Abstract Weight-specific oxygen consumption of intact bluegill sunfish
was estimated in relation to body weight and temperature by the
sealed jar method. The relationship between body weight and weight-specific oxygen consumption was represented by the equation: Y = aX[superscript b]⁻¹ in which Y is the weight-specific oxygen consumption, expressed
as cc/kg/hr, X the body weight, and a and b-1 are constants
indicating the intercept and slope, respectively, of the curve
of log metabolism versus log body weight. The mean slope of the
regressions was found to be -0.3800 at ten degrees C. and -0.4285
at 20 degrees C.
Tissue QO₂'s for gill, liver and muscle in relation to body
weight were determined at ten and 20 degrees C. The regression
coefficients for gill, liver and muscle at ten degrees were -0.0852,
-0.1505 and -0.3116, and at 20 degrees -0.0799, -0.2070 and 0.1247.
Muscle tissue at 20 degrees C. thus showed an increase in QO₂ with increasing body size. At ten degrees muscle showed metabolic
over- compensation. Metabolic compensation to low temperature
was not seen in gill, liver, or the intact animal.
