cleaning catfish - the skinning part

[alcom]

Does anyone have experience cleaning catfish? I'm thinking of trying for channel cats and don't know if they need to be skinned.

Here's what I do for bullheads:
* Snip off the fins/spines with wire cutters
* Slit the skin down the back from head to tail
* Cut through the backbone (just) but not the entrails
* One thumb goes into the body cavity and grabs the backbone
* The other hand grabs the head
* Pull, and the entrails come out as the skin is peeled off

I imagine it would be hard to do that with a channel cat.
