Profitable Arctic charr farming in the Nordic countries
The present study evaluated these earlier findings under practical conditions in commercial aquaculture production, to verify the results of the laboratory trials.Reduced protein content was combined with high fishmeal substitution in diets and the diets tested as compared to the commercial diets us...

The present study evaluated these earlier findings under practical conditions in commercial aquaculture production, to verify the results of the laboratory trials.Reduced protein content was combined with high fishmeal substitution in diets and the diets tested as compared to the commercial diets used by partners in the three Nordiccountries involved.
