NSC, North Sea cod; NEAC, north-eastern Arctic cod.

Values are means ± s.e.m. (N=5-6).

Hepatosomatic indices (HSI)=(liver:body mass)×100.

Condition factors were calculated as previously described(Lucassen et al., 2003). Condition factor=[mass (g)×total length(cm)-3]×1000.

Liver lipid content is relative to fresh mass.

RNA content in liver was determined using the RNeasy kit from Qiagen (Q)and in muscle, the Trifast kit (T).

*

Significant difference from the warm-acclimated control group within a population.
