Chauton, Matilde Skogen; Galloway, Trine Falck; Kjørsvik, Elin; Størseth, Trond Røvik; Puvanendran, Velmurugu; van der Meeren, Terje; Karlsen, Ørjan; Rønnestad, Ivar; Hamre, Kristin (Journal article, 2015)Marine aquaculture offers a great source of protein for the increasing human population, and farming of, for example, Atlantic salmon is a global industry. Atlantic cod farming however, is an example of a promising industry ... -
Can lipidomics help identifying egg quality in ballan wrasse?
Malzahn, Arne; Sarno, Antonio; Hagemann, Andreas; Farkas, Julia; Musialak, Luciana Alves; Kjørsvik, Elin; Hansen, Bjørn Henrik (Peer reviewed; Journal article, 2022)Ballan wrasse (Labrus bergylta) is in the limelight of aquaculture research due to the species role as cleaner fish in salmon aquaculture. A major drawback is that the salmon industry still depends on wild caught fish as ... -
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 Sverre; Hammer, Karen Marie; Olsen, Anders Johny; Altin, Dag; Øverjordet, Ida Beathe; Nordtug, Trond; Bardal, Tora; Kjørsvik, Elin (Journal article; Peer reviewed, 2019-09)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 ... -
Effect of diet on molecular relationships between Atlantic cod larval muscle growth dynamics, metabolism, and antioxidant defense system
Vo, Tu Anh; Galloway, Trina Falck; Arukwe, Augustine; Edvardsen, Rolf Brudvik; Hamre, Kristin; Karlsen, Ørjan; Rønnestad, Ivar; Kjørsvik, Elin (Peer reviewed; Journal article, 2022)We studied molecular effects (RNAseq and qPCR) of first feeding prey types (copepods or rotifers/Artemia) on skeletal muscle myogenesis and growth dynamics (proliferation, differentiation), metabolism (glycolysis, ... -
First feed matters: The first diet of larval fish programmes growth, survival, and metabolism of larval ballan wrasse (Labrus bergylta)
Malzahn, Arne; Ribicic, Deni; Hansen, Bjørn Henrik; Sarno, Antonio; Kjørsvik, Elin; Aase, Anna Sigrid Nordberg; Alves Musialak, Luciana; Garcia Calvo, Laura; Hagemann, Andreas (Peer reviewed; Journal article, 2022)The use of cleaner fish, such as the ballan wrasse (Labrus bergylta), is important for combatting the sea lice problem in salmonid cage farming. Ballan wrasse is the only wrasse species that is cultivated, though only about ... -
The impact of exposure timing on embryo mortality and the partitioning of PAHs when cod eggs are exposed to dispersed and dissolved crude oil
Nordtug, Trond; Olsen, Anders Johny; Wold, Per-Arvid; Salaberria, Iurgi; Øverjordet, Ida Beathe; Altin, Dag; Kjørsvik, Elin; Hansen, Bjørn Henrik (Peer reviewed; Journal article, 2022)During sub-sea oil spills to the marine environment, oil droplets will rise towards the sea surface at a rate determined by their density and diameter as well as the vertical turbulence in the water. Micro-droplets (< 50 ... -
Ova lipid profiling and egg quality in wild and captive lumpfish, Cyclopterus lumpus (Linnaeus, 1758)
Hansen, Bjørn Henrik; Kjørsvik, Elin; Malzahn, Arne; Sarno, Antonio; Kulild, Ole Martin; Farkas, Julia; Nordtug, Trond; Rye, Rebecca; Kvæstad, Bjarne; Lein, Ingrid; Hagemann, Andreas (Peer reviewed; Journal article, 2022)Lumpfish (Cyclopterus lumpus) serves an important role as cleaner fish for removing salmon lice in salmon aquaculture. For this use, cultivated lumpfish are preferred over wild-caught fish to avoid overexploitation of ... -
