I haven't seen any scientific studies of fish food for BG, but intuitively believe the higher the protein the better. This season I switched over to Rangen fish foods for several reasons. 1) I can get higher protein than in any other brand and 2) it is made close by so that it is very fresh and 3) it comes in almost any size you could ask for.
When I went to the plant to pick up two months supply I saw several bags of "Purina Game Fish Chow" which Rangen makes and sells under the Purina brand.
Results so far are terrific. I get 42% protein primarily for the HSB, but the BG thrive on it.
p.s. Cecil makes a terrific point...spend thousands of $ on the pond, hundreds, maybe thousands to stock, and then save a few dollars on a bag on cheap feed?
