In 1983 and 1984 about 14 000 seven month old pond or basin
reared coastal cod were tagged and released in Heimarkspollen
and Osen in Western Norway. In May 1984 fishing in the release
areas was initiated and local fishermen were asked to report
recaptures. Growth of released cod was at least as good as growth of wild
cod in the area. The 1983 release contributed about 30% of this
yearclass in Osen and about 50% in Heimarkspollen. The 1984
release contributed about 80% of this yearclass in
Heimarkspollen. There seems to be no difference in food
preference between released and wild cod. The reared cod are
very stationary.
