Figure 3. Metabolic rates (mg O2 kg−1 h−1) correlate positively with behaviour in lake sturgeon Acipenser fulvescens.

Figure 3

Behaviour involved body undulations with tail excursions>90° (min−1). Data were collected from 16:00 h to 23:00 h. Data collection comprised three test groups: control (100% O2sat; 12L∶12D), treatment A (30% O2sat; 12L∶12D), and treatment B (100% O2sat; 24L). Note that symbol colours indicate the three test groups: control (black symbols; long dash line), treatment A (gray symbols; short dash line) and treatment B (white symbols; solid line). The three corresponding linear least squares regressions are highly significant (all P<0.001) and the coefficients of determination (r2) are 0.68, 0.64 and 0.15, respectively.
