Swimming capability of target fish from eight hydropower stations in China relative to fishway design

The four major Chinese carp (MC), Schizothorax fish species (SF), and Cobitidae (CF) are the most important target in China. swimming behaviour study of three groups is key to fishway designs. 20 min critical speed (U crit-20 ) endurance relation body length, speed, water temperature were estimated using multiple linear regression. results indicated that both length had a significant effect on capability. Performance comparisons SF remarkably strong swimmer. CF possess slightly greater capability than MC. entrance velocity upstream should be U , but less maximum make flow out noticeable. distance could model at 1.2 m·s –1 . For downstream-migrating juvenile fish, it was suggested turbine intake sustained avoiding entering turbine.
