Fig. 7. (A) Integrated tailbeat pressure versus swimming speed for seven cod (Gadus morhua) swimming in a ‘Brett-style’ respirometer at 5°C. IP=19.934x10.611^U, N=84, r²=84.9, P<0.0001; where IP is ‘integrated pressure’ (Pa) and U is swimming speed (m s^–1). (B) Maximum minus minimum pressure or ‘pressure difference’ versus swimming speed for seven cod. PD=44.63x48.22^U, r²=0.87, P<0.0001, N=147, where PD is ‘pressure difference’ (Pa). The double circles represent pressure data calculated from Dubois and Ogilvy (Dubois and Ogilvy, 1978) for swimming bluefish (Pomatomus saltatrix).
