To spawn, catfish need a cavity to spawn in. Males guard the eggs that are laid in the cavity. SO, either the catfish dig cavities out of a steep bank somewhere, there are cavities somewhere in the shallower areas of the lake (hollow trees, milk cans, barrels, etc.) or there are areas of dense Chara (I've seen catfish make a "cavity" in Chara that was a couple of feet tall). What kind of catfish are in there?
