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.

Diagnostic features of bream and white bream scales were investigated. Bream scales were collected from seven sites and white bream ones came from four sites. Both environmental conditions and fish growth rate varied in the chosen sites. The scales taken from the analysed populations varied in shape, localisation of the scale nucleus, number of radii on caudal and oral fields, and by different ratio between their height and width.

Studies were performed on the ovaries of 58 females of white bream, Blicca bjoerkna (L.), from Włocławek Reservoir to determine the character of spawning. Oocyte vitellogenesis in the germ line commenced at the beginning of April, fish reproduction in June-July. The examined females laid eggs in one or two portions.

While studying Myxobolus gill infections of cyprinid fishes, the authors found large, segmented plasmodia in three species: ide (Leuciscus idus), asp (Aspius aspius) and white bream (Blicca bjoerkna). As regards their size and morphology, the spores from these plasmodia corresponded to those of M. dujardini described from chub (Leuciscus cephalus). However, the 18S rDNA sequences of spores from the three cyprinids differed from those of M. dujardini. Based on molecular differences, this paper describes two new species: M. alvarezae sp. nov. from ide and asp, and M. sitjae sp. nov. from white bream. The two new species and M. dujardini had a similar tissue tropism, and infected the multilayered epithelium of the gill filaments. Histological examination of the infected filaments demonstrated that the large plasmodia with multiple buddings were formed from amalgamating small plasmodia. Besides carrying infection in the filamental epithelium, the three above fish species were infected by small intralamellar plasmodia as well. These plasmodia were filled by spores that resembled the roach parasite M. intimus both in morphology and seasonal development. The 18S rDNA sequences of ‘intimus-like’ spores from ide and asp differed only in some base pairs from spores found in the type host roach, and were identified as belonging to M. intimus. The spores found in white bream, however, showed 3.6-5.0% difference in DNA sequence from those of M. intimus; therefore, they have been described as M. eirasianus sp. nov. The aim of this paper was to demonstrate the importance of using molecular methods for separating and identifying morphologically corresponding or closely similar Myxobolus spp.

A total of seven species of parasitic ciliates was recovered from the studied fishes of Dąbie Lake located in the estuary of the Odra River. The common bream harboured the following species: Chilodonella hexasticha, Ch. piscicola, Ichthyophthirius multifiliis, Trichodina modesta, and Trichodinella epizootica. The white bream turned out to be the host for: Ch. piscicola, Capriniana piscium, I. multifiliis, T. modesta, Tripartiella copiosa, and T. epizootica. Three of the above species constitute new records for the parasite fauna of the common bream in Poland, while five-new records for the white bream. Ciliates T. modesta are a new species for Polish parasite fauna. The white bream became a new host for C. piscium. The measurements and photographs of T. modesta and T. copiosa are provided in this paper.
