Rudd is one of the most abundant species in the large group of minnow in the Volga-Caspian and Northern-Caspian fishery subareas of the Volga–Caspian fishery basin south. The article contains the data on its catches and usable stocks during ХХ – ХХI centuries. A long term analysis of the rudd catches and the runoff volume during the spring high water showed no substantial connection between these processes due to the rudd’s ecological peculiarities. The dynamics of the rudd catches and the level of the Caspian Sea are connected in inverse ratio. Inverse correlations with high determination coefficients between the rudd catches, the usable stocks, and the sea level were obtained.
