1H NMR metabolic profiling of cod (Gadus morhua) larvae: potential effects of temperature and diet composition during early developmental stages
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; Peer reviewed, 2015-11-06)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 ... -
A preliminary note on the ecology of eggs and larvae of the Atlantic halibut (Hippoglossus hippoglossus)
Haug, Tore; Kjørsvik, Elin; Sundet, Jan H. (ICES CM Documents;1982/G:9, Working paper, 1982) -
Copepods enhance nutritional status, growth and development in Atlantic cod (Gadus morhua L.) larvae – can we identify the underlying factors?
Karlsen, Ørjan; van der Meeren, Terje; Rønnestad, Ivar; Mangor-Jensen, Anders; Galloway, Trine Falck; Kjørsvik, Elin; Hamre, Kristin (Journal article; Peer reviewed, 2015-05-19)The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were ... -
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, ... -
Influence of some physical and biological factors on the density and vertical distribution of Atlantic halibut Hippoglossus hippoglossus eggs
Haug, Tore; Kjørsvik, Elin; Solemdal, Per (Journal article; Peer reviewed, 1986-10-27)ACT: Atlantic halibut Hippoglossus hippoglossus (L.) eggs were sampled using a Tucker trawl and a MOCNESS-sampler at 3 selected localities in North Norway. The specific density of the eggs was determined in a density-gradient ... -
Morphological, psychological and genetical studies of egg quality in cod (Gadus morhua L.). In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
Kjørsvik, Elin; Stene, Anne; Lønning, Sunniva (Flødevigen Rapportserie, Conference object, 1984)The development of cod eggs from various parent fishes was studied. Fertilization success, and proportion of normally developing embryos and larvae varied according to the quality of the eggs. Eggs from poor quality cultures ... -
The effects of maternal status of Arcto-Norwegian cod on egg quality and vitality of early larvae. 1. The collection and characteristics of the cod females, a pilot study
Solemdal, Per; Kjesbu, Olav Sigurd; Kjørsvik, Elin (ICES CM Documents;1992/G:78, Working paper, 1992)On the basis of a new field method to determine the stage of spawning, egg groups from Arcto-Norwegian cod females in different stage of spawning were selected for further studies on egg quality and vitality of early ... -
The effects of maternal status of Arcto-Norwegian cod on egg quality and vitality of early larvae. 2. Preliminary results of the experiment in 1992
Solemdal, Per; Bergh, Øivind; Finn, Roderick Nigel; Fyhn, Hans Jørgen; Grahl-Nielsen, Otto; Homme, O.; Kjesbu, Olav Sigurd; Kjørsvik, Elin; Opstad, Ingegjerd; Skiftesvik, Anne Berit (ICES CM Documents;1992/G:79, Working paper, 1992)The stage of spawning of females of the Arcto-Norwegian cod caught during peak spawning in Lofoten had a profound effect on several vital parameters of the eggs and larvae. Significant negative correlations were ...
