Values given in parentheses are from the present study for S. lalandi, whereas all other values are for S. quinqueradiata[∼20°C data compiled from(Yamamoto et al., 1981; Yamamoto, 1991; Lee, K. S. et al., 2003b);25°C data compiled from (Ishimatsu et al., 1990; Ishimatsu et al.,1997; Lee, K. S. et al.,2003a)]; data for rainbow trout were compiled from(Holeton and Randall, 1967; Randall et al., 1967; Stevens and Randall, 1967; Kiceniuk and Jones, 1977; Brill and Bushnell, 1991; Farrell and Jones, 1992; Gallaugher et al., 1995; Altimiras and Larsen, 2000; Brill and Bushnell, 2001);data for tunas (skipjack and yellowtail) were compiled from(Bushnell et al., 1990; Brill and Bushnell, 1991; Jones et al., 1993; Bushnell and Jones, 1994; Dewar and Graham, 1994; Korsmeyer et al., 1997a; Korsmeyer et al., 1997b; Brill and Bushnell, 2001).
