Potential sources of unaccounted mortality in the fishery for Norwegian spring spawning herring
The stock of Norwegian spring spawning herring (NSSH) is managed and fished by 5 different parties. These are the EU, Faroe Islands, Iceland, Norway and Russia. The most common gears are purse seine and pelagic trawl. The fishery is regulated by quota, and to prevent the fishery exceeding the quota,...

Taking account of how the fishery is conducted, potential sources of unaccounted mortality may be identified.
