sexual maturity in females is reached between 14 and 33 years, most often from 24-26 years; and, 8 to 12 years for males ( but may take up to 22 years );
female lake sturgeon spawn once every 4 to 9 years while males spawn every 2 to 7 years;
spawning occurs on clean, gravel shoals and stream rapids from APRIL - JUNE in preferred water temperatures of 55 - 64 degrees;
female lake sturgeon lay 4,000 to 7,000 eggs per pound of fish;
growth rates are quite variable throughout its range and depend on temperature, food availability, and water quality;
the typical life-span of lake sturgeon is 55 years for males and 80 - 150 years for females.
As a consequence of interrupted spawning cycles, only 10 - 20% of adult lake sturgeon within a population are sexually active and spawn during a given season.
Also czar's camera idea is important because for the money they plan on this project in the Detroit River, it would be a good idea to make sure there not just feeding caveare?( spelling ) to the gobi's and other fish. They can turn the camera off during the mating to give them privacy..lol Also for future projects like this.
