Lota lota is the only gadiform (cod-like) freshwater fish. L. lota populations are difficult to study due to their deep habitats and reproduction under ice. There is limited information about this species in the wild and under farming conditions. As L. lota lacks popularity in commercial fishing, many regions do not even consider management plans. Aquaculture could represent a solution to restore L. lota wild populations. In the recent years, it has become one of the promising candidates for diversification of freshwater aquaculture. Further research is needed on both natural behaviour and physiological effects of farming practices in order to provide recommendations for improving fish welfare.
