The protein content of game fish chow is 32%. LMB need 40% or higher...preferrably 45%-50% protein. They may go off feed if stocked at low density, fed low protein, at fingerling size, and/or with baitfish present. Look for aquamax line of high protein feeds, as I believe Game Fish Chow is misrepresented. All purina dealers can special order aquamax specialty feeds, just depends on their willingness to work with you.
In addition, those little bass probably weren't feed trained if they are ignoring the feed. Usually at least a few will hit it even if it is low in protein. In the case that they weren't feed-trained, they'll be eating live forage from now on.
