Comparison of the effect of dichlorvos and pyrethrins against salmon lice (Lepeophtheirus salmonis) parasitic on salmon (Salmo salar) by one or successive treatments
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 tested and in this report a bath exposure to the treatment solution has been used. D...
