Tadajewska M., 1993. Food of bream, Abramis brama (L.), and white bream, Blicca bjoerkna (L.), in Zegrzyński dam reservoir. Acta Ichthyol. Piscat. 23 (2): 77-101.
Studies were carried out in 1987 and 1988 on the content of food tracts of 636 bream and 537 white bream from Zegrzyński Dam Reservoir. Samples were collected from three stations: Wierzbica, Bug and Zegrze. The fish fed mainly on Chironomidae (larvae and pupae) and Mollusca. Chironomus sp. and Glyptotendipes sp. were the two most frequently consumed genera from among the Chironomidae larvae.
