As the water begins to cool when air temperature drops in the fall, fish may require less protein and fat in their diets. Feed Kenny's Bargain Bits formulated with 32% protein derived from easily-assimilated premium plant and ruminant-free proteins along with menhaden fish meal. Kenny's Bargain Bits is considered a year-round maintenance diet that can be fed from Spring to Fall.   Discontinue feeding koi and other pond fish in the fall when water temperature reaches 50 degrees F.
