They can live in … Males are thought to spawn every 1-2 years, while females appear to spawn every 2-4 years. Spawning occurs during May to July. Unlike with green sturgeon, white sturgeon are not often observed in the ocean and few fish tagged in California have been recaptured in Oregon. Eggs sink and adhere to bottom gravels, hatch in 1-2 weeks, and the fry (young) seek shelter in shallow backwater. They use these to feel and smell food, so putting some stinky bait on the bottom is the way to go when you're sturgeon fishing. The white sturgeon fisheries were (with minor exceptions) closed from 1901 through 1953 due to overfishing. They tend to stick to areas that offer them plenty of food. 4034 Fairview Industrial Drive SE For example, foraging habitat is closely tied to the migratory patterns of their food sources. In 1980, only a handful of adults attempted to spawn in this section of river. Some species live in freshwater habitats. Spawning occurs during May to July. Sturgeons are found throughout the Northern Hemisphere, in both fresh water and salt water. (Observations spanning multiple months or years are excluded from time charts) Migration.
