Abstract: ABSTRACT. The presence of bacteria and parasites on the gills of pike and tench from Oœwin Lake in the Seven Islands Reserve was investigated. Parallel bacteriological analyses of the water were done. The materials were sampled in May-June, July, October 1999, six years after the water level had been increased. The bacteriological and parasitological results both indicate that this body of water is eutrophic. The increase in the incidence of infection with Ergasilus sieboldi and an increase in the number of heterotrophic bacteria were observed simultaneously on the gills. Based on the parasitological and microbiological analysis of gills, the prognosis for the health of pike is unfavorable.
