Abstract—Specific features of the morphohistochemical and ultrastructural organization of the secretory sys-
tem of olfactory organs in marine fish from the Pacific region were studied. Multicellular alveolar and tubular
glands were revealed in the olfactory epithelium of Pleurogrammus azonus, Myoxocephalus yaok, Enophrys
diceraus, Alcichthys elongatus, Gymnocanthus pistilliger, Hemilepidotus gilberti, Hemitripterus villosus,
Podothecus veternus, Liparis dubius, Clupea pallasi, as well as in salmonids (Oncorhynchus nerka, O. keta,
O.gorbuscha, O. masou, O. kisutch, O. tschawytscha) and in tetraodontids (Takifugu rubripes). The morpho-
functional characteristic of the described glands is close to the Bowman’s glands of land animals. The structure,
localization, and density of location of olfactory glands are determined by specific features of the ecology of
the species. These structures are most numerous in bottom and near-bottom representatives of marine ichthyo-
fauna.
