Fishing intensity in the Russian part of Vistula lagoon
2020
Shibaev, S.V.
The article considers the results of a study of the intensity of fishing in the Russian part of the Vistula Lagoon (Kaliningrad Bay). There are several available sources of information about the fishery, which are typical for inland waters. These include data of fishing licenses (permissions), 5-day reports by fishermen and logbooks. The first allows you to determine the composition of fishing companies, fleet and the list of fishing gears, the second gives information about total catch; the third provides data about daily catch, types and number of gear, location of the fishery and landing. Reports and logbooks have low reliability in relation to volume of catch, however, data about type, number of fishing gears seem to be more correct. Using a combination of data from all sources, the magnitude of the fishing effort, the temporal dynamics of fishing intensity, the species composition of catches for the main types of gears. It is shown that the existing fishing effort does not exceed the production capabilities of aquatic bioresources. The maximum intensity of fishing was calculated to reach total usage of quotas. It is proposed to restore in the freshwater a new system of fishery monitoring, similar to the one that existed before 2004, and to introduce approaches to regulating fisheries through the regulation of fishing effort, which will ensure greater efficiency of control and management of aquatic bioresources
