The physiological responses of fish to underwater noise are poorly understood and further information is needed to evaluate any possible negative effects of sound exposure. We exposed European sea bass and gilthead sea bream to a 0.1-1 kHz linear sweep (150 dB(rms) re 1 microPa). This band frequency is perceptible by many species of fish and is mainly produced by vessel traffic. We assessed the noise-induced motility reaction (analysing the movements) and the haematological responses (measuring blood glucose and lactate, and haematocrit levels). The noise exposure produced a significant increase in motility as well as an increase in lactate and haematocrit levels in sea bream and sea bass. A significant decrease of glucose was only observed in sea bream. A linear correlation between blood parameters and motility in fish exposed to the noise was observed. The acoustic stimulus produced intense muscle activity.
鱼类对水下噪声的生理反应知之甚少,需要进一步的信息来评估声音暴露可能产生的任何负面影响。我们将欧洲海鲈和金头鲷暴露在 0.1-1 kHz 线性扫频(150 dB(rms) re 1 microPa)中。该频段频率可被许多鱼类感知,主要由船舶交通产生。我们评估了噪声引起的运动反应(分析运动)和血液学反应(测量血糖和乳酸以及血细胞比容水平)。噪声暴露不仅导致海鲈和海鲈鱼的运动显著增加,还导致乳酸和血细胞比容水平升高。仅在金头鲷中观察到葡萄糖显著下降。在暴露于噪声的鱼类中,血液参数与运动之间存在线性相关性。声刺激产生了强烈的肌肉活动。
