dc.description.abstract | In June 1995 and 1996 demersal fishes on the continental slope of the eastem
Norwegian Sea were sampled to study distribution patterns and community structure.
The diets of the more abundant slope species were characterised and linkages within
the upper slope food-web identified.
Few cases of predator-prey relationships between the typical slope fishes were found.
Most of the smaller fishes fed on epibenthic crustaceans such as amphipods and
mysids, while pelagic crustaceans and fish dominated the diets of larger fishes.
Herring ( Clupea harengus) and blue whiting (Micromesistius poutassou) were
important prey items of Greenland halibut (Reinhardtius hippoglossoides), and were
also eaten by Lycodesfrigidus, Raja hyperborea and roughhead grenadier (Macrourus berglax). At !east for the latter three species this probably reflected scavenging. | no_NO |
