خلاصه مقاله:
In this study the cranial nerves development of H. huso are explained from ۱ to ۵۴-days-old (۱, ۳, ۶, ۱۵, ۲۱ and ۵۴ days). Despite all the researches on fish brain, there are no study on nerves evolution on H. huso during their larvae life. For this research ۴۰ samples of larvae H. husowere obtained (from each age, about six samples were selected). The specimens were maintained in fiberglass tank, then histological samples were taken from tissues and stained with hematoxylin and eosin for general histological studies using light microscope. According to the results, on ۱ and ۳-days-old, no nerve was observed. The terminal nerve and their dendrites were observed around the nasal cavity and the axons projected to different areas in forebrain especially around olfactory bulb diffusely, on ۶-day-old fish. Also, olfactory, optic, oculomotor, trochlear, trigeminal, lateral line and vagus nerves were detected on ۶-day-old fish, however two parts of lateral line nerve were separated on ۵۴-day-old. Three nerves, profundus, facial and octaval were observed on ۵۴-day-old, however, up to this age, epiphysial nerve was not observed.
