Instar growth and molt increments in Lepeophtheirus salmonis (Copepoda: Caligidae) chalimus larvae
(Peer reviewed; Journal article, 2015-02)The salmon louse (Lepeophtheirus salmonis) is an ectoparasitic copepod causing severe problems to the fish farming industry and to wild salmonids. Morphologically, all stages in the life cycle of L. salmonis have been ... -
Iodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
(Peer reviewed; Journal article, 2013-02-19)Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential ... -
A new aquareovirus causing high mortality in farmed Atlantic halibut fry in Norway
(Peer reviewed; Journal article, 2015-01)A new aquareovirus was isolated from cultured Atlantic halibut (Hippoglossus hippoglossus) fry at a facility where massive mortalities had occurred during the start-feeding phase. The same virus was also detected in juveniles ... -
Redox regulation in Atlantic cod (Gadus morhua) embryos developing under normal and heat-stressed conditions
(Peer reviewed; Journal article, 2013-04)With regard to predicted oceanic warming, we studied the effects of heat stress on the redox system during embryonic development of Atlantic cod (Gadus morhua), with emphasis on the glutathione balance, activities of key ... -
Thermal plasticity in farmed, wild and hybrid Atlantic salmon during early development: Has domestication caused divergence in low temperature tolerance?
(Peer reviewed; Journal article, 2016-02-16)Background: In the past three decades, millions of domesticated Atlantic salmon Salmo salar L. have escaped from farms into the wild. Their offspring display reduced survival in the natural environment, which demonstrates ... -
