ABSTRACT. Selection of zooplankton, benthic and plant-dwelling prey by Siberian sturgeon fry was studied. The fish showed distinct selectivity towards large insect larvae, especially plant-dwelling Cloëon dipterum. Small planktonic crustaceans – Eucyclops serrulatus, and very abundant in the pond Bosmina longirostris were avoided.

Key words: STURGEON, FRY, FOOD SELECTIVITY, POND.
