Effects of prolonged and burst swimming on subsequent burst swimming performance of Gymnocypris potanini firmispinatus (Actinopterygii, Cyprinidae)

摘要: Fish swimming behavior is important for their survival. Burst swimming, prolonged and effect on each other were examined Gymnocypris potanini firmispinatus. Test fish randomly assigned to two groups, one group was tested critical speed (Ucrit), the burst (Uburst). After a 30-min recovery period, both groups subjected Uburst testing. The value measured following Ucrit test termed Uburst-c Uburst-b initial test. Results include primary findings. (1) There significant differences between Uburst-c, Uburst-b, indicating that of fatigue from subsequent performance significant. (2) ratio after resulting significantly lower than swimming. not Therefore, whether or leads deeper will require additional research. findings this study effects support continued improvement fishway design.
