Abstract

At four temperatures (T = 15, 20, 25 and 28° C) swimming performance of Dicentrarchus labrax was significantly correlated with total length (23-43 mm L T); r 2 = 0.623-0.829). The relative critical swimming speed (RU crit = U critL T -1), where U crit is the critical swimming speed, was constant throughout the L T range studied. The significant effect of temperature on the relative critical swimming speed was described binomially: RU crit = - 0.0323T 2 + 1.578T - 10.588 (r 2 = 1). The estimated maximum RU crit (8.69 L T s -1) was achieved at 24.4° C, and the 90% performance level was estimated between 19.3 and 29.6° C. © 2002 The Fisheries Society of the British Isles.
