I have no personal experience with the product. The link has some info including "... Bluegill,..., Yellow Perch, and Red Drum are major carnivorous species ". Feeding studies IMO do not agree with these fish species requiring high protein (above 32%). In addition I cant determine from the link what % of the protein is from fish meal which is the best source for predator fish. FM is listed about 4th in line which usually means it is a low %. More info would help.
