Abstract
The object of research in this work is the Caspian vimba Vimba vimba persa (Pallas), one of the commercial fish species of the Caspian Sea. Fish samples taken in the middle part of the Caspian Sea in the autumn period from 2020 to 2023 were analyzed. The work includes studies of Fe concentration in organs and tissues (muscle tissue, gonads, liver, gills, gastrointestinal tract) and food coma of the Caspian vimba Vimba vimba persa (Pallas) aged 2 and 3 years old. It was revealed that Fe accumulation in the liver occurs to a greater extent in the body of the Caspian vimba, and to a lesser extent in muscle tissue. A comparative analysis of the metal concentration was carried out depending on the sex and age of the fish. It was found that females accumulate Fe to a lesser extent than males. The average concentration of Fe in the body of 2-year-old females was 184.11 mg/kg of dry matter, and in 3-year-old females 163.58 mg/kg of dry matter. The average concentration of Fe in the body of males aged 2 years was 203.39 mg/kg of dry matter, and in males aged 3 years 225.92 mg/kg of dry matter. There is also an increase in the concentra-tion of Fe in the body of males upon reaching the age of 3, and a slight decrease in concentration in females. There are sexual differences in the distribution of metal in fish organs (liver, gills, gonads). Of particular interest is the dynamics of metal in the gonads (increases in females, decreases in males). There occurs redistribution of metal in the organs and tissues of fish.
