Which geographic extremes define the native range of the White Sturgeon in the Pacific basin?
Answer
Aleutian Islands down to California
The White Sturgeon (*A. transmontanus*) holds the distinction of being the largest freshwater fish in North America, and its native distribution is specifically concentrated in the Pacific basin. This range extends geographically from the northernmost reaches near the Aleutian Islands southward along the coastline down to the waters off California. This broad area includes residence in large river systems like the Fraser and Columbia, as well as estuaries and portions of the open ocean, reflecting their anadromous nature.
