Sammendrag
Coastal cod, (Gadus morhua L.), hatched in the laboratory and
reared in a large outdoor basin at Statens Biologiske Stasjon
Flødevigen, have been tagged and released in coastal waters in
southern Norway, in 1976 and 1977 respectively 712 and 371 at
an age of 6 months and a length of about 10 cm. Till 1 January
1980 tag return has been about 4 and 10 percent for cod released
in 1976 and 1977 respectively. About 90 percent of the cod were
caught in the area of release by game fishing. The tagged cod
showed the same growth rate as wild cod in the same area. The
relative high percent recaptures of cod released in 1977 might
indicate a potential high survival rate of cod reared in large
basins.
