The female sturgeon spawns once every four to nine years. Spawning occurs from April to June on the clean gravel shoals and stream rapids. They require a moderate water temperature, usually between 55-64 F (12.7-337.7 C). The average litter size is 4000-7000 eggs, followed by an incubation period of eight to 14 days.
