Feeding catfish high priced food reaches a point
of diminishing returns. I fed 42% protein Aquamax
for a while, but changed to the 32% pellets. The
Aquamax sold for around $24/50lbs and I can get
feed mill produced 32% for $10/50lbs. And, the
catfish in my ponds can go thru a 50lb bag
in a week in each pond. That can add up to a bit of money. The fish start to get so large, that
they are eating more food than the four legged livestock. And, you can eat only so much catfish.
