In Sweden, many European grayling, Thymallus thymallus, populations have decreased owing to freshwater acidification, water-flow regulation and overfishing. Thus there is an increasing demand for production of grayling for stocking purposes. Knowledg

Four artificial, dry feeds and two diets consisting of natural, live food were evaluated for use as starter diets in the intensive rearing of European grayling (Thymallus thymallus). Long-term effects of the different diets were also studied. The inv
