White sturgeon

Easily the largest freshwater fish in North America, the white sturgeon has been known to grow to an incredible length of 20 feet though not in modern times.

Found along the West Coast of North America, and as far north as the Aleutian Islands, sturgeon are ancient fish that have kept the same form for at least 175 million years.

Due to their size, sturgeon are a popular target for fishermen, and there is concern among conservationists that they may be overfished. In fact, some populations are even classified under the Endangered Species Act of 1994.
