摘　　要：为了优化增殖放流技术,减少运输胁迫,选取体长(118.9±8.1) mm、体质量(39.6±8.4)g的条石鲷(Oplegnathus fasciatus)幼鱼作为研究对象,在振荡频率0、60、100、140、180 r/min下模拟运输24 h,研究振荡频率对条石鲷幼鱼生理应激以及对水体总氨氮含量的影响。试验结果显示,随着振荡频率的提高,条石鲷幼鱼血液中的皮质醇、血糖、乳酸水平升高(P<0.05),肌糖原水平则降低(P<0.05);运输水体的总氨氮含量也随着振荡频率的提高而快速升高。结果表明,较高的振荡频率会加剧条石鲷幼鱼的生理应激,提高其能量消耗,并导致运输水质快速恶化。To optimize hatchery-release techniques and reduce transportation stress,the effects of transportation oscillation frequency on physiological stress and total ammonia content in water of juvenile rock bream Oplegnathus fasciatus were studied in laboratory conditions.The fish with a mean body length of(118.9±8.1)mm and average body weight of(39.6±8.4)g were simulated transport at varied oscillation frequencies of 0,60,100,140 and 180 r/min for 24 h.The results showed that the levels of cortisol,lactic acid and serum glycogen increased with the increase of oscillation frequency(P<0.05),while muscle glycogen level decreased(P<0.05),and the total ammonia nitrogen content increased rapidly at higher oscillation frequencies.This study indicates that physiological stress of juvenile rock bream can be aggravated at relatively high oscillation frequencies,leading to energy consumption increase and the rapid deterioration of transport water quality.
