dc.description.abstract | This paper is based on experiments to test if differences in migratory behaviour of Norwegian
coastal cod and north east Arctic cod is related to parental origin or, alternatively, is related to
the environmental experienced during the premature stages. Earlier experiments have shown
that when wild fish from the two groups are transplanted and released at a new location, their
behaviour after release differ distinctly. The two groups of cod in the present study were raised
in captivity under identical conditions. Mature fish were tagged with acoustic transmitters and
their behaviour studied during a week's period after release. Methods and design were the
same as in the earlier experiments, and the results signified no behavioural differences between
the two groups of fish. This might be an indication of strong environmental influence on migratory
behaviour in cod. The number of released fish were low and the results have to be verified
by new trials. | no_NO |
