Abstract: Age and growth of brown sole Pleuronectes herzensteini collected from the coastal waters of western Aomori Prefecture from September 1989 to September 1990 were determined from otolith analysis. Observation of the otolith margin verified that annuli (outer margins of the translucent zone) were mainly produced between February and March. This period was associated with the spawning season. Growth of brown sole was expressed by the von Bertalanffy asymptotic growth function as TLt=255.2(1-exp^[-0.463(t-0.267)]) for males and TLt=350.2(1-exp^[-0.308(t-0.300)]) for females, where TLt, is the total length in mm and t is age in years. It was found that the growth rate of brown sole in this study area is very high as compared with the more southern population in the Niigata region. In the northern Japan Sea, there is a tendency that the growth rate in the north is higher in length at comparable ages. It is possible that the growth of brown sole in the northern Japan Sea is closely related with bottom water temperature.
