Abstract
The article evaluates the fish resources of the North-West of Russia at the end of the XVIII century. For centuries, fish has significantly supplemented the diet of the population of the North-West of Russia. However, until now, historiography does not have complete data on the fish resources of this territory in previous eras. The study was carried out on the basis of Economic notes to the materials of the General Survey of the end of the XVIII century. It analyzes information about the quantitative and species composition of fish in the territory of St. Petersburg and Novgorod provinces. Databases for individual counties were compiled to assess fish resources. For the first time, a complete processing of the information of the Economic Notes for a particular area was carried out, allowing to take into account all available records on the species and number of fish.
