During the expedition, the scientists focused on a comprehensive assessment of aquatic biological resources.: They not only analyzed the structure of fish populations, but also studied their biological parameters in detail.
The key stage of the work was the analysis of catches of bottom floating nets — the specialists recorded the species and quantitative composition of the prey, as well as performed dimensional and mass measurements of each caught individual. At the same time, hydrobiological samples were taken: this made it possible to assess the condition of the feed base of the watercourse and obtain a more complete picture of the ecosystem of the river.
The collected data will become a reliable basis for an objective assessment of the current abundance of aquatic biological resources. Based on the received materials, forecast calculations will be prepared that will help justify the recommended catch volumes in the study area and ensure the rational use of fish stocks.
