The Life of Animals | Lake Sturgeon | The lake sturgeon (Acipenser fulvescens) is a freshwater fish in North America hot, one of about 20 species of sturgeon. The fish uses its elongated nose, like a shovel to mix the sand and silt in the beds of rivers and lakes in the diet. The fish is remarkable in part because of its interference lake size can achieve a total weight exceeding 190 kg (396 pounds) and a length of more than 3 meters (9 feet) along its long life. This species is found in southern Mississippi River basin in Alabama and Mississippi. It occurs in the Great Lakes and east of the St. Lawrence River to the freshwater limit. In the west it joins Lake Winnipeg and the North and South Saskatchewan River.

Anglers must have a valid fishing Minnesota and buy a sturgeon tag to harvest a lake sturgeon. There is also a worrying spearing season on Lake Winnebago in Wisconsin annually. He spent one season in the last 16 days of a remarkable season with a quota, but the season can still claim full 16 days.
