Fig. 4. (A) The gross cost of transport (GCOT, broken lines) and net cost of transport COT_net, solid lines) estimates for bonito swimming at 18°C (blue) and 24°C (red). [Note: 24°C values are estimated from 18°C values, based on a Q₁₀ of 2.0 (see text).] (B) Comparison of the GCOT (broken lines) and COT_net (solid lines) values predicted for the bonito (red) at 24°C with estimates for similar sized yellowfin tuna (black) at 24±1°C (Dewar and Graham, 1994a).
