The 32% protein 4% fat is usually considered a lower grade fish food for feeding primarily catfish, tilapia and some forms of koi. Bluegills, HBG and even yellow perch, I have seen eat this lower value fish food. A big however for this type of fish food results in more undigestable food and more fish waste and then generally lower overall water quality as is usually first evidenced by more string green algae being visible and sometimes lower water clarity. .
IMO if growing premium and best growing fish is the goal, then it is best to use a proven high grade fish food with minimal protein content of 40% - 45%. The really important component of high protein fish food is the amount of DIGESTABLE protein that is not mentioned on the bag ingredients label. This is where the user has to trust the producer to provide the best proven ingredients for growing fish. User testimonies and results of those that use the product are good signs of a high quality feed. Those BEST testimonies of premium high quality fish food do not really come from the fish food producers but they come from fish producers who actually grow fish in recurculating water systems. The best fish foods have been tested in the aquaculture recurculating fish grower market.Those fish growers have to daily deal with and manage the amount of fish waste products that the food produces after it has been eaten by the fish.
