Figures
- Fig. 1.
Rates of oxygen consumption (ṀO2; A) and net ammonia excretion (B) prior to and following exhaustive exercise in shortnose and Atlantic sturgeon. Asterisks denote significant differences (P<0.05) from resting values (C), and a dagger indicates a significant difference (P<0.05) between shortnose and Atlantic sturgeon at a particular sampling time. Negative values indicate net ammonia losses from the fish (net efflux). Values are means ± s.e.m. (N=8, for each species for ṀO2; N=6 for each species for ammonia excretion).
- Fig. 2.
Phosphocreatine (PCr; A) and glycogen (B) concentrations (μmol g–1) in the muscle of shortnose sturgeon at rest (C) and following 0, 1, 2 and 6 h of recovery after exhaustive exercise. An asterisk denotes a significant difference (P<0.05) from the resting value. Values are means + s.e.m. (N=7–11).
- Fig. 3.
Lactate (A), pyruvate (B) and glucose (C) concentrations (μmol g–1) in the muscle of shortnose sturgeon at rest (C) and following 0, 1, 2 and 6 h of recovery after exhaustive exercise. An asterisk denotes a significant difference (P<0.05) from resting values. Values are means + s.e.m. (N=7–11).
- Fig. 4.
Lactate concentration (mmol l–1) (A) and osmolality (mosmol kg–1) (B) in the plasma of shortnose sturgeon at rest (C) and following 0, 2 and 6 h of recovery after exhaustive exercise. An asterisk denotes a significant difference (P<0.05) from the resting value. Values are means + s.e.m. (N=5–7).
