When I lived in California I fished for them all the time. I prefer them to channel cat for eating.. Don't know of any nearby here in the southerhn Missouri Ozarks. ironically I have recently been searching the internet for some to stock a couple of my ponds. One pond is very small, about 1/8 acre and doesn't have anything in it now. The other is 1-1.25 acre and is stocked with channel cats, some up to 6 pounds, and sunfish (brim?). The problem is that they are not reliable spawners and I get tired of buying new ones every couple years. If I thought i could maintain a self sustaining crop of 10-12+ inch bullheads I would make the switch in a moment.
Actually I have eaten a lot of 8-9 inch ones. In California I could catch the limit of 30 in about an hour, fast as I could bait the hook. Me and my two buddies would catch a limit each and deep fry them with 5-6 pounds of french fries.. They would almost last through a football game on TV. Never filleted them as most were too small. The largest I ever caught was 15 inches and about 2.5 pounds but few were over 12-13 inches.
Bullheads do not have more bones than other catfish. I got to where I could skin and clean them in about a minute each. When cleaning do not cut off the fins. Use skinning pliers to pull them out by the roots.
BTW all fish taste better when taken from cold/clear water. I catch and freeze a lot of channel cats in the winter to tide us over the summer season plankton bloom.
