Specialists from the Volgograd branch of VNIRO continue to monitor the wintering conditions of fish in the reservoirs of the Volga-Akhtuba floodplain

 

During the research, water samples were taken at the monitoring sites of the Volga-Akhtuba floodplain for analysis of hydrogen sulfide content and determination of acute toxicity. Key hydrochemical and physical parameters were measured at the site: pH level, water temperature, dissolved oxygen concentration, depth of water bodies, as well as the thickness of ice and snow cover.

 

Preliminary results of the conducted research indicate favorable wintering conditions for aquatic biological resources. The absence of acute toxicity and stable hydrochemical indicators confirm that the ecological state of water bodies remains within the norm: these factors contribute to the successful wintering of fish.
