Dynamics of the industrial fishing indices of the European anchovy in the Azov and Black Sea Basin in recent years
This paper considers the key aspects of the anchovy industrial fishing in the Azov and Black Sea Basin in 2015–2020. The factors, determining parameters and indices of anchovy fishing, have been analyzed; they include technical specifications and performance characteristics of the vessels engaged in fishing activity, time expenditures for fishing operations, catches per unit effort, fishing areas, the state of fish stocks, and other characteristics. Daily vessel activity reports on the European anchovy fishing for the indicated time range have been processed; the obtained data made it possible to infer the dynamics and trends of industrial fishing indices for the Azov and Black Sea stocks of the European anchovy for this period. The indices of the European anchovy industrial fishing by the Russian Federation in 2015– 2020 have been summarized, both in general and by areas of the Caucasian and Crimean Black Sea coast. The factors, which have predicated the changes in anchovy yield and fishing pressure on the Azov population of the European anchovy, have been investigated. The influxes and the presence of the European anchovy from the Black Sea stock in catches extracted near the Caucasian shore have been recorded, and its fishing operations near the Crimean shore have been characterized. The presented data give evidence that the existing approach of geographical division of the European anchovy into the “Black Sea” and the “Azov Sea” stock units, which is currently laid down the line going through Cape Sarych, does not correspond to the actual distribution of the Black Sea anchovy stock and leads to misrepresentation of fishing statistics. Some means of regulating anchovy industrial fishing and fishing pressure are presented.
