This contribution presents unreported catches for selected fisheries and species from Norwegian waters, with particular emphasis on cod (Gadus morhua) in the Barents Sea between 1950 and late 1990s. Estimated discard rates ranged from over 20% in the 50s to approximately 10% of reported landings in the 90s. Additional species covered include redfish (Sebastes spp.), blue whiting (Micromesistius poutassou), haddock (Melanogrammus aeglefinus), whiting (Merlangius merlangus) and saithe (Pollachius virens). Some information on shrimp (Pandalus borealis) and marine mammals is also presented.
