Opis:: European perch (Perca fluviatilis) is a widespread species of freshwater fish. The most frequently isolated parasites in this species are endoparasites, such as trematodes, cestodes and nematodes. The purpose of the study was to determine the presence of parasite species found in perch and the correlations between the occurrence of parasites and age in fish from the Lake Góreckie reserve, located in Wielkopolski National Park. Among 139 examined perch, parasites were found in 69,8%. The analysis showed parasite species from the genera Acanthocephalus, Cammallanus, Neoechinorhynchus, Triaenophorus, Proteocephalus and Tetracotylus. The most common parasitosis was taeniasis. The analyses showed that occurrence of parasites correlates with the age of perch. Older fish were more often infected with parasites, especially of the genus Triaenophorus.

Opis:: Background. Parasitological surveys of freshwater fishes rarely include comparisons between two ecologically different bodies of water. Such studies might help to understand processes of establishment of parasite faunas in estuary areas. The results obtained could also provide useful tools for discriminating various fish populations based on the composition of their parasite faunas. The present authors attempted to study such data from Resko Lake-a freshwater coastal lagoon (6 km? surface area), and the adjacent areas of the Baltic Sea. Resko Lake, located 12 km west of the city of Kołobrzeg, is shallow (1.5 m) and is connected to the sea through a small canal (1.3 km long, 30 m wide). Material and methods. The material was collected from April 1969 and July 1970. A total of 159 perch were collected, in this number 104 fish from the lake, 43 from the sea, and 12 from the canal. Results. A total of 32 parasite species were recovered from the fish necropsied. The parasites represented 7 higher taxa: Protozoa (3 species), Cestoda (4), Digenea (13), Nematoda (5), Acanthocephala (3), Mollusca (1), and Crustacea (3). The parasite fauna of perch from the sea was definitely more abundant (31 species) compared to that of the lake (21), and the canal (12 species). Infection parameters of 13 parasite species demonstrated significant differences between the locations studied. The infection level of 6 parasite species was significantly higher in perch from the sea: Bothriocephalus scorpii, Ligula sp., Brachyphallus crenatus, Camallanus truncatus, Hysterothylacium aduncum, and Echinorhynchus gadi. On the other hand, infection levels of 7 other species were higher at the lake: Triaenophorus nodulosus, Bucephalus polymorphus, Azygia lucii, Tylodelphys clavata, Camallanus lacustris, Acanthocephalus lucii, and Achtheres percarum. The infection parameters of the fish from canal were similar to those from the lake. Interesting observations were made on the seasonality of certain parasites of both lake- and Baltic perch. The presently observed differences between parasite faunas of the fish from ecologically different adjacent estuarine locations are certainly caused by diversified environmental conditions that affected the processes of formation of the parasite communities there. Among important factors that could affect compositions of the parasite faunas could have been: availability of the intermediate hosts, exchange of waters (Baltic water influxes to the lake), fish migrations (spawning), and finally the separate identity of the two fish stocks studied.

Opis:: Background. Heavy metals are at present classified among the most important and dangerous water pollutants. Since over 15 years parasites have been used as a bioindicators of water pollution, e.g. using their ability to accumulate heavy metals. Concentration of four elements (Zn, Cd, Ni, Cu) in selected organs of the perch (Perca fluviatilis) and in the tissues of its parasite, plerocercoid of the tapeworm Triaenophorus nodulosus, was analysed. Material and methods. The fish were subject to full helminthological section, resulting in 66 tapeworm larvae isolated from cysts, located in the liver. Plerocecroids, gills, liver and intestine with duodenum were removed and frozen. Content of heavy metals was determined with atomic absorption spectroscopy method. Results. The distribution of the content of Ni, Cd and Zn was similar. In all cases, among all the examined fish organs, the highest mean concentration of the metals was found in the liver, followed by the intestine; it was the lowest in the gills. The mean concentration of the metals in the tapeworm tissues was from 6 to 74 x higher than in the gills, 5−37 x higher than in the intestine and 2.5−28 x higher than in the liver. The concentration of Cu was also the highest in the tapeworm tissues, but its concentration in the fish intestine and liver was nearly the same; it was the lowest in the gills.
