A novel probabilistic survey method for at sea sampling in pelagic fisheries – the Norwegian catch sampling lottery
Otterå, Håkon Magne; Wathne, Jens A.; Fuglebakk, Edvin; Slotte, Aril; Svendsen, Bjørn Vidar; Vølstad, Jon Helge (Peer reviewed; Journal article, 2022)Reliable information on the age- and size-structure of the annual harvest of major commercial fish stocks is crucial input to analytical stock assessments. Such information is usually obtained from landing data (census of ... -
Poleward spawning of Atlantic mackerel (Scomber scombrus) is facilitated by ocean warming but triggered by energetic constraints
dos Santos Schmidt, Thassya Christina; Slotte, Aril; Olafsdottir, Anna H.; Nøttestad, Leif; Jansen, Teunis; Jacobsen, Jan Arge; Bjarnason, Sigurvin; Lusseau, Susan Mærsk; Ono, Kotaro; Hølleland, Sondre Nedreås; Thorsen, Anders; Sandø, Anne Britt; Kjesbu, Olav Sigurd (Peer reviewed; Journal article, 2023)The Northeast Atlantic mackerel is an income breeder with indeterminate fecundity, spawning in multiple batches at optimal temperatures around 11°C in the upper water column during February–July along the continental shelf ... -
Predicting density-dependent somatic growth in Norwegian spring-spawning herring
Stenevik, Erling Kåre; Hølleland, Sondre Nedreås; Enberg, Katja; Høines, Åge Sigurd; Salthaug, Are; Slotte, Aril; Vatnehol, Sindre; Aanes, Sondre (Peer reviewed; Journal article, 2022)Density-dependent growth, which might influence the effects of fisheries on a population, is often ignored when management strategies are evaluated, mainly due to a lack of appropriate models readily available to be ... -

Slotte, Aril; Skagen, Dankert W.; Iversen, Svein A. (Journal article; Peer reviewed, 2007-04)In September after summer feeding has ceased, Northeast Atlantic mackerel (Scomber scombrus) tend to aggregate in ICES Area IVa before starting to migrate south towards the spawning grounds, between December and February. ... -
