Linking spawning ground extent to environmental factors - patterns and dispersal during the egg phase of four North Sea fishes
International audience Previous studies have shown that four commercially important demersal species, namely Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus), whiting (Merlangius merlangus), and European plaice (Pleuronectes platessa), spawn in distinct areas across the North Sea.
