The protected area having the particular legal and regulatory status of restricting fishing in its waters has been set up to preserve and rationally use fish stocks within boundaries of the Volga estuarine area. The article presents the analysis of fishing regulations for the Volga-Caspian basin (Astrakhan region) in terms of establishing the boundaries of restricted estuarine area of the Volga. There has been given the dynamics of forming modern borders of the restricted estuarine area of the Volga, according to which, the square of its water area has decreased by 10 times over the last century. It has been noted that the establishment of river and sea boundaries of the restricted estuarine area of the Volga was based on two important principles: the first (permanent) - with reference to fixed objects (settlements, islands, etc.) or to geographical coordinates; the second (dynamic) - to the isobathic curves of depths. The second principle implies to annually revise the river and sea boundaries of the restricted estuarine area of the Volga depending on fluctuations of the Caspian Sea level. In the context of current dynamics of delta development (annual changes in depths of the lower reaches of the delta and avandelta of the Volga river) it has been recommended to use the second principle of the establishment of river and sea boundaries of the restricted estuarine area of the Volga. It has been offered to set annually the boundaries of the restricted estuarine area of the Volga according to the actual boundary of kultuk zone of the Volga delta, and its sea boundaries - according to 1.5 - meter isobathe after ice breaking.
