Hypoxia tolerance decreases with body size in red drum Sciaenops ocellatus
Mass‐specific oxygen consumption rate, i.e. standard metabolic rate ( R s ) and critical oxygen tension ( P crit ) of red drum Sciaenops ocellatus were measured and scaled over a 2500‐fold range in mass ( M F 0·26–686 g). R s conformed to well established models ( R s = 3·73·91 M F −0·21 r 2 = 0·86)...

| Summary: | Mass‐specific oxygen consumption rate, i.e. standard metabolic rate ( R s ) and critical oxygen tension ( P crit ) of red drum Sciaenops ocellatus were measured and scaled over a 2500‐fold range in mass ( M F 0·26–686 g). R s conformed to well established models ( R s = 3·73·91 M F −0·21 r 2 = 0·86) while P crit increased over the size range ( P crit = 3·15 log 10 M F + 16·19; r 2 = 0·44). This relationship may be ecologically advantageous as it would allow smaller S. ocellatus to better utilize hypoxic zones as habitat and refuge from predators. |
