Sammendrag
Juvenile coastal cod (Gadus morhua L.), hatched in the
laboratory and reared in a large outdoor basin at Flødevigen
Biological Station, were tagged and released in coastal waters
in southern Norway. They were released at an age of 6 months
and a length of about 10 cm. Tag return to 1 January 1980 was
about 4% of the 712 cod released in 1976 and 10% of the 371
released in 1976 and 10% of the 371 released in 1977. About
90% of the cod were caught by anglers, in the area of release.
The tagged cod showed t h e same growth rate as wild cod in the
same area. The relatively high percentage recapture of cod
released in 1977 might indicate a potential high survival rate
of released cod reared in large basins.
