Cardiovascular effects of trout CNP (tCNP) infusion (10 nmol kg–1 h–1, administered after dotted line) on cardiovascular parameters in unanesthetized trout. The gray line is +1 s.e.m. (N=8). fH, heart rate (beats min–1); OC, cardiac output (ml min–1 kg–1); PVA, PDA and PVEN, ventral aortic pressure, dorsal aortic pressure and central venous pressure, respectively (mmHg); RG and RS, gill resistance and systemic resistance, respectively (mmHg min–1 kg–1 body weight ml–1); VS, stroke volume (ml beat–1).
