Bullheads fed pellets taste quite good even from very warm murky water. I was suprised they did not have any type of off flavor. Meat from bullhead is similar texture as CC and often pinkish at least from yellow bullheads. There is quite a bit of meat on a 12" bullhead especially if you cut out the part just behind the bottom of the gills similar to catfish nuggets.
In a pond situation you may have to 'thin out' their numbers by trapping. They readily enter baited traps. Tuna, dead fish or fish pellets work as baits. If the pond has LMB they will eat a lot of the small 3/4"-2" bullheads.
