from mid-March through 11 April. Daily feed consumption aver-aged 68.6 ± 9.5 g/m3 and 69.9 ± 9.5 g/m3 in the low and high solids treatments, respectively, during the last 10 days of feeding. This feed rate typically is observed from late-June through mid-Julyin the BFT tanks stocked with channel catfish at 12 fish/m2. Total feed consumption did not differ significantly between treatments(P = 0.410), averaged (±SE) 0.95 ± 0.01 kg/m3 and 0.96 ± 0.00 kg/m3 for the low and high solids treatments, respectively, and does notexpla in the difference between low solids initial and final weights.This difference more likely was the result of sampling error since initial weight was obtained by weighing individually all fish in each tank, whereas final weight was obtained by weighing a random sample of 25% of fish in each tank.
