Channel Cats are cavity spawners. They like cavities with one way in and one way out. Anything can be used as long as its nothing harmful to the fish. crocks, flower pots, barrels and drums. If needed cut one hole big enough for adult cc's to swim through and sink it. They are more likey to spawn with cavities. And they probably wont without them. Also the success rate may be limited with the BG and LMB as they will prey upon the eggs, fry and fingerlings.
