Gastric evacuation time.

<p>Values were taken at 24, 48 and 72 hours following forced feeding of <i>P. borchgrevinki</i> with fish white muscle amounting to ∼2% of body mass. The open bar represents the instrumented fish used in cardiorespiratory <i>in vivo</i> experiments (N = 9) and closed bars represent non-instrumented fish (N = 6–7). Values are means (+S.E.M.). * denotes significantly different value (p<0.05) between instrumented and uninstrumented fish at 24 hours postprandial and # denotes significantly different value (p<0.05) from the preceding sampling time in uninstrumented fish.
