Fishing pressure for vessels of different power capacity during anchovy trawling in the Azov and Black Seas Basin in 2017
Factors, determining fishing parameters, were studied and analysed; these factors include technical specifications of vessels, engaged in fishing, their equipment and fishing gear, time expenditures for fishing operations, fishing conditions, fishing intensity, trawling time and speed, capacity and synergy of fishing systems, etc. Daily vessel activity reports on anchovy fishing in 2017 were processed, and, based on the obtained data, the most relevant fishing parameters were calculated for vessels of different power capacity: fishing effort, catch per unit effort and fishing pressure. Comparative analysis of five types of vessels, involved in the anchovy trawl fishery in the Azov and Black Seas Basin, was made. The considered types of vessels were the following: medium fishing freezer trawler (10 vessels), small-size fishing trawler (3), receiving and transporting refrigerator (13), TKHS type refrigerated fish carrier (1), refrigerating fishing seiner-trawler, i.e. medium Black Sea seiner, (12). The analysis of fishing pressure parameters for vessels of various types can be applied in fisheries regulation, in case of changes in the resource availability, fish stock assessment, as well as improvement and renovation of fishing systems.
