White Sturgeon spawn many times in their lives. These fish are slow growing and it can take 15-25 years for a female to reach her spawning age, which is a 5 or 6 foot fish. As they age, the females spawn less often, but produce more eggs in each spawning. In the late spring or early summer, they congregate in areas of the river with a fast current, gravel bottom, and a water temperature of 58 °F to 66 °F (14 °C to 19 °C). Upon hatching, the larvae drift downstream with the current until they reach a suitable habitat. About a month after hatching, the Sturgeon will have a full set of fins, rays, and scutes. As small juveniles, they feed on insects, small fish, and small crustaceans. Maturity is reached between 5 and 11 years, depending on the gender of the fish and the temperature of the water.
