Fig. 1. Whole animal metabolic rate. (A) Estimates of metabolic rate as calculated
by O2 consumption (mg O2 h–1) at
21°C. BG, bluegill sunfish: y=0.93x–0.72,
N=10, R2=0.81; PS, pumpkinseed sunfish:
y=0.87x–0.50, N=18,
R2=0.62; LM, largemouth bass:
y=0.94x–0.54, N=14,
R2=0.93; SM, smallmouth bass:
y=0.96x–0.51, N=9,
R2=0.97. (B) Log–log relationships were used to
predict metabolic rate (mg O2 kg–1
h–1) of a standardized 15 g, 50 g and 150 g fish (±95%
confidence interval).
