Evaluating the effect of dorsal muscle biopsies on adult Atlantic salmon growth and marine return rates
Abstract Increasing conservation and animal-welfare concerns have driven the development of non-lethal sampling of fish populations, with the use of muscle tissue biopsies now being routinely applied as a sampling method in the wild.
