Summary: Climate warming has negative consequences for fishes, reducing their aerobic scope and performance. The hypothesis that fishes select temperatures to maximize their aerobic scope remains controversial. A study on zebrafish found that their temperature preference is influenced by factors other than maximizing their aerobic scope.

Summary: This article investigates the metabolic scope, performance, and tolerance of juvenile European sea bass reared under high water temperatures. It finds that European sea bass can maintain high performance at 28 degrees Celsius, but critical survivability thresholds appear sharply close to 33 degrees Celsius.

Summary: This study investigated the impacts of climate change stressors on the Australasian snapper in New Zealand. The results showed that the snapper's metabolic performance remained high even in warm conditions, and they were able to adapt well to hypoxia. Therefore, despite the threat climate change poses to marine organisms, a temperature of 25°C may be metabolically optimal for the Australasian snapper in Northern New Zealand.

Summary: Aquatic ectotherms may experience changes in hypoxic performance due to climate warming and thermal acclimation. Most studies focus on testing hypoxic responses at temperatures matching organisms' acclimation temperatures, limiting the interpretation of thermal acclimation effects. Some studies suggest that warm acclimation may improve hypoxic performance in aquatic ectotherms.

Summary: Aerobic metabolic scope is a useful metric for assessing the performance of aquatic animals at different temperatures. Temperature acclimation has limited effects on the breadth and amplitude of the thermal performance curve for aerobic scope, with the metabolic phenotype of fish potentially being more dependent on mean daily temperature than daily temperature range.

Summary: The study on Antarctic marine invertebrates exposed to different thermal stresses reveals highly individualized responses in gene expression profiles among different species. There is no evidence for a common response across different temperature treatments within species, and no shared differentially expressed genes across species at the same thermal ramping rates.

Summary: P-crit is the critical oxygen partial pressure below which an animal's metabolic rate is unsustainable, while alpha reflects the oxygen supply capacity. The relationship between alpha values and metabolic rate is stronger than that between alpha and P-crit, indicating that P-crit is more of a reflection of oxygen supply capacity than hypoxia tolerance.

Summary: Experimental hyperoxia has been shown to enhance the maximum oxygen uptake capacity of fishes, and this benefit can persist under chronic conditions. The research suggests that experimental hyperoxia can affect the metabolic structures and processes of fish, resulting in improved aerobic performance under climate warming.

Summary: This study highlights the thermal tolerance and performance of juvenile meagre under different high water temperatures, showing that the species thrives best between 24 and 29 degrees Celsius, while 34 degrees Celsius poses challenges to its growth and physiology. Short exposures to high temperatures may be tolerated with acclimation, but prolonged exposure leads to decline in overall performance, making this aquaculture species vulnerable to global warming.

Summary: Research suggests that hypoxia may impair fish cardiac and metabolic responses to increased temperatures, potentially making coastal species more vulnerable to climate change-related heat waves than previously thought. Moreover, the limited cross-tolerance and physiological plasticity in fish following hypoxia acclimation highlight the need for further study in this area.

Summary: This study examined the metabolic rate and thermal tolerance of virile crayfish along a latitudinal gradient. The results showed a positive relationship between latitude and crayfish metabolic rate, and high latitude populations were more thermally sensitive. These findings reveal the thermal adaptation differences among different populations.

Summary: The research proposes a hypothesis about water-breathing ectothermic animals, suggesting that they regulate peak specific dynamic action response during times of warming by reducing meal sizes to protect postprandial residual aerobic scope, leading to reductions in growth.

Summary: The study investigated the prediction of individual FE in European sea bass, identifying significant effects of temperature and population on FE and RMR. However, individual FE and RMR were not significantly correlated, indicating a need for further investigation into the relationship between metabolic rate and feed efficiency.

Summary: This study found that coronary perfusion plays a significant role in improving fish tolerance to environmental stressors such as hypoxia and warming. Blocking coronary blood flow negatively affects cardiac function and overall tolerance to hypoxia and heat, highlighting the importance of coronary circulation in maintaining cardiovascular function during extreme environmental conditions.

Summary: The study found that exhaustive exercise in hyperoxia can increase the maximum oxygen consumption rate and aerobic scope in rainbow trout by improving cardiac function and blood parameters. This suggests that hyperoxia can enhance maximal cardiac performance, tissue oxygen delivery, and maintain a higher maximum oxygen consumption rate.

Summary: Recent evidence suggests that environmental hyperoxia can enhance cardiorespiratory performance and increase thermal tolerance in fish, helping them cope with extreme heat waves caused by climate change. This effect is mainly due to improved cardiac function and increased tissue oxygen supply capacity. Additionally, available literature data show that hyperoxia can improve thermal tolerance in a large number of fish species.

Summary: Rainbow trout acclimated to sea water have higher resting cardiac output and aerobic scope compared to freshwater-acclimated trout to meet the higher metabolic needs of osmoregulatory functions. However, cardiac performance and aerobic scope are significantly impaired after exhaustive exercise due to atrioventricular block caused by coronary ligation. This study demonstrates that cardiovascular function and oxygen carrying capacity are more dependent on coronary perfusion in sea water-acclimated trout.

Summary: The study demonstrates that hyperoxia can increase maximal oxygen consumption rate in rainbow trout, achieved through increased cardiac output and arterial-venous oxygen content difference. Hyperoxia protects arterial oxygenation, leading to higher arterial oxygen content and A-V O-2 content difference post-exercise.

Summary: This review comprehensively synthesizes the effects of hyperoxia on fish, covering influences on cardiorespiratory function, acid-base balance, and oxidative stress. While hyperoxia can cause hypoventilation and increase aerobic metabolic rate in fish, current evidence suggests it does not significantly impact growth.
