The amounts of food consumed by silver carp introduced to eutrophic Paproteckie Lake were investigated. The period of food passage, diurnal and periodical food rations, fish increments and feeding coefficients were determined. Annual food consumption was estimated as 8.8 kg, 90% of which was in the three warmest months in the year. Weight increase of fish approximated the average one for the region. Feeding coefficient was about 19, fluctuating between 7.9 and 24.6.
