Cardiorespiratory status before and after feeding.

<p><i>P. borchgrevinki</i> were force fed with fish white muscle amounting to ∼2% of body mass. Open bars are unfed fish (N = 9–14) and closed bars are 24 h after feeding (N = 5–8). The variables are cardiac output (Q), gastrointestinal blood flow (q_gast), oxygen consumption (MO₂), stroke volume (SV), heart rate (<i>f</i>_H), dorsal aortic blood pressure (P_da), systemic vascular resistance (R_sys) and gastrointestinal vascular resistance (R_gast). Values are means (+S.E.M.) and * denotes significantly different value (p<0.05) from the unfed control.
