A comparative study of diploid versus triploid Atlantic salmon (Salmo salar L.). The effects of rearing temperatures (5, 10 and 15 °C) on raw material characteristics and storage quality
Lerfall, Jørgen; Hasli, Pål Rune; Skare, Even Flønes; Olsen, Rolf Erik; Rotabakk, Bjørn Tore; Roth, Bjørn; Slinde, Erik; Egelandsdal, Bjørg Tordis (Peer reviewed; Journal article, 2017) -
Assessing the effectiveness of an electrical stunning and chilling protocol for the slaughter of Atlantic mackerel (Scomber scombrus)
Anders, Neil; Roth, Bjørn; Grimsbø, Endre; Breen, Michael (Journal article; Peer reviewed, 2019)Inducing unconsciousness in fish using electrical stunning prior to slaughter may improve fish welfare and fillet quality if such practises can be disseminated into wild capture fisheries. The objectives of this study were ... -
Effects of capture-related stress and pre-freezing holding in refrigerated sea water (RSW) on the muscle quality and storage stability of Atlantic mackerel (Scomber scombrus) during subsequent frozen storage
Anders, Neil; Breen, Michael; Skåra, Torstein; Roth, Bjørn; Sone, Izumi (Peer reviewed; Journal article, 2022)Crowded (stressed) and unstressed Atlantic mackerel with or without pre-freezing holding in refrigerated sea water (RSW) were stored at −19 °C for ∼12 months and analysed for nucleotide degradation (K value), muscle pH, ... -

Anders, Neil; Breen, Michael; Skåra, Torstein; Roth, Bjørn; Sone, Izumi (Peer reviewed; Journal article, 2024)Crowded (stressed) and unstressed Atlantic mackerel with or without pre-freezing holding in refrigerated sea water (RSW) were stored at −19 °C for ∼12 months and analysed for nucleotide degradation (K value), muscle pH, ... -
Flesh quality of Atlantic salmon smolts reared at different temperatures and photoperiods
Imsland, Albert; Roth, Bjørn; Døskeland, Inge; Fjelldal, Per Gunnar; Stefansson, Sigurd Olav; Handeland, Sigurd O; Mikalsen, Bjørn (Journal article; Peer reviewed, 2019)Possible interactive effects of temperature and photoperiod on flesh quality in Atlantic salmon post‐smolts were studied. Juvenile (initial mean weight 96.0 g ± 3.1 SEM) Atlantic salmon were reared at six different ... -

Gjenfangst av rensefisk er ... -
Physiological and flesh quality consequences of pre-mortem crowding stress in Atlantic mackerel (Scomber scombrus)
Anders, Neil; Eide, Ida; Lerfall, Jørgen; Roth, Bjørn; Breen, Michael (Peer reviewed; Journal article, 2020)In commercial wild capture pelagic fisheries it is common practice to crowd catches to high densities to allow efficient pumping onboard. Crowding during the final stages of purse seine capture for small pelagic species ... -
Physiological response and survival of Atlantic mackerel exposed to simulated purse seine crowding and release
Anders, Neil; Roth, Bjørn; Breen, Mike (Peer reviewed; Journal article, 2021)Understanding how animals physiologically respond to capture and release from wild capture fishing is fundamental for developing practices that enhance their welfare and survival. As part of purse seine fishing for small ... -
Small-Scale Comparative Genomic Analysis of Listeria monocytogenes Isolated from Environments of Salmon Processing Plants and Human Cases in Norway
Løvdal, Trond Karsten; Brandal, Lin Cathrine T.; Sundaram, Arvind; Naseer, Umaer; Roth, Bjørn; Lunestad, Bjørn Tore (Journal article, 2021)Listeria monocytogenes is a food-borne bacterium that give rise to the potentially life-threatening disease listeriosis. Listeriosis has been mandatorily notifiable in Norway since 1991. All clinical L. monocytogenes ... -
