Fig. 3.

MO₂ of lumpfish before, during and after swim trials at 3, 9 and 15°C. The first two points at each temperature correspond to the routine MO₂ before swimming was initiated. The following points are MO₂ while swimming at increasingly higher speeds until maximum capacity. The final four points at each temperature represents MO₂ over a 2 h period after swimming to exhaustion. Asterisks indicate a significant difference in MO₂ compared to 1 h before swim trials at each respective temperature. N=8. Data are mean±s.e.m.
