Silver Bass are more comonly known as White bass. Northerners typically refer to them as Silver. They are good to eat. Best if kept ice cold and eaten that day. You can gut them when you catch them and they will be even better. I don't like them when they have been frozen but I do when fresh. They are great for a big fish fry. I am not aware of any closed season, size limit, bag limit etc. Check your local regs. It should be under White Bass. They are farther down the food chain than Walleye. I've never heard of them running Walleye off. They do consume alot of bait however. Give them a try
