Study of the influence of fish feeding on the example of carp (Cyprinus carpio L.) under conditions of chemical pollution of the aquatic environment

The study of the influence of chemicals in the aquatic environment on the nutrition of fish, which lead to gradual pollution of the aquatic environment and violation of living conditions, and the development of methods for improving the nutritional properties of fish, which is an important branch of science that combines fish biology, in-depth study of nutrition and rational management, has been established fish resources and environmental sustainability. In recent years, a significant amount of research has been conducted aimed at understanding the relationships between fish nutrition, their development and the quality of fish products, the influence of chemicals on these processes in today's conditions using the example of carp (Cyprinus carpio L.). Analyzing the data, it was found that the quality of fish nutrition depends on the quality and composition of water, which affects the growth, development and health of fish. Considering the requirements of nutrients such as proteins, fats, vitamins and minerals, good nutrition can improve the quality of fish production. Special attention is paid to the role of proteins in the metabolism of fish using the example of cyprinus carp (Cyprinus carpio L.), growth and development, as well as adaptation to the interesting study of the composition of tissue proteins of carp during cadmium and lead intoxication. This year's carp (Cyprinus carpio L.), which is a widespread object of pond culture in Ukraine, was used for the experiment. A detailed analysis indicates that taking into account the effect of toxic substances on fish nutrition is necessary to ensure their health and optimal fish production. The development of new feeding strategies and the use of special additives is becoming a key aspect not only for improving the quality of products, but also for ensuring compliance with safety standards and environmental sustainability in the field of aquaculture and fisheries. Such research identifies new ways to create sustainable and healthy fish populations, contributing to the coordinated development of the agro-industrial sector and the preservation of aquatic ecosystems.
