Ventricular and Arterial Dynamics of Anaesthetised and Swimming Tuna
Cardiovascular dynamics of tuna have been investigated by recording blood pressures and flows in the central circulation of both anaesthetised and swimming individuals. In anaesthetised fish (N=5), heart rate averaged 1 1 2 S l beats min-l (mean 2 s.E.) and stroke volume was 0.67M.24mlkg-' when normoxic water flowed over the gills. Ventricular diastolic pressure was zero until atrial contractio...
متن کاملMoving with the beat: heart rate and visceral temperature of free-swimming and feeding bluefin tuna.
Owing to the inherent difficulties of studying bluefin tuna, nothing is known of the cardiovascular function of free-swimming fish. Here, we surgically implanted newly designed data loggers into the visceral cavity of juvenile southern bluefin tuna (Thunnus maccoyii) to measure changes in the heart rate (fH) and visceral temperature (TV) during a two-week feeding regime in sea pens at Port Linc...
متن کاملStudies of Tropical Tuna Swimming Performance in a Large Water Tunnel - Kinematics
Yellowfin tuna (Thunnus albacares) swimming kinematics was studied in a large water tunnel at controlled swimming velocities (U). Quantified kinematic variables included the tail-beat frequency, stride length (l), caudal amplitude, yaw, the propulsive wavelength, the speed of the propulsive wave (C) and the sweepback angle of the pectoral fins. In general, all variables, except the propulsive w...
متن کاملStudies of Tropical Tuna Swimming Performance in a Large Water Tunnel - Thermoregulation
The body temperatures (Tb) of nine yellowfin tuna (Thunnus albacares) were monitored while fish swam in a large water tunnel at controlled velocities (U) and ambient temperatures (Ta). Monitoring Tb during step changes in Ta at constant U permitted estimation of the thermal rate coefficient (k), an index of heat transfer. In the yellowfin, k is dependent on both Ta and the direction of the ther...
