A pilot study of halibut larvae (Hippoglossus hippoglossus L.) reared from start feeding to metamorphosis on diets of wild zooplankton and Artemia
Boxaspen, Karin; Harboe, Torstein; Skjolddal, Lillian (ICES CM Documents;1990/F:52, Working paper, 1990)Halibut larvae ready to start feed were placed in two outdoor tanks of 7 m^3. The larvae in one tank were fed wild zooplankton throughout the whole period, and the larvae in the other tank were fed wild zooplankton from ... -
Comparison of the effect of dichlorvos and pyrethrins against salmon lice (Lepeophtheirus salmonis) parasitic on salmon (Salmo salar) by one or successive treatments
Boxaspen, Karin (ICES CM Documents;1994/F:21, Working paper, 1994)Experiments with a flower extract containing Pyrethrins generally used as an insecticide has been carried out at Austevoll Aquaculture Research Station since 1989. Different types of administration methods have been ... -
Infection success of salmon lice related to temperature and implications for regional size of salmon production areas
Boxaspen, Karin (ICES CM Documents;2002/T:1, Working paper, 2002)The development rate for salmon lice larvae is highly temperature-dependent. Hence, the time from hatching of nauplii to an infectious copepodid will vary with the natural cycles in the sea. The salmon lice life span is ... -
Modelled distribution of salmon lice in a Norwegian fjord
Asplin, Lars; Boxaspen, Karin; Sandvik, Anne Dagrun (ICES CM documents, Working paper, 2004)Salmon lice is a huge problem for both wild and farmed salmonid fish in fjords. An assessment of salmon lice in a fjord system will bring forward the knowledge of wild salmonid fish stocks and help manage salmonid fish ...
