| the parasite fauna of brown trout salmo trutta, white fish coregonus lavaretus, and grayling thymallus thymallus from water bodies of north karelia (russia). | the data on parasite fauna of brown trout salmo trutta, whitefish coregonus lavaretus, and grayling thymallus thymallus from lake-river system paanajarvi-olanga (white sea basin) are presented. as lake-river systems on this area remain in natural conditions, without any anthropogenic pressure, the parasite fauna of salmonidae in these water bodies had not been changed and has an archetypal status. | 2004 | 16865973 |
| [morphological variability of proteocephalus percae (müller 1780) parasitizing coregonid fishes]. | morphological variability of proteocephalus percae from native host--perch perca fluviatilis and two species of coregonids (whitefish coregonus lavaretus and arctic cisco c. autumnalis) from fish farms of karelia were studied. parasite groups from 3 host species differed by morphometric parameters. morphological structure of p. percae from native host included three morphs, those numbers were almost equal. parasite groups of whitefish and arctic cisco differed from that of perch in morphological ... | 2015 | 26373190 |
| [specific features of the numbers and structure of the population of proteocephalus longicollis (zeder 1800) (cestoda: proteocephalidea)--a mass parasite of whitefish coregonus lavaretus l. under conditions of technogenic pollution of the water body]. | the numbers, age structure, and morphological variation of the cestode proteocephalus longicollis from whitefish of a natural water body (kamennoe lake) and those of kostomuksha lake polluted with wastes of the mining industry (northern karelia) have been studied. in the polluted water body, a high infestation of whitefish and domination of larval stages in the structure of the parasite population have been established. it is shown that under conditions of pollution, only one of the variations o ... | 2016 | 22988762 |
