The annual spawning run of the official state fish, often called the âsand bass,â occurs during the spring and is perhaps best described as a âfish frenzy.â White bass move in large schools to spawn, and anglers who fish at the right time can end up with near constant angling action as well as a stringer full of fish.
About one-half to two-thirds of the eggs are spawned in the Sacramento River and the remainder in the Delta. Female striped bass usually spawn for the first time in their fourth or fifth year, when they are 21 to 25 inches long. Some males mature when they are 2 years old and only about 11 inches long. Most males are mature at age 3 and nearly all females at age 5. Stripers are very prolific.
