船舶噪声对大西洋鲑体质量、皮质醇及部分免疫指标的影响

Effect of ship noise on weight,cortisol and some immune indices of Salmo salar

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。

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.
