Abstract: In order to investigate the effect of ship noise on weight, cortisol and some immune indices of Salmo salar, Salmo salar with an average weight of (44.01±11.0)g was selected. The changes in weight and ORT, AKP) and total bilirubin levels of Salmo salar were measured by testing the noise processing group [(120±5)dB, (150±5)dB)] and the control group. The results revealed no significant difference in the weight of Salmo salar between the test group and the control group (P>0.05), but significant difference in the total bilirubin,  alkaline phosphatase and cortisol from the beginning to the end of the test (P<0.05); on the10th day, the mass concentration of the test group was significantly higher than that of the control group, showing a trend of first rising, and then falling to stabilized. The difference between the groups was significant (P<0.05).The mass concentration of the biochemical indexes showed a trend of first going up, then down to stabilized. This study provides a reference for industrial healthly farming of Salmo salar .

摘要： 为探讨船舶噪声对大西洋鲑(Salmo salar)体质量、皮质醇及部分免疫指标的影响，选取平均体质量为（44.01±11.0）g的大西洋鲑，通过噪声处理组[(120±5)dB、(150±5)dB]以及对照组试验，测定大西洋鲑体质量以及机体血清中皮质醇激素（ORT）、碱性磷酸酶（AKP）及总胆红素含量的变化情况。结果显示：试验组和对照组的大西洋鲑体质量增长差异不显著（P>0.05），血清中总胆红素、碱性磷酸酶、皮质醇从试验开始至结束，差异显著（P<0.05），在第10天，试验组的质量浓度显著高于对照组，呈现先上升后下降并趋于稳定的趋势。两试验组存在差异显著（P<0.05），各生化指标质量浓度呈现先上升后下降并趋于稳定的趋势。该研究可为大西洋鲑工业化健康养殖提供参考。
