Farming remarks

Thymallus thymallus is reared for re-stocking and for feeding purposes. It is a highly appreciated species for sports fishing in northern Europe, where several initiatives have been undertaken for conservation of endangered populations. Its breeding in aquaculture relies mostly on wild parents, and many aspects of its rearing remain undisclosed. In addition, several welfare issues are probably not addressed so further research should focus mainly on substrate needs and stress effects of farming, spatial needs, reproduction without manipulation, aggregation, aggression, territoriality, and humane slaughtering.
