Effects of Addition of Fish Meal to All-Plant Feeds on the Dietary Protein Needs of Channel Catfish in Ponds

Channel catfish were stocked in 27, 1/10-acre ponds at the rate of 3,000 per acre and fed nine commercial-type rations containing three protein percentages and three levels of fish meal for 200 days. Average survival for the experiment was 96.8% and 93% of the fish were over 12 inches in length at harvest. Average yield for treatments ranged from 2,330 to 3,030 Ib/acre and the average for all treatments was 2,638 lb. The results indicated that satisfactory production can be obtained with all-plant rations. The 29%. all-plant protein diet yielded 2,330 Ib/ acre of harvestable size...
