Oxygen consumption of five species of fish from south Georgia
The oxygen consumption rates of five species of sub-Antarctic fish, Notothenia rossii Fischer, 1885; Notothenia angustifrons Fischer, 1885; Notothenia nudifrons Lonnberg, 1905; Trematomus hansom Boulenger, 1902; and Harpagifer georgianus Richardson, 1844, have been measured with particular emphasis...
