Stomachs were collected in July and August 1981 from April to October from 553 perch, the body length (l.c.) of which ranged from 12.1 to 29.7 cm. The perch were caught in the mid-part of the reservoir, near Nowa Wieś (653rd km of the Vistula). Stomach content analyses showed a high level of plasticity as concerns the diet of perch. The fish fed on organisms which were currently most abundantly available.
