They bite on powerbait or power eggs. I hooked a 30+ incher with a small piece of powerbait on a size 16 treble 18 inches off the bottom. I've also caught one on a small spoon. They will bite on anything.
Also, if you have never caught a brooder and ate it, in my opinion they taste pretty bad. Other people like eating them, and you might like it too, but just from personal experience I'd throw the fish back, use it as cut bait, or give it to someone else.
Good luck!
