摘要: AbstractThis study investigated the effect of exhaustive exercise on swimming performance Siberian Sturgeon Acipenser baeri and time required for recovery. Critical speed (Ucrit), maximum metabolic rate (MMR), coefficient (c), excess postexercise oxygen consumption (EPOC) were measured three groups juvenile sturgeon by stepped velocity tests at 20°C in a fish respirometer. After recovery period 1 h (group 1), 1 d 2), or week 3), four parameters determined second results compared. The Ucrit was 3.26 ± 0.11 body lengths per (mean SE). period, 78% its initial value complete slightly more than d. Recovery MMR followed same pattern. exponent (c) approximately 1.0, indicating that is an efficient swimmer; efficiency decreased after appeared to last least ...
