Data from a three-year radio tagging study of white sturgeon (Acipenser transmontanus) in the Nechako River was consolidated with all other available information on white sturgeon in the Omineca area. The compiled records were compared with the fisheries literature on this species in order to identify the major gaps in our knowledge of the resident sturgeon population and to facilitate a review of the management of the Omineca sturgeon. The information available on Omineca sturgeon showed little discrepancy with sturgeon populations elsewhere, except that this northerly population appears to grow slower and mature later than coastal or southerly populations. The length to weight relationship of white sturgeon suggests that more efficient utilization of the weight potential could be achieved by increasing the minimum size limit of 100 cm by 20 cm to 120 cm. Significant weight gain does not occur until an individual reaches about 120 cm fork length which is at about age 21 for Omineca white sturgeon. The maximu
