life of a Sturgeon!

White sturgeon spawn many times in their lives. 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 rivers with a heavy current, gravel bottom, and a water temperature of 58 °F to 66 °F (14 °C to 19 °C). The fish broadcast spawn in these areas, with males releasing sperm as the outnumbered females release anywhere from 100,000 to a million eggs. The fertilized eggs then sink and adhere to the gravel at the bottom. The eggs are brown in color and will hatch in about a week, depending on water temperature. Female white sturgeon do not spawn every year.
