Which river basins are specifically noted as primary strongholds hosting significant White Sturgeon populations?
Answer
The Columbia River and its tributaries, and the Fraser River in British Columbia.
While the White Sturgeon is distributed broadly along the eastern Pacific slope, certain major river systems serve as crucial anchors or strongholds for large, concentrated populations. Two river basins are highlighted as primary centers for the species. The first is the extensive Columbia River system, which flows through Washington, Oregon, and Idaho, hosting significant numbers. The second major stronghold is the Fraser River, located in British Columbia, Canada, where the abundance and movements of the sturgeon have been subject to close study due to their significance.
