The Skagerrak is a small area where vessels often cross between EU and Norwegian waters, so there was a need to harmonise technical and other measures, including a discard ban, which is law in Norway.
Skagerrak on väike ala, milles laevad ületavad sageli ELi ja Norra vete piiri, mistõttu oli vaja ühtlustada tehnilisi ja muid meetmeid, sealhulgas tagasiheite keeldu, mis on Norras seadus.
