Low-intensity production of Channel Catfish Ictalurus punctatus is characterized by low stocking rates, low installed aeration capacity, and no automated dissolved oxygen monitoring. Two studies conducted in nine 0.25-acre ponds quantified production characteristics of stocker Channel Catfish stocked for low-intensity food-fish production in single- or multiple-batch culture. In the multiple-batch study, 0.5-lb stockers (carryover fish) were stocked at 4,500 fish/acre and 0.044-lb fingerlings at 6,000 fish/acre. Stockers were grown to mean individual weights of 1.25, 1.75, or 2.25 lb. In the single-batch study, 0.5-lb stockers were stocked at 3,500, 4,500, and 5,500 fish/acre. All fish were fed a feed containing …

Catfish farmers increasingly are producing fish larger than the traditional size of 0.45-0.57 kg/fish in order to meet processing plant requirements for larger fish. Production of larger channel catfish (Ictalurus punctatus) in multiple-batch culture has been investigated in a few studies, but the impact of understocked fingerlings on growth of carry-over fish is unknown. The present study was conducted to quantify growth, feed conversion ratio, net daily yield, and net and total yield of stocker channel catfish grown in single-batch, one-season culture to mean individual weights of 0.60, 0.72, 0.91, or 1.17 kg/fish. Channel catfish (mean weight = …
