San Pablo Bay sees surging sturgeon population

A large and unusual concentration of sturgeon in San Pablo Bay has scientists asking questions and local fishermen thrilled. Thousands of the big, bottom-feeding fish are congregating between the Carquinez Strait and the Tiburon peninsula.

Fishermen, who generally spend hours trying to catch a single fish, say this is arguably the best year for white sturgeon in history.

Many believe this year's heavy rainfall is the reason, but, fish and game biologists aren't so sure. They say sturgeon usually move upriver during wet years. They do say active rivers can trigger sturgeon spawning.
