Abstract:
The relevance of the study is conditioned by the defining role of the stage of early
development in the ontogenesis of young fish in the formation of their growth rate potential.
The physiological and biochemical status of the body determines the adaptive capabilities of hydrobionts, so the use of biologically active substances when rearing fish was chosen as one of
the vectors for improving the development parameters. The purpose of the study was to determine
the effectiveness of introducing technological elements (supplementary feeding, rearing) in the early stages of the ontogenesis of young fish. The study was based on theoretical (analysis, synthesis, comparison, modelling), experimental, and laboratory methods adopted in fisheries, physicochemical studies. A clinical examination of fish, monitoring of growth rates, weight gain, survival rate, and physiological state was carried out.
