I have used left-over pike for fish tacos. It was pike wrapped in foil w/ lemone. butter, garlic, salt & pepper. Had some left-over so the next day we made fish tacos w/ it. I thought it was real good, but I love fish tacos. What I do w/ halibut for tacos is rub it with olive oil, salt & pepper, lemon or lime juice, and chili powder. Makes great taco's and I bet it would work real good for pike too. Just my $.02
