Scientific and methodological approaches and experience of breeding Arctic char on the example of factory cultivation of Ladoga palia Salvelinus lepechini (Gmelin 1788)

Based on the long-term experience of keeping Ladoga palia in factory conditions, methodological approaches to the reproduction of this species and a scheme for its cultivation are proposed, which can be used as a basis for breeding Arctic char in fish hatcheries. The characteristics of the object of research and the prospects of its use in aquaculture are given. The features of the development of embryos and larvae are considered. The scheme of formation and operation of repair-brood herds of Ladoga palia is proposed. The criteria for selecting producers for repair and breeding herds are substantiated.
