The data on ichthyological studies in the eastern part of the Taganrog Bay and the mouth of the Don River in the period from January to July 2025 are presented. During this period, 43 fish species belonging to 13 families were caught. Such previously common species as sabrefish, vimba, shemaya began to be encountered individually or their catches decreased significantly. The most common catch in terms of the number of species included 21 fish species (common carp, silver crucian carp, kutum, white bream, mullet, rudd, pike perch, roach, needlefish, etc.). Our daily monitoring confirms that in addition to sturgeon, the Azov semi-anadromous populations of pike perch, bream and sabrefish are on the verge of extinction. The number of other valuable commercial fish - carp, roach, vimba - has also sharply decreased.
