The article is devoted to the study of the commercial and biological characteristics of the wild goldfish in the coastal sea waters of the Terek-Caspian fisheries subdistrict. The features of the formation of wild goldfish stocks under the influence of natural-climatic and anthropogenic factors in the long-term aspect are shown. It has been revealed that in recent years, the stocks of wild goldfish in the coastal part of the Terek-Caspian fisheries subdistrict are stable and range from 1,210 to 1,950 thousand tons having reached the maximum in 2020. Biological indicators of wild goldfish in the coastal part of the Caspian Sea have been stable in recent years and are not subject to significant fluctuations. The high rate of increase in number and commercial stocks, as well as the expansion of the range of wild goldfish in new areas of habitat in the Caspian basin, is probably due to its competitive advantages - the ability to adapt to adverse environmental conditions.
