Abstract—General ideas about the trophicity of fresh waters, trophic scales, and trophic indices are consi-dered. An assessment of the trophic status of the Volga reservoirs is provided. Changes in the abiotic characteristics of the reservoirs and production–destruction indicators in waters of different trophies are considered.

Keywords: Volga reservoirs, trophic status, production characteristics, abiotic characteristics, trophic gradient
