✦ Synopsis

Abstract

Pressure/volume curves were determined for the bulbus arteriosus and ventral aorta. The curves show a high degree of compliance over the 40 to 60 cm H~2~O pressure range, a range that is similar to ventral aortic blood pressures in trout. Hypoxic, adrenergic and cholinergic treatments all altered the shape of the pressure/volume curves. Arterial blood flow is therefore depulsed in vivo and the extent of depulsation may be regulated.

Atrial natriuretic peptides (ANP) are potent effectors of volume homeostasis in mammals, but their effects on fluid compartments in teleost fish are unknown. In the present study, whole-body blood volume (BV: 51 Cr-red cells), and extracellular fluid volume (ECFV; 58 Co-EDTA space), and 51 Cr-red ce
