Substrate utilization during graded aerobic exercise in rainbow trout.
A biochemical approach was employed to examine the oxidative utilization of carbohydrate and lipid in red muscle of rainbow trout (Oncorhynchus mykiss) during sustained swimming at 30 and 60% of their critical swimming speed (U(crit); for 2, 15 and 240 min) and during non-sustainable swimming at 90% U(crit) (for 2, 15 and 45 min). Measurements included pyruvate dehydrogenase (PDH) activity, cre...
متن کاملCO2 transport and excretion in rainbow trout (Oncorhynchus mykiss) during graded sustained exercise.
A quantitative analysis of CO2 transport and excretion was conducted in seawater acclimated rainbow trout (Oncorhynchus mykiss) swimming at different sustained swimming velocities. CO2 excretion increased linearly with cardiac output during exercise but arterial P(CO2) (Pa(CO2)) and total CO2 levels also increased indicating a diffusion limitation to CO2 excretion. The elevated Pa(CO2) was not ...
متن کاملThe interaction between O2 and CO2 exchange in rainbow trout during graded sustained exercise.
A quantitative analysis of O2 and CO2 transport was conducted in resting and exercising rainbow trout, and these data were used to quantify the magnitude of coupling between O2 and CO2 exchange, in vivo. The release of Bohr protons during haemoglobin-oxygenation was non-linear over the Hb-O2 equilibrium curve used in trout subjected to different levels of sustained exercise. At low swimming spe...
متن کاملGenetic parameters of growth in rainbow trout, Oncorhynchus mykiss, at early rearing stage
The heritability response for growth of rainbow trout during early developmental stages was detected on the basis of full-sib and half-sib cross between the selected lines. The experiment was done in Shahid Bahonar Salmon Propagation Center, Kelardasht, Iran. Breeders were taken from the stocks maintained in this station. A bifactorial cross was done between two line using four randomly sire an...
متن کاملLactate kinetics of rainbow trout during graded exercise: do catheters affect the cost of transport?
Changes in lactate kinetics as a function of exercise intensity have never been measured in an ectotherm. Continuous infusion of a tracer is necessary to quantify rates of lactate appearance (Ra) and disposal (Rd), but it requires double catheterization, which could interfere with swimming. Using rainbow trout, our goals were to: (1) determine the potential effects of catheters and blood sampli...
