... labrax ) at rest and while swimming at 1 and 2 BL s -1 . MCFP, an index of venous capacitance and the upstream venous pressure driving the return of venous blood to the heart, was measured as the plateau in P cv during ventral aortic occlusion. Compared with resting values, swimming at 1 and 2 BL s -1...

... of venous capacitance vessels were assessed, immediately following either occlusion, by measuring mean circulatory filling pressure (MCFP). Arterial responses were evaluated as the change in dorsal aortic blood pressure( P da ) before and after pre-branchial occlusion. In untreated fish pre-branchial...
