Hazard and catch composition of ghost fishing gear revealed by a citizen science clean-up initiative
Thorbjørnsen, Susanna Huneide; Synnes, Ann-Elin; Løset, Ingrid Disch; Kleiven, Alf Ring (Peer reviewed; Journal article, 2022)Ghost fishing, the continued catch of fishes and invertebrates by lost fishing gear, represents an animal welfare issue as well as a waste of both potential food and ecosystem resources. Fishing gear is lost by both ... -
Lobster and cod benefit from small-scale northern marine protected areas : inference from an empirical before - after control-impact study
Moland, Even; Olsen, Esben Moland; Knutsen, Halvor; Garrigou, Pauline; Espeland, Sigurd Heiberg; Kleiven, Alf Ring; André, Carl; Knutsen, Jan Atle (Journal article; Peer reviewed, 2013)Marine protected areas (MPAs) are increasingly implemented as tools to conserve and manage fisheries and target species. Because there are opportunity costs to conservation, there is a need for science-based assessment of ... -
