Biochemical composition of copepods for evaluation of feed quality in production of juvenile marine fish
van der Meeren, Terje; Olsen, Rolf Erik; Hamre, Kristin; Fyhn, Hans Jørgen (Journal article; Peer reviewed, 2007-12-13)To increase current knowledge on the nutritional value of natural prey organisms, the biochemical components of mainly three copepods (Acartia grani, Centropages hamatus, and Eurytemora affinis) from a marine pond system ... -
Differential processing of yolk proteins during oocyte hydration in marine fishes (Labridae) that spawn benthic and pelagic eggs
Finn, Roderick Nigel; Wamboldt, Melissa; Fyhn, Hans Jørgen (Journal article; Peer reviewed, 2002-07-18)The yolk proteins and free amino acids (FAA) were investigated during oocyte maturation in 4 species of Labridae with either benthic or pelagic eggs. Benthic eggs and oocytes of both types had a small FAA pool dominated ... -
Fuel and metabolic scaling during the early life stages of Atlantic cod Gadus morhua
Finn, Roderick Nigel; Rønnestad, Ivar; van der Meeren, Terje; Fyhn, Hans Jørgen (Journal article; Peer reviewed, 2002-11-13)The simultaneous effect of temperature (5, 7, 10 and 13degreesC) and light on the rates of oxygen consumption and ammonia excretion of larval and early juvenile Atlantic cod Gadus morhua was examined. Larvae increased their ... -
Size of spawning Arcto-Norwegian cod (Gadus morhua L.) and the effects on their eggs and early larvae
Solemdal, Per; Bergh, Øivind; Dahle, Geir; Falk-Petersen, Inger-Britt; Fyhn, Hans Jørgen; Grahl-Nielsen, Otto; Haaland, J.M.; Kjesbu, Olav Sigurd; Løken, Sissel; Opstad, Ingegjerd; Pedersen, Torstein; Skiftesvik, Anne Berit; Thorsen, Anders (ICES CM Documents;1993/G:41, Working paper, 1993)Using a new method for determining the stage of spawning in batch spawners, a positive correlation between the length of Arcto-Norwegian cod females, having spawned 25-75% of their eggs, and the egg diameter was established. ... -
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 ...
