... (mean ± S.E.) and stroke volume was 0.67±0.24 mlkg −1 when normoxic water flowed over the gills. Ventricular diastolic pressure was zero until atrial contraction filled the ventricle. Ventral aortic pressures were high (mean 12.08±1.15kPa), and blood flow was continuous in the ventral aorta throughout...

... fishes are acclimated to high salinities ( Westenfelder et al . 1988 ; Evans et al . 1989 ). The recent finding that mammalian AP produces vasodilation in the ventral aorta and branchial vasculature of the marine toadfish ( Evans et al . 1989 ) suggests that AP may also play a role in controlling gill...
