Abstract
Based on the available data for the 2021/2022 fishing season, the ecological structure and fishing biological parameters of the European anchovy (E. encrasicolus L., 1758), wintering in the coastal waters of Abkhazia, have been analyzed. This paper presents materials that make it possible to analyze the dynamic parameters of the Azov and Black Sea stocks of the European anchovy aggregating off the coast of Abkhazia in the winter season. A comparative analysis of the main biometric parameters has been carried out. For data analysis, well-established ichthyological methods have been used. The available data on the European anchovy (both Black Sea and Azov Sea forms) caught during the investigated period characterize the dynamics of the length-age catch composition and are indicative of its intra-annual fishing patterns. Changes in the population characteristics present in the catch composition as compared with the previous years have been identified. The absolute catch values and their fluctuations are presented by the month. Analysis of the available material has indicated the main dynamic changes that characterize the wintering anchovy population as stable with a tendency for its total biomass development on a moderate level, which is not conducive for increasing the fishing effort in the next 1-2 years.
