Abstract
The protection of fishery waters from pollution caused by toxicants is one of the urgent problems in the development of fisheries. The article presents the results of studying the dynamics of the content of heavy metals in the pond water of a fish farm in the Voronezh region. A significant decrease in the concentration of iron, copper, zinc, and manganese in the spring-summer period compared with the autumn-winter period was established. The most dramatic changes in the concentration are typical of copper and zinc. It was shown that the content of heavy metals in pond water exceeded the maximum permissible concentrations for fishery water bodies throughout the year, the smallest exceedance was noted in the spring and summer periods. The data obtained indicate the need for regular monitoring and maintenance of the required level of heavy metals in water bodies to ensure the normal physiological state of hydrobionts.
