Atlantic cod has been proved to be adapted genotypic and behavioural to different environmental temperatures. We compared the oxygen consumption rate (VO2/M) of juvenile Atlantic cod from both different family crosses and with different Pan-I genotypes acclimated to 4ºC, 8ºC and 12ºC and when exposed to an acute thermal challenge. No differences were found between genotype at any acclimation temperature or between families at 8ºC (Tac) however differences were found among families at 4ºC and 12ºC (Tac) although they do not seem to be associated with maternal size or studied conditions. The results suggest that Pan-I locus is not a perfect marker for migratory behaviour and that genetically inherit abilities from parental can produce differences between their spawning though further studies need to be done to assess this inherit conditions.
