摘要
P>The prime objective of this study was to evaluate differences between the swimming performance of two distinct life stages of European eels. The critical swimming speed (U(crit)) of 29 yellow- and 33 silver-phase eels was evaluated in a swim tunnel. Silver-phase eels showed a better swimming performance (U(crit) = 0.66 ms-1) than yellow individuals (U(crit) = 0.43 ms-1). Male and female silver eels reached an identical U(crit) despite their different sizes, which may be a strategy to increase the synchronization of arrival at the spawning grounds.
