摘要
为研究海鲈(Lateolabrax japonicus)的游泳续航能力和游泳过程中的物质代谢规律,以深水网箱养殖的3月龄海鲈为研究对象,采用游泳续航时间和生化指标作为评测海鲈游泳能力和代谢规律的方法进行了试验。结果显示,海鲈的游泳续航时长为200 min,其续航能力强于大黄鱼而弱于美国红鱼。在游泳过程中,海鲈血糖浓度升高,但差异性不显著(P>0.05),肌糖原随着时间的增加显著减少(P<0.05),且肌糖原浓度在海鲈疲劳时接近于0。当鱼接近100%疲劳时,其肝糖原浓度也接近于0;当海鲈以不同疲劳程度游泳时,其肌肉乳酸脱氢酶浓度会显著升高(P<0.05)。表明海鲈的续航游泳过程伴随着无氧呼吸和有氧呼吸。
To study the swimming endurance and exercise metabolism of sea bass(Lateolabrax japonicus),the endurance time and biochemical indicators of 3-month-old sea bass were tested during swimming in deep water.The results showed that the swimming endurance time of sea bass was 200 min,which was longer than Larimichthys crocea and shorter than Sciaenops ocellatus.The blood glucose concentration of sea bass increased(P>0.05)while the muscle glycogen significantly decreased(P<0.05)during the swimming test.The concentration of liver glycogen decreased to about 0 and the concentration of muscle glycogen almost decreased to 0 when fatigue levels increased to 100%.On the contrary,the muscle lactate dehydrogenase concentration increased significantly with the rise of fatigue levels(P<0.05).These results indicated that the swimming process of sea bass was accompanied by anaerobic respiration and aerobic respiration.
