Nordic Seals: Seal populations in the North-Atlantic, Arctic Ocean and adjacent waters
Notice bibliographique
Résumé
This report is a part of the Nordic networking project Nordic Seals, which is supported by the Nordic Council of Ministers Working Group for Fisheries (AG Fisk). The project’s objectives are to gather, analyse and disseminate information on the populations of seals in the North-Atlantic, Arctic, and adjacent waters, and their environmental, social, and economic impacts. As several seal populations have grown in the North Atlantic, Arctic, and adjacent waters, they have become a controversial topic with fishermen and other stakeholders within seafood value chains who claim that they negatively affect commercial fish stocks, catch, product quality and economic viability of the fisheries. Many scientists and conservationists have on the other hand pointed out the lack of understanding of the functioning of seals in the ecosystem. Although seals are known to feed on commercial fish species, research on their effect on fish size and age distribution of prey populations, as well as stock size, is incomplete. More knowledge on the role and effects of seals in the ecosystem is needed. As some seal populations still suffer from hunting that took place in the past, decisions on seal management must be well founded. Bycatch of seals is today the main threat to seal populations in many areas, which must be taken seriously. Depredations and damage to fishing gear and fish farms caused by some species of seals is well documented. The exact ecological and economic impact of these is however largely unknown. There are ongoing initiatives that aim to fill in these knowledge gaps, but results are largely lacking. The issue of nematode roundworms that are parasites causing quality defects in commercial fisheries, which seals play a major role in distributing as hosts, has been a major concern for fishermen. Controlling seal populations was in the past believed to be important to limit nematode distribution and therefore considered vital to safeguard the economic viability of the seafood industries in the North Atlantic. Seals have a long history as an important food source. Seal meat is nutritious and full of important amino acids, vitamins, and minerals. But they also contain food safety threats, such as nematode ringworm parasites, and bioaccumulated trace elements. The import bans on seal products imposed by the US and EU have made any kind of trade in seal products difficult. But as some seal populations grow in certain areas, the question on potential utilisation becomes more pressing. To answer that question there is a need for more research to better understand the role of seals in the ecosystem, and on how to produce sustainable, safe and stable food or feed ingredients from seals.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
