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.
A bite from a sand flea is most likely to occur at dawn or in the evening and night time hours on the beach or other sandy areas that are near water. Wetlands, swamplands, creeks, and lakebeds are other areas where sand fleas can be found. Sand fleas generally stay close to their breeding ground. They never wander more than 350 feet or about 100 meters from their breeding area. Sand flea swarms produce a high-pitched wine.
