鱼粪洄游速度的研究,无论理论上还是在实践方面都具有趣味,特别是对洄游鲑游泳的生物能量季相的揭露具有很大的意义。对于鱼类游泳效率提高的特性总的综合有:特殊的体型,粘液的覆盖,肌肉的合理分布,组织和气体代谢能量的可能。可见,最好的游泳速度是在能量消耗最低的情况下。这在游泳鱼类远距离的和疲劳的洄游时期内具有特殊的意义。实验证明:无疲劳的鲑科鱼类每秒钟可长时期的维持3—4体长(L)的游泳速度。用
The research on the speed of fish dung migration is of great interest both in theory and in practice. Especially, it is of great significance to disclose the seasonal phase of bioenergy of migratory salmon swimming. The general synthesis of characteristics that improve the efficiency of swimming in fish are: special body size, mucus coverage, rational distribution of muscle, tissue and gas metabolism potential. Visible, the best swimming speed is in the case of the lowest energy consumption. This is of special significance during long-range and tired migration of swimming fish. Experiments show that: fatigue-free salmonids per second long-term maintenance of 3-4 body length (L) swimming speed. use
