Bifangst av sjøfugl i kystnært notfiske – utvikling og testing av avbøtende tiltak - Tokt med MS "Vestbris" 6 - 10.1.2024
Tenningen, Maria; Saltskår, Jostein; Bærum, Kim Magnus; Molværsmyr, Sindre; Christensen-Dalsgaard, Signe (Toktrapport;2024 - 17, Research report, 2024)Notfiskeriene tiltrekker store mengder sjøfugler som beiter på fisken som blir samlet sammen i nøtene og er lett tilgjengelig for fuglene. Dette kan føre til uheldige interaksjoner der sjøfugl blir tatt som bifangst. Det ... -
Bycatch of northern fulmar (Fulmarus glacialis) in Norwegian longline fisheries: Assessing spatiotemporal variations in scale and risk to improve management
Clegg, Tom L.; Christensen-Dalsgaard, Signe; Bråthen, Vegard Sandøy; Tarroux, Arnaud; Danielsen, Jóhannis; Descamps, Sebastien; Follestad, Arne; Hallgrimsson, Gunnar Thor; Helberg, Morten; Helgason, Hálfdán H.; Jónsson, Jón Einar; Kolbeinsson, Yann; Strøm, Hallvard; Thompson, Paul; Thórarinsson, Thorkell Lindberg; Williams, Tom; Bærum, Kim Magnus (Peer reviewed; Journal article, 2024)Seabirds are vulnerable to bycatch in longline fisheries but for most species the impacts are largely unknown. To address this knowledge gap, studies can estimate bycatch directly using observations or calculate the ... -

Sharing the neighbourhood: assessing the impact of kelp harvest on foraging behaviour of the European shag
Christensen-Dalsgaard, Signe; Mattisson, Jenny; Norderhaug, Kjell Magnus; Lorentsen, Svein Håkon (Peer reviewed; Journal article, 2020)Coastal kelp forest ecosystems create dynamic and productive habitats, supporting a wide range of epiphytic flora, invertebrates, fish and seabirds. Worldwide, kelp is harvested commercially, affecting kelp-associated ... -
Spatial and temporal variations in seabird bycatch: Incidental bycatch in the Norwegian coastal gillnet-fishery
Bærum, Kim Magnus; Anker-Nilssen, Tycho; Christensen-Dalsgaard, Signe; Fangel, Kirstin; Williams, Tom; Vølstad, Jon Helge (Peer reviewed; Journal article, 2019)The general decline of seabird populations worldwide raises large concerns. Although multiple factors are interacting to cause the observed trends, increased mortality from incidental bycatch in fisheries has proven to be ...
