Commercial fishing was once a major industry but has been hurt by overfishing. After the war, between 1945 and 1954, the total annual catch increased and reached a maximum of 4,900 tonnes. However, unbalanced fishery led to the drastic decrease of catch in 1955–1963, sometimes to 1,600 tonnes per year. Trawling has been forbidden in Lake Ladoga since 1956 and some other restrictions were imposed. The situation gradually recovered, and in 1971–1990

There are also local roads. The Volga–Baltic Waterway , connecting

During the Last Glacial Maximum , about 17,000 years BP , the lake served likely as a channel that concentrated ice of the Fennoscandian Ice Sheet into an ice stream that fed glacier lobes further east. Deglaciation following

About 85% of the water inflow is due to tributaries, 13% is due to precipitation , and 2% is due to underground waters. Geologically, the Lake Ladoga depression is a graben and syncline structure of Proterozoic age ( Precambrian ). This "Ladoga–Pasha structure", as it

Lake Ladoga was initially part of the Baltic Ice Lake (70–80 m. above present sea level ), a historical freshwater stage of Baltic Sea .
