Modern fish farming is one of the key branches of aquaculture, providing the population with high-quality protein products of animal origin. Effective freshwater fish farming is impossible without a deep understanding of fish biology, the patterns of their growth, development, feeding, and reproduction. The relevance of studying these aspects is determined by the need to increase the productivity of water bodies, optimize rearing technologies, and preserve the biodiversity of aquatic ecosystems.
The biology of freshwater fish encompasses a wide range of issues — from morphology and physiology to behavior and adaptations to different habitats. Particular importance is given to the study of growth processes, metabolism, reproduction, and responses to environmental factors. Growth rate and feed conversion efficiency depend on the fish species, water temperature, oxygen concentration, chemical composition of the environment, and feeding level.
The study of biological characteristics allows the formation of species-specific maintenance regimes, determination of optimal feeding parameters, and development of methods to stimulate growth. Growth and development rates are closely related to water quality. Temperature, dissolved oxygen, concentrations of ammonia, nitrites and nitrates, and pH are key parameters determining the physiological state of fish. In particular, oxygen deficiency leads to hypoxia, reduced appetite, and slower metabolism, whereas optimal conditions promote intensive growth and lower mortality rates.
