Fig. 1. Rates of oxygen consumption (
O2; 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
O2; N=6 for each species for ammonia excretion).
