<jats:p>Exercise conditioning at 1.2–2.4 body lengths∙s<jats:sup>−1</jats:sup>for 60 d significantly improved final weights, specific growth rates (SGR), 2-min critical swimming velocities, red muscle cross-sectional areas at 80% standard length (SL), and red:white muscle ratio at 80% SL in both cultured and wild young-of-the-year striped bass (Morone saxatilis). Moreover, wild fish had final weights and SGR greater than cultured fish in both exercised and unexercised groups. Exercise conditioning also increased white muscle cross-sectional areas at all sections (50, 65, and 80% SL) in the cultured but not in the wild fish, although white muscle areas of exercised wild fish were significantly greater than in the unexercised cultured fish. It is suggested that exercise-conditioned striped bass used for stocking purposes might show increased survival rates in the wild.</jats:p>
