Аннотация: Представлены результаты паразитологических исследований развивающейся икры, личинок и мальков горбуши в искусственных и естественных условиях воспроизводства. Впервые выделено пять видов простейших паразитов: Ichthyobodo necator, Chilodonella piscicola, Tetrahymena pyriformis, Entamoeba sp., Vorticella sp., а также грибы рода Saprolegnia. Даны количественные показатели заражённости икры простейшими и грибами. Выявлены патологические изменения, вызванные данными возбудителями. Отмечена способность паразитов и грибов переживать экстремальные условия./Results of parasitological researches of egg, larvae and juvenile pink salmon of artificial and natural reproduction have been represented. For the first time five species of Protozoa parasites incleding Ichthyobodo necator, Chilodonella piscicola, Tetrahymena pyriformis, Entamoeba sp. and Vorticella sp. and Saprolegnia fungus have been found. Quantitative characteristics of the rate of egg infection with protozoa and fungus have been provided. Pathological changes caused by the pathogens mentioned above have figured out. The ability of parasites and fungus to survive in extreme conditions has been admitted.

Аннотация: Features of spatial and vertical distributions of two species of anadromous parasitic lampreys, Arctic lamprey Lethenteron camtschaticum and Pacific lamprey Enthosphenus tridentatus, in the North Pacific Ocean are considered in a comparative perspective. It is shown that the first species is most abundant in the northwestern Pacific (Sea of Japan and Sea of Okhotsk), while second species - in the northeastern Pacific (west coast of USA and Canada). Both species reach high abundance in the Bering Sea, however prefer different biotopes. Arctic lamprey inhabits mostly upper 100-m layer, while Pacific lamprey occupies water column with depths less than 200 m and near-bottom layers shallower 500 m. Based on the features of spatial and vertical distributions, it might be assumed that the hosts of the former species are mainly Pacific salmons Oncrorhynchus spp., while those of the latter species - various demersal fishes such as walleye pollock Theragra chalcogramma, Pacific cod Gadus macrocephalus, Greenland halibut Reinhardtius hippoglossoides, etc.
