Allometric growth and development of organs in ballan wrasse (Labrus bergylta Ascanius, 1767) larvae in relation to different live prey diets and growth rates
Kjørsvik, Elin; Gagnat, Maren Ranheim; Bardal, Tora; Wold, Per-Arvid; Øie, Gunvor (Journal article; Peer reviewed, 2016)Small fish larvae grow allometrically, but little is known about how this growth pattern may be affected by different growth rates and early diet quality. The present study investigates how different growth rates, caused ... -
An oil containing EPA and DHA from transgenic Camelina sativa to replace marine fish oil in feeds for Atlantic salmon (Salmo salar L.): Effects on intestinal transcriptome, histology, tissue fatty acid profiles and plasma biochemistry
Betancor, Monica B; Li, Keshuai; Sprague, Matthew; Bardal, Tora; Sayanova, Olga; Usher, Sarah; Han, Lihua; Måsøval, Kjell; Torrissen, Ole; Napier, Johnathan; Tocher, Douglas R.; Olsen, Rolf Erik (Journal article; Peer reviewed, 2017)New de novo sources of omega 3 (n-3) long chain polyunsaturated fatty acids (LC-PUFA) are required as alternatives to fish oil in aquafeeds in order to maintain adequate levels of the beneficial fatty acids, eicosapentaenoic ... -
Developmental effects in fish embryos exposed to oil dispersions – the impact of crude oil micro-droplets
Hansen, Bjørn Henrik; Salaberria, Iurgi; Read, Kari; Wold, Per-Arvid; Hammer, Karen Marie; Olsen, Anders Johny; Altin, Dag; Øverjordet, Ida Beathe; Nordtug, Trond; Bardal, Tora; Kjørsvik, Elin (Journal article; Peer reviewed, 2019)During accidental crude oil spills and permitted discharges of produced water into the marine environment, a large fraction of naturally occurring oil components will be contained in micron-sized oil droplets. Toxicity is ... -
Digestive Tract and the Muscular Pharynx/Esophagus in Wild Leptocephalus Larvae of European Eel (Anguilla anguilla)
Knutsen, Helene Rønquist; Sørensen, Sune Riis; Munk, Peter; Bardal, Tora; Kjørsvik, Elin (Peer reviewed; Journal article, 2021)Several aspects of the biology of European eel (Anguilla anguilla) larvae are still unknown; particularly, information about their functional development and feeding is sparse. In the present study, we histologically ... -
Intestinal health in Atlantic salmon post-smolt (Salmo salar) when fed low- and high HUFA diets
Løvmo, Signe Dille; Sundh, Henrik; Whatmore, Paul; Nordvi, Malene Fosse; Sigholt, Trygve; Madaro, Angelico; Bardal, Tora; Olsen, Rolf Erik (Peer reviewed; Journal article, 2022)It is well established that farmed Atlantic salmon (Salmo salar) need n3-highly unsaturated fatty acids (HUFA) in their diet to thrive and grow. However, the biological functions to the individual HUFAs may differ, implying ... -
Mid and hindgut transcriptome profiling analysis of Atlantic salmon (Salmon salar) under unpredictable chronic stress
Løvmo, Signe Dille; Madaro, Angelico; Whatmore, Paul; Bardal, Tora; Østensen, Mari-Ann; Sandve, Simen Rød; Olsen, Rolf Erik (Peer reviewed; Journal article, 2020)The intestinal epithelium is a selectively permeable barrier for nutrients, electrolytes and water, while maintaining effective protection against pathogens. Combinations of stressors throughout an animal's life, especially ... -
OC2017 A-029 - Vannkvalitet og startfôring av rognkjeks - Effekt av fôring med levende copepoder i tidlige faser (FHF prosjekt nr 901174)
Dahle, Stine Veronica Wiborg; Hagemann, Andreas; Attramadal, Kari; Kjørsvik, Elin; Bardal, Tora (Research report, 2017)I oppdrett av rognkjeks benyttes fonnulert tønfor av små partikler fra start, som gir mye forspill i karene. Høy og varierende organisk belastning i systemet gir grobunn for oppblomstring av opportunistiske bakterier ... -
Quality of Atlantic Cod Frozen in Cell Alive System, Air-Blast, and Cold Storage Freezers
Erikson, Ulf Gøran; Kjørsvik, Elin; Bardal, Tora; Digre, Hanne; Schei, Marte; Søreide, T.; Aursand, Ida Grong (Journal article; Peer reviewed, 2016)Gutted Atlantic cod, packed in cartons, were frozen immediately after killing in a magnetic field (cell alive system). The results were compared with traditional air-blast freezing or by putting the cartons directly in a ... -
Skeletal muscle growth dynamics and the influence of first-feeding diet in Atlantic cod larvae (Gadus morhua L.)

The digestive system of ballan wrasse (Labrus bergylta), a marine agastric carnivorous teleost
Flaten, Steinar (Master thesis, 2021)The knowledge of the digestive system of teleosts is limited, especially when considering the huge variation in morphology. There are particularly few studies of the digestive system of agastric (stomachless) teleosts such ...
