Swimming Performance of Four Carps on the Yangtze River for Fish Passage Design

Anthropogenic engineered structures alter the local ecological connectivity of river and survival habitat native fishes. The swimming performance is critical for establishing fish passage or habitat. This study evaluated four carps (black carp, grass silver carp bighead carp) with smaller body lengths (1.0–9.0 cm) in a flume. results showed that burst speed (m/s) increased length, relative (critical burst) (the divided by BL/s) decreases length. each species at two individual length groups (1.0–5.0 cm, 5.1–9.0 was significantly different (p < 0.05), water velocities should be less than speed. further provided data juvenile technical reference construction restoration
