LOL, what do you think "whole fish" turns into once they process it for fish food? It's ALL fish meal... Some fish meals are just better quality. Sounds like you have bought in to some clever fish food marketing.
OP, here's the basic ingredients from the pellets I feed my fish:
Typical Ingredients: Whole Antarctic Krill Meal, Whole Herring Meal, Wheat Flour, Whole Squid Meal, Algae Meal, Soybean Isolate, Beta Carotene, Spirulina, Garlic, Vegetable and Fruit Extract (Spinach, Broccoli, Red Pepper, Zucchini, Tomato, Pea, Red and Green Cabbage, Apple, Apricot, Mango, Kiwi, Papaya, Peach, Pear), Vitamins.
Not to get too involved in the conversation, but you want to look for something along those lines.
