title: Effects of age and size on critical swimming speed of juvenile Chinese sturgeon Acipenser sinensis at seasonal temperatures.
abstract: Changes in the critical swimming speed (Ucrit , cm s(-1) ) with ontogeny of 2·5-12·5 month-old juvenile anadromous Chinese sturgeon Acipenser sinesis were measured in a modified Blazka-type swimming tunnel. The absolute Ucrit increased with length, mass and age; the relative U(')crit (body lengths, s(-1) ), however, decreased. Juvenile A. sinesis did not display a parr-smolt transformation at the length or age threshold to tolerate full-strength seawater.
