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.
Very prolific fish, sand bass spawn when water temperatures reach 50 to 55 degrees. Female sand bass can produce up to a million eggs and will randomly deposit them over rocks, debris and weeds. Many of the stateâs sand bass will swim upstream to spawn when tributaries are accessible.
