Abstract: Fish swimming performance is a key to understanding behavioral strategies that affect fish migration, habitat selection, reproduction, predator-prey interaction, etc. Quantification of fish swimming performance through either step-increase (Ucrit) or fixed velocity testing is influenced by channel geometry size and length. Since time to fatigue, the swimming time after which a fish is no longer able to swim against a given flow condition is the prime yardstick to evaluate swimming performance, lacking a common time to fatigue definition could potentially lead to a specious assessment of the fish swimming performance.
