How the spatio-temporal overlap of cod, haddock, and capelin larvae affects their recruitment in the Norwegian–Barents Sea system
The Norwegian-Barents Sea (NBS) system is very productive; however, the extent to which this productivity varies remains uncertain for many species. Cod Gadus morhua , haddock Melanogrammus aeglefinus , and capelin Mallotus villosus are 3 key species that overlap in a large portion of the NBS ecosys...
