Five years of study of white sturgeon in the Fraser River drainage has provided information to help meet the original program objectives that were developed in 1995. Generally, the results showed that there are at least five Stock Groups of white sturgeon in the Fraser River drainage. Four stocks reside in the Fraser River mainstem with a fifth stock existing in the Nechako River drainage. All white sturgeon stocks were determined to be genetically distinct; stocks in the lower Fraser River had a higher genetic diversity than stocks in the upper Fraser or Nechako Rivers. Further, white sturgeon that occupy the area downstream of Hope appear to be part of a stock complex rather than a single stock. Information on population structure, size, and density; movements; and spawning of these stocks is provided in this report along with conservation recommendations.
