In order to take into account the number of amateur anglers when fishing for Asian toothy smelt, small-mouthed smelt and navaga, trips were made to the places of the most intensive fishing. A section of the ice solder in Mordvinov Bay from the village of Okhotsk to Cape Svobodny, as well as the water area of Lake Changeable, was examined.
The impact of amateur fishing on the resources of the prickly crab (Sakhalin residents call it "krabalka") was assessed by the visits of specialists to the ice solder in the area of the village of Lesnoy.
In order to determine the seized volume of biological resources (aquatic biological resources), visual observations were carried out while walking around fishing sites and filming from UAVs. According to the survey data, orthophotographs of the areas of the most intensive amateur fishing have been compiled. With the help of aerial assistants, the scientists assessed the condition of the ice solder, calculated the number of vehicles of winter fishing enthusiasts and obtained data on the number of amateur fishermen on the days of monitoring.
The results of the work carried out will be used to assess the impact of amateur fishing on the stocks of aquatic biological resources of the water bodies of the branch's area of responsibility, as well as in the development of TDES and recommended fishing volumes.
In addition, the materials obtained will make it possible to assess the anthropogenic impact on the WBR in the water bodies of the regions of the Russian Federation of fisheries importance.
