Starchasm, if you have a catfish boil, please make enough for me and then feel free to have my share. I don't care for fish, but it sounds like you want people to have fun and eat well. So have at it with my share of catfish! Anytime you want!
Joanie, I think you have the creatures mixed up a bit!
A catfish is a fish. Has "whiskers". And, if you catch them and then fry them up within minutes (as we used to do at our lakehouse), you have never had such wonderful manna from the heavens! My mouth is absolutely watering just typing this!
A crawfish/crawdad is this: http://www.cajuncreations.com/images/CrawfishBowl.gif It belongs to the Crustacea Class and isn't actually a fish. And, you do boil them.
ETA: Starchasm and I responded at the same time.
