Fishing for a Piece of “History”

Lake sturgeon are one of Michigan’s most culturally and historically significant fish species. But many people don’t know much about these living dinosaurs!

The page includes their background, their history, angling information, partnership efforts to manage this species, videos, photos and much more. Visit www.michigan.gov/sturgeon to learn all about this unique fish.

Life History Characteristics of Lake Sturgeon:

Lake sturgeon can grow to weights of up to 200 pounds and lengths of seven feet, with females being longer and heavier than males.
Sexual maturity in females is reached between 21 and 33 years, most often from 24 to 25 years.

Sexual maturity in males is reached between eight to 12 years, but may take up to 22 years.

Sturgeon spawning occurs on clean gravel shoals and stream rapids from April until June in preferred water temperatures of 55 to 64 degrees Fahrenheit.

Female lake sturgeon can deposit 4,000 to 7,000 eggs per pound of fish.
Sturgeon growth rates are quite variable throughout its range and depend on temperature, food availability and water quality.

The typical lifespan of lake sturgeon is 55 years for males and 70 to 100 years for females.
