The article reports a significant increase in the catch of wild oysters in the Far Eastern fisheries basin in Russia during the first half of 2021. The wild oyster catch doubled, reaching 185 tons, and the cultivated oyster volume increased by 12% compared to the previous year, totaling 4.4 thousand tons. This growth is attributed to a trend of import substitution and regulatory improvements, with mariculture enterprises primarily located in the Far East, Crimea, and Krasnodar Territory contributing to the domestically supply. Scientists confirm that the oyster stocks are currently stable.
