BC, Bluegill generally spawn from Mid May to Mid October, but cold weather can change it up a bit. In your area, you should get at least 3 or 4 spawns, up to 10,000 eggs per fish. The nests will turn over from fish to fish as they become ready to spawn. Once occupied, they become VERY agressive to anything entering the area, fun stuff to watch. I've seen established "communities" where the same fish actually have their home. If your fish are competing for a spawning bed, that's a good sign, that means you have a LOT of bgill and they need to take turns. Most often, the large adults occupy the deeper beds and compete to keep them. Fun stuff...and you can even hand feed them if you're patient enough.
