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.

We analysed 4 fish species - bream, roach, perch and Gustera blicca bjorkna. It involved the determination of heavy metal content in their tissues, nanol: Cd, Cu, Zn, Pb in muscles, liver and bronchia. The table shows the results including arithmetic mean, SD and extreme values of metal in each tissue. The findings can reflect the contamination degree of the fish in the waters in Wrocław. The comparison of metal levels in time function was made and it is presented in diagrams by regression lines.

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.

Jesienią 1993 r. przeprowadzono badania zawartości rtęci w narządach (tkankach) 7 gatunków ryb odłowionych z rzeki Odry w rejonie Brzegu Dolnego. Określono właściwości fizyczne i chemiczne wody rzeki Odry oraz wzajemne relacje pomiędzy stężeniem rtęci w wodzie, a jej nagromadzeniem w tkankach, zależnie od gatunku ryby i rodzaju narządu. Największe ilości rtęci kumulowały mięśnie badanych ryb, a najmniejsze ilości skrzela.
