I like to tell people we eat all the fish we shoot. It's just that 99% of them we turn into corn and tomatoes first.

Seriously, of the rough fish we shoot, gar are my favorite. The Silver and Bighead carp are real good also. Buffalo fish are very similar. Common carp are my least favorite and the most plentiful. They easily make up 80% or better of our take.
The problem is two fold, one is,we couldn't begin to eat all the fish we get. The second is that we are rarely want to stop fishing to clean fish that are not that great in the first place and are time consuming, and by the time we get home they're not really very appetizing looking.
For bowfishing supplies check out F&D Archery, Bowfishing Extreme and Backwater Bowfishing. These guys do a lot to help bowfishing and we try to support them whenever we can.
