Atlantic cod (Gadus morhua) larvae are attracted by low-frequency noise simulating that of operating offshore wind farms
Cresci, Alessandro; Zhang, Guosong; Durif, Caroline; Larsen, Torkel; Shema, Steven; Skiftesvik, Anne Berit; Browman, Howard (Peer reviewed; Journal article, 2023)The number and size of offshore wind (OW) turbines is increasing rapidly. OW turbines produce continuous, low-frequency noise that could impact marine fish dispersing/migrating through the facilities. Any such impact would ... -
Goldsinny wrasse (Ctenolabrus rupestris) have a sex-dependent magnetic compass for maintaining site fidelity
Cresci, Alessandro; Larsen, Torkel; Halvorsen, Kim Aleksander Tallaksen; Durif, Caroline; Bjelland, Reidun Marie; Browman, Howard; Skiftesvik, Anne Berit (Peer reviewed; Journal article, 2021)The goldsinny wrasse (Ctenolabrus rupestris) is a commercially important fish that inhabits coastal areas across the eastern Atlantic. This species moves from a shallow home territory along the coast into deeper waters in ... -
Kunnskapsbasert innovasjon for optimal ressursutnyttelse i leppefiskeriet — Sluttrapport i prosjekt 272202 - Regionalt forskningsfond Agder
Halvorsen, Kim Aleksander Tallaksen; Sørdalen, Tonje Knutsen; Larsen, Torkel; Rafoss, Trond; Skiftesvik, Anne Berit (Rapport fra havforskningen;2020 - 3, Research report, 2020)Rensefisk benyttes for å kontrollere mengden lakselus i oppdrett av laksefisk i sjø i Norge. Behovet for rensefisk har økt markant siden 2010 på grunn av resistensutvikling mot medikamentelle behandlinger hos lakselus ... -
Kunnskapsinnhenting Leppefisk – biologi og fiskeri 2013-2018: Rapport til Fiskeridirektoratet for 2018 sesongen
Skiftesvik, Anne Berit; Halvorsen, Kim Aleksander Tallaksen; Larsen, Torkel (Rapport fra havforskningen;2019 - 18, Research report, 2019) -
Kunnskapsstøtte og råd for regulering av fisket etter leppefisk i 2022
Halvorsen, Kim Aleksander Tallaksen; Skiftesvik, Anne Berit; Larsen, Torkel; Otterå, Håkon Magne; Fernández-Chacón, Albert (Rapport fra havforskningen;2021 - 54, Research report, 2021)Havforskningsinstituttets råd om reguleringer av leppefisk har bygget på føre-var-prinsippet. Det er en målsetning å minimere risikoen for at fiskeriet fører til betydelige endringer i arts, størrelse- og kjønnssammensetning ... -
Kunnskapstøtte og råd for regulering av fisket etter leppefisk i 2021
Halvorsen, Kim Aleksander Tallaksen; Skiftesvik, Anne Berit; Bjelland, Reidun Marie; Larsen, Torkel (Rapport fra havforskningen;2020 - 51, Research report, 2020)Fiskeridirektoratet har i en bestilling datert 07.09.2020 bedt Havforskningsinstituttet (HI) om kunnskapsstøtte for regulering av totaluttak, fartøykvoter, artsbegrensninger i fisket etter leppefisk. Det bes også om ny ... -
Magnetic fields generated by the DC cables of offshore wind farms have no effect on spatial distribution or swimming behavior of lesser sandeel larvae (Ammodytes marinus)
Cresci, Alessandro; Perrichon, Prescilla; Durif, Caroline; Sørhus, Elin; Johnsen, Espen; Bjelland, Reidun Marie; Larsen, Torkel; Skiftesvik, Anne Berit; Browman, Howard (Peer reviewed; Journal article, 2022)In the North Sea, the number and size of offshore wind (OW) turbines, together with the associated network of High Voltage Direct Current (HVDC) subsea cables, will increase rapidly over the coming years. HVDC cables produce ... -
Mind the depth: The vertical dimension of a small-scale coastal fishery shapes selection on species, size, and sex in wrasses
Halvorsen, Kim Aleksander Tallaksen; Sørdalen, Tonje Knutsen; Larsen, Torkel; Browman, Howard; Rafoss, Trond; Albretsen, Jon; Skiftesvik, Anne Berit (Peer reviewed; Journal article, 2020)Small‐scale fisheries (SSFs) tend to target shallow waters, but the depth distributions of coastal fish can vary depending on species, size, and sex. This creates a scope for a form of fishing selectivity that has received ... -
Movement patterns of temperate wrasses (Labridae) within a small marine protected area
Halvorsen, Kim Aleksander Tallaksen; Larsen, Torkel; Browman, Howard; Durif, Caroline; Aasen, Nicolai; Vøllestad, Leif Asbjørn; Cresci, Alessandro; Sørdalen, Tonje Knutsen; Bjelland, Reidun Marie; Skiftesvik, Anne Berit (Peer reviewed; Journal article, 2021)The movement patterns of three commercially important wrasse (Labridae) species inside a small marine protected area (~ 0.15 km2) on the west coast of Norway were analysed over a period of 21 months. The mean distance ... -
