Size–dependent mortality of juvenile reared Atlantic cod released in a small fjord

This is the authors' abstract. We don't add key points for this paper.

Less than 2% of the O–group cod Gadus morhua of mean length 8 cm at release survived their first 3 months in the sea, while c . 75% of those of mean length 12 cm survived a similar period. There was no difference in mortality rates during their first winter at sea between groups with mean lengths 12 and 17 cm at release. The results could probably be explained by the relatively small sizes of predatory fishes in the fjord and the degree of overlap between size at release and the preferred prey sizes of the predators.
