Diet and feeding strategy of Northeast Atlantic mackerel (Scombrus scomber) in Icelandic waters
Publisher's version Predator-prey relations, as well as the trophic ecology of highly migratory marine species, is important to understand their impact on the ecosystem. Conventional methods were used to study the diet composition and feeding strategy of the Northeast Atlantic mackerel (Scombru...
