The Relation of Standard Metabolic Rate to Water Temperature and Body Weight of Schlegels Black Rockfish ( Sebastodes Fuscescens)

摘要

Standard metabolic rates of Schlegels black rockfish with different body weights are determined in laboratory by using the flow-through respirometer at 11.2℃, 14.7℃, 18.0℃ and 23.6℃. The results indicate that the standard metabolic rates increase with the increase of body weight at different temperatures. Relationship between them could be described as Rs = a lnW~b . The mean of standard metabolic rate is significantly different among groups, but the b values are not. The standard metabolic rates of amended standard body weights decrease with the increase of temperature, and the mean of standard metabolic rate is also significantly different among groups when the standard body weights are 48.6 g, 147.9 g, and 243.1 g. Relationship between them could be described as Rsw = m e~(-b/T) . The relations of standard metabolic rate ( Rs) or relative metabolic rate ( Rs) to body weight and temperature yield the following equations: Rs = 1.160 W~(0.752) e~(-9.494/T) and Rs′= 1.160 W~(0.254) e~(-9494/T).
