Standard errors (±S.E.M.) are given for each coefficient.
The final multiple regression equations for all variables except V̇O_{2} and λ were the same for chub mackerel at both 18 and 24 °C.
↵ ^{*} Indicates a coefficient that does not differ significantly from zero (P>0.05).
FL, fork length (cm); l, stride length; λ propulsive wavelength; U, swimming speed; M, body mass.
