. The behaviour was compared of juvenile reared and wild cod, Gadus morhua L., towards a potential predator. The cod were allowed to swim and feed freely in a tank, separated from a predator (large cod) by a transparent Plexiglas wall. The reared cod remained further from the predator than the wild cod, and were slower to approach the predator. The relevance of these findings for extensive rearing of cod is discussed.
