This study links the anatomy of the peripheral olfactory organ in the bottom-dwelling round goby (Neogobius melanostomus) with behavioural responses to putative pheromones and conspecific extracts. The spatial organization of the nasal cavity was examined using impression material injection, immunocytochemistry, and transmission electron microscopy. The peripheral olfactory organ had a compact structure with an olfactory chamber that contained a single longitudinal lamella. Prominent dorsocaudal lachrymal and ethmoid accessory nasal sacs were situated ventrocaudal to the chamber. The location of the olfactory mucosa within the olfactory chamber is novel for teleost fish, as it extends dorsally beyond the ventral surface. Microvillar and ciliated olfactory sensory neurons were identified by transmission electron microscopy. Galphaolf-immunoreactive ciliated olfactory sensory neurons and Galpha0-immunoreactive microvillar olfactory sensory neurons were located throughout the olfactory epithelium. Galpha0-immunoreactive crypt cells were also found throughout the olfactory epithelium of some specimens. The effect of female conspecific urogenital extracts on ventilation was studied on male round gobies. (Abstract shortened by UMI.)Dept. of Biological Sciences.
