摘要
采用续航游泳时间评测指标作为评测鱼类游泳能力的方法,对一龄美国红鱼、鲈鱼、斜带髭鲷的续航时间,美国红鱼的临界(游泳)速度以及水温对美国红鱼续航时间影响进行了初步研究。结果表明,三种鱼中,美国红鱼耐流能力最强,其次为鲈鱼和斜带髭鲷。美国红鱼、鲈鱼、斜带髭鲷三种鱼的续航时间(或续航能力)与水流流速呈乘幂递减关系。水温对美国红鱼的游泳能力有显著的影响,试验结果表明,本文研究的美国红鱼,在水温20℃、流速84cm/s下的持续续航时间最长,可认为是该规格美国红鱼最适游泳水温范围。
In this paper, the method of sustained swimming time was adopted, experimental tests on the swimming performance of three one-year old cage farmed fishes, Sciaenops ocellatus, Lateolabrax maculatus, and Hapalogenys nitens, were carried out. S. ocellatus was the best swimmer, followed by L. maculates and then H. nitens. Based on regression analysis, power function relationships were found between sustained swimming time and flow velocities for these fishes. Temperature had remarkable effect on S. ocellatus’s swimming performance, and its favorite swimming temperature was found around 20℃.
