A Comparative Study of the Spawning Phenology of Cod (Gadus morhua), Saithe (Pollachius virens), and Haddock (Melanogrammus aeglefinus): a Geographical Perspective along the Norwegian Coast
(Master thesis, 2023-06-02)Reproductive traits are a fundamental aspect of an organism's life history and play a critical role in shaping population dynamics, as these traits can significantly influence offspring survival rates and, thereby, ... -
Energy dilution with α-cellulose in diets for Atlantic cod (Gadus morhua L.) juveniles - effects on growth, feed intake, liver size and digestibility of nutrients
(Master thesis, 2009-05-03)Atlantic cod (Gadus morhua) is known to grow large livers, especially farmed cod, but commercially, muscle growth is preferred, due to profits. Therefore, main focus in this feeding trial was to achieve lowered liver size, ... -
Enrichment promotes learning in fish
(Peer reviewed; Journal article, 2010-08-18)Captive birds and mammals reared in enriched rearing environments have been shown to behave more flexibly compared to animals reared in impoverished or plain environments. Recent evidence has shown that this is also true ... -
Environmental variability in the early rearing environment generates behaviourally flexible cod: implications for rehabilitating wild populations
(Peer reviewed; Journal article, 2005-06-02)The release of hatchery-reared fishes for restoring threatened and endangered populations is one of the most controversial issues in applied ecology. A central issue has been to determine whether releases cause extinction ... -
Is individual variation in competitive performance of reared juvenile cod influenced by haemoglobin genotype?
(Peer reviewed; Journal article, 2000)To succeed in scramble competition for food an individual fish will have to have characteristics that allow it to respond rapidly to encountered prey. A trait such as metabolic rate, which has a positive effect on oxygen ... -
Quantification and localization of StAR expression in Atlantic cod ovaries
(Master thesis, 2009-06-02)Steroidogenesis is essential for the production of sex steroids, and therefore also the sexual maturation process. The rate-limiting step in steroidogenesis is the movement of cholesterol from the outer to the inner ...
