Pacu or "tambaqui" as they are named in the Amazon, are a delicacy to the natives. The meat is firm but not big flakes. The fish that I bought from the seafood asian store, were awesome. I removed the gill and guts, seasoned it with Lawry's seasoned salt, not too much, made one slice on each side, to the bone, and broiled each side for about 5 minutes, squeeze some lemon over it, and a shots of tequilas...very tasty. If I would cook a fish I raised? that's another issue. I am having a hard time dealing with it...I still have a large mouth bass in my freezer that I raised, but got sick, so I frozed it alive. I can't face the idea of eating it for some reason.
Worth mentioning that the Pacus sold at asian seafood stores are farm raised, so they are probably fed corn meals...
