Understandable. Even though they're considered traditional edible fish were I live I'm not a huge fan of the taste either.

However, there are two recipe ideas that I think make them quite edible:

1. Fish cakes

(I pre-cook the fillets in a shallow pan with a little water, remove the bones from the cooked fish and then mix it with egg, breadcrumbs, dill, onions, garlic, salt, pepper and various spices... this way, you can get rid of the slightly unpleasant taste quite well. And, very practical for me, you can freeze the finished cakes and then have homemade fast food when you don't feel like cooking ^^)

2. Carp ham

(The fillets are salted in brine and then cold-smoked... supposedly very tasty, and I had planned to try it this spring. Maybe I'll remember to post here about how it turned out).

/edit: Am I right in thinking that the fish is hooked on a treble hook? Are you specifically fishing for carp this way, or was this a bycatch and the bait actually intended for another species?
