    Parasitological investigation were performed in Dgał Wielki, occurrence T. pediculus Ehrenberg 1838 on the roach gills were recorded. On the 277 examined roach in 9 roach specimens T. pediculus were found. Prevalence of roach infection was 3.25%, mean intensity 3.5 and abundance 0,11 parasite per number of fish examined. T. pediculus were found on fish in May and June.

    Opis:
    A study was carried out in a shallow, eutrophic Oświn Lake, within Seven Islands Reserve (north-eastern Poland), in order to determine the infection of fish with monogeneans as sensitive indicators of water quality. This paper presents comparative analysis of the occurrence of Monogenea in fishes from two, distinctly separated pools of the lake, differing in environmental conditions. The impact of fish size and sampling season on the infection parameters was also analyzed. Material and methods. In 1998 and 1999, a total of 1091 fish representing 8 dominant species were examined. Samples were collected four times a year (in May, July, August, and October) simultaneously from the eastern and western parts of the lake. Results. 16 species of Monogenea (and some unidentified specimeus) occurred in the fish examined, most of them from the Dactylogyridae family: Dactylogyrus sphyrna, D. auriculatus, D. intermedius, D. anchoratus, D. falcatus, D. tincae, D. wunderi, D. zandti, D. difformis, D. nanus, D. distinguendus, D. crucifer, D. caballeroi. Furthermore, Tetraonchus monenteron (Tetraonchidae), Gyrodactylus elegans (Gyrodactylidae), and Paradiplozoon megan (Diplozoidae) were detected. Monogenea occurred abundantly on the gills of pike, roach, rudd, white bream, carp bream and crucian carp, but rather sporadically in tench and perch. The highest species variety and diversity of monogenean guilds were detected in carp bream and roach. It was proved that D. crucifer and D. difformis were significantly more abundant in the western pool compared to the eastern one. Infection of fish with Dactylogyridae was season-dependent, contrary to the infection of pike with T. monenteron. Intensity of infection of white bream with D. sphyrna and roach with D. crucifer increased with fish body length; such a relationship did not appear for the other monogeneans and their hosts. Conclusion. Presence of common Monogenea in the fish examined, lack of rare species, poor diversity of monogenean guilds and relatively low infection rate could be connected with the low stability of the lake environment. Location-dependent occurrence of D. crucifer and D. difformis indicated that the exchange between fish groups from the eastern and western parts of the lake is limited.

    Opis:
    The objective of the experiment was to compare the growth rate in two groups of Siberian sturgeon fry, one of which was infested with metacercariae of Diplostomum, the infestation degree was from 1 to 160/fish. The fish fed on natural as well as artificial food; the latter was given at the rate sufficient to cover 50% of the fish requirements. The average initial body weight in the control group was 16.8 ± 1.9g, and in the group with Diplostomum - 28.4 ± 3.6 g. During the period of favorable temperatures, viz. for about 90 days, the fry was showed satisfactory growth, but the growth rate becaine inhibited as the temperatures decreased to below 12°C, so that throughout the wintering period the fish weight decreased by some 10%. Fish from the control group showed a higher growth rate than the infested ones, and by the end of the experiment the controls weighted 7.5% more than the infested group in spite of their lower initial weight.
