Abstract: The feeding of burbot Lota lota was studied in the modern conditions of the Kuibyshev Reservoir. With the decrease in the abundance of ruff Gymnocephalus cernuus in the reservoir, gradual establishing of gobies (Gobiidae) within the ruff range began. Recently, gobies form the basis of the of burbot diet. The dominance of alien species in the diet of burbot indicates that this predator may play the role of a regulator of the number of invasive fish species and of a biological ameliorator in waterbody.
