Edit: I should read the whole post before replying more XD
If you're fishing in a small duck pond in a park that isn't connected to a river, I would release them. Somewhere like the Mackenzie or Willamette I wouldn't consider throwing them back alive. The pond I show in the map link I would only do catch and release in since the bass and bluegill are surviving just fine along side the carp somehow. I have been going to the pond daily for 3 years and on a regular basis for over 8 years and haven't noticed any changes in turbidity or population of any of the fish. It's almost perfect [sarcasm]Thanks Beltline[/sarcasm].
As for catfish bait: nightcrawlers, whole chicken livers, or store-bought/homemade stinkbait designed for cats is the only thing I use for them. Never made any home made catfish bait though, just tried my first recipe for carp boilies (in another post.) You should fish them all on the bottom.

AAAnd one last thing, bowfishing in the Long Tom. I started bowfishing just over a month ago now and the only places I've been are the Long Tom and the Amazon Canal (between Fir Butte Road and Fern Ridge, that's also me in the pictures at the top of the homepage
.) Just from the 2 trips that I've taken carp on, I have learned a lot and I haven't even branched out from under the dam much. I'll pm you a bunch of information I've learned to keep the post semi short.
