If growth of your fish is one of your main goals then a fish food with higher protein comprised with a lot of fish meal is your best overall option. Note the AMax MVP (multi-varible particle) fish food has 43% protein as mostly fish meal is a very good choice if you have several sizes of fish that you want to grow well. 43% protein is 7% more protein per pellet than 36% protein. The type of protein and digestibility of the protein is also very important (see ewests post).

Note the promo for Sportsmen's Choice does not mention fish meal as an ingredient.

If you really care about the best growth of your fish take the time and read through and learn from ewest's excellent fish food nutrition post above.
It would be very educational to see a fish feeding study that measures the amount of waste (manure) produced by several of these fish foods. Would SDSU be capable of doing a study like this and funded by donations of Pond Boss Members?
