摘要
为了解低频振动刺激对大黄鱼行为及生理的影响,通过自制钢制水槽及作动器模拟养殖舱振动125 Hz(150 dB)、200 Hz(150 dB)分别对250 g组和500 g组大黄鱼进行连续1 h振动刺激试验,以此确定大黄鱼行为反应及生理生化指标变化(皮质醇、肾上腺素、甲状腺素)。结果显示:在振动刺激过程中,试验鱼未出现明显惊扰反应现象;250 g试验组,125 Hz频率条件下肾上腺素变化(增长约40.93%)最为显著(P<0.05),200 Hz频率条件下甲状腺素(增长约41.08%)变化最为显著(P<0.05);500 g试验组,125 Hz频率条件下甲状腺素(增长约28.68%)变化最为显著(P<0.05),200 Hz频率条件下也是甲状腺素(增长约41.79%)变化最为显著(P<0.05)且高于125 Hz频率组,故认为两组试验鱼均对200 Hz振动刺激更为敏感。本研究为提升大黄鱼的生长率、存活率以及深远海养殖新空间的新型海上养殖平台建设与发展提供参考。
In order to understand the effect of low-frequency vibration stimulation on the behavior and physiology of Larimichthys crocea,this study simulated the vibration of breeding cabin by self-made steel sink and actuator,and used the main frequency of underwater noise of traditional knocking operation to catch large yellow croaker.The frequency of 125 Hz(150 dB)and 200 Hz(150 dB)were used to conduct vibration stimulation experiments on 250 g and 500 g groups of large yellow croaker to determine the behavioral response and physiological and biochemical changes of large yellow croaker(cortisol,epinephrine,thyroxine).The results showed that:(1)In the early stage of acoustic stimulation,the behavioral responses of the two groups of test fish were characterized by random movement,cruising away after slow approach,free or around cruising.After adaptation,the test fish were basically in a regular or free cruising around the wall,cruising away after slow approach,or stagnant,and there was no obvious disturbance response.(2)In 250 g test group,the change of adrenaline at 125 Hz frequency(about 40.93%increase)was the most significant(P<0.05).Under the condition of 200 Hz frequency,the change of thyroxine(increased by about 41.08%)was the most significant(P<0.05).Except for increase of other blood indexes except epinephrine was higher than that of 125 Hz frequency group.Therefore,250 g large yellow croaker was more sensitive to 200 Hz.In the 500 g test group,the change of thyroxine(increased by about 28.68%)at 125 Hz frequency was the most significant(P<0.05),and other blood indexes decreased.Under the condition of 200 Hz frequency,the change of thyroxine(increased by about 41.79%)was the most significant(P<0.05)and higher than that of 125 Hz frequency group,while other blood indexes increased in different degrees in 200 Hz frequency group.Therefore,the 250 g and 500 g groups were more sensitive to 200 Hz vibration stimulation.In this study,the effects of low-frequency vibration stimulation on the behavioral response and physio
