 19h when the temperature was 5~7°C, the fish/water mass ratio was 1:4 and the holding time was 48h. The results could provide references for live transport of Larimichthys crocea.
