Energetics of locomotion in warm-bodied fish.
Most fishes are poikilothermic-Le. their body temperature is within a few degrees of ambient unless ambient is changing rapidly. The exceptions are certain sharks and true tunas. Little is known about the locomotion and energetics of warm-bodied sharks. Our review focuses on a few species of tunas but draws on information from other fish (especially salmonids) to fill in the gaps in our underst...
متن کاملHeat exchnage in the black skipjack, and the blood-gas relationship of warm-bodied fishes.
The black skipjack, Euthynnus lineatus, uses a centrally located vascular heat exchanger to maintain core body temperatures warmer than ambient sea water. The heat exchanger is composed of the dorsal aorta, the posterior cardinal vein, and a large vertical rete. The dorsal aorta is embedded in the posterior cardinal vein and is completely bathed in venous blood. Skipjack hemoglobin appears simi...
متن کاملTemperature-induced Changes in Blood Gas Equilibria in the Albacore, Thunnus Alalunga, a Warm-bodied Tuna
Samples of unbuffered, whole blood from freshly-caught albacore (Thunnus alalunga Bonnaterre) were equilibrated at 5, 10, 15, 20, 25, 30 and 35 °C and at 0 and 1 % CO2 for construction of oxygen dissociation curves. A strong Bohr effect ( — 1-17), a negligible Root effect, and a reverse temperature effect (AH = +1-72 for 0 % CO2 and +0-26 for 1 % CO2) characterized these hyperbolic (Hill's n = ...

متن کاملEnvironmental Factors Affecting Large-Bodied Coral Reef Fish Assemblages in the Mariana Archipelago
Large-bodied reef fishes represent an economically and ecologically important segment of the coral reef fish assemblage. Many of these individuals supply the bulk of the reproductive output for their population and have a disproportionate effect on their environment (e.g. as apex predators or bioeroding herbivores). Large-bodied reef fishes also tend to be at greatest risk of overfishing, and t...
