Farming remarks
The production of Oncorhynchus masou has emerged over the past decades mainly to supplement wild populations and increase fisheries. The low WelfareScore is mainly due to home range needs, high levels of aggression, needs of substrate, stress under farming conditions, and high levels of deformations.
Despite the availability of many studies about the life history and environmental conditions of Salmonids in general, there is limited information on present farming conditions of Oncorhynchus masou. Further research is needed on both natural behaviour and physiological effects of farming practices in order to provide recommendations for improving fish welfare. In addition, the impact of releasing captive IND in the dynamic of the wild populations needs clarifications in order to use the restocking programmes more appropriately and effectively.
