title: [Receptor cells of different types and quantitative relations between them in the organ of smell of larval and adult specimens of acipenserid fishes].
abstract: Three types of olfactory cells: rod-like and cone-like (flagellar olfactory cells) and filamentous (microvillar olfactory cells), which have been described previously in adult Acipenseridae were found in the olfactory organ of the ten-days larval sturgeons (Acipenser güldenstädti), sevrugas (Acipenser stellatus) and sterlets (Acipenser ruthenus). The flagellar olfactory receptors appeared to predominate in both ten-days larvae and adults of the anadromous sturgeons and sevrugas, while the microvillar olfactory receptors predominate in freshwater sterlets in ten-days larvae as well in adults. The facts obtained confirm the idea that the rod-like, cone-like and filamentous olfactory cells are independent types of olfactory receptors. The different ratios of these cells in the olfactory organs of anadromous and fresh-water Acipenseridae may be a result of their ecological adaptations.
