Bioindication of the current state of the Kondopoga Bay of Lake Onego in the areas, affected by trout farms, through the use of zooplankton parameters
Lake Onego is one of the biggest European water bodies and a strategic source of drinking water of high quality. In recent decades, trout farming has been intensively developing in the lake. Аt present, 11 trout farms are located in the Kondopoga Bay of Lake Onego. The modern state of the Kondopoga...
