Low density, autumn stocking in combination with temperature-based feeding substantially increased channel catfish fingerling weight by the subesequent spring. The advanced spring fingerling size (0.19-lb) allowed production of a 1.45-lb food-fish (1343 fish/acre) in 180 days.ow density, autumn stocking in combination with temperature-based feeding substantially increased channel catfish fingerling weight by the subesequent spring.
