Help with a answering this riddle about fishing?

On my recent trip to Michigan, I caught three types of fish on one fishing trip. I caught four perch, one b, and five trout. I let the b go, so I had nine fish then to bring home. On fishing trip number two, I let six of the previous fish go. I was supposed to bring home five fish, however, to my three-person household. What singular food item did I buy to replace the missing fish?
