Fisheries Research, 2006 Escapement of Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus) and saithe (Pollachius virens) beneath a commercial bottom trawl, rigged with a 60 cm diameter rockhopper gear, was studied in the Barents Sea. The study was performed off the coast of north Norway in March/April 2003.

Spatial habitat partitioning enables coexistence of three Gobiidae species in estuarine environments
Journal of Fish Biology, EarlyView.Abstract This study examines resource partitioning (feeding morphology, diet and habitat partitioning) among three gobiid species, the Knysna sandgoby Psammogobius knysnaensis, the prison goby Caffrogobius gilchristi and the river goby Glossogobius callidus, within an estuarine environment.

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution
Journal of Fish Biology, EarlyView.Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.
