We eat carp in eastern Europe, and if I'm not mistaken, carp is the most commonly farm-raised fish world wide. Their meat is very good, but it is bony. The meat is flaky and falls away from the bones. In Europe, carp is the premier game fish that everyone wants to hook into. They are very strong and put up a fight, sometimes even ruining your reel and breaking your rod. Carp fishing is quickly gaining popularity in the US, with numerous websites and tournaments organized.
See carp.com and carp.net for info. I never ate carp over 3.5kg (about 7lbs, 3yrs old), so I don't know what the giants on these websites would taste like. I have to say that in Czech Republic, they get fed corn and about a month before the sale they are kept in tanks with clean water. But the ones you can get in Houson in Fiesta or Hong Kong market are just as good.
I forgot to add - don't eat grass carp aka White Amur. I never tried it, but I hear that their meat is very oily.
