mud cat q's

[fish4fish]

I have never been catfishin but i have been reading the posts on here and i was wondering what was the difference between the mud and the channel cats besides the size. are the mud's not good to eat? or is it just that there are so many of them that it takes the thrill out of catching cats? I'm just wondering cus one of these days i will have to make it to utah lake to try for cats.
