Oxygen bioavailability is declining in aquatic systems worldwide as a result of climate
change and other anthropogenic stressors. For aquatic organisms, the consequences are …

Dissolved oxygen (DO) saturation in the water is a crucial factor in fish performance and
welfare. Exposure to low DO can affect a wide variety of functions such as metabolic rate …

The study of the molecular mechanisms of stress appraisal on farmed fish is paramount to
ensuring a sustainable aquaculture. Stress exposure can either culminate in the organism's …

The occurrence of environmental hypoxia in freshwater and marine aquatic systems has
increased over the last century and is predicted to further increase with climate change. As …

Approximately half of all fishes have, in addition to the luminal venous O2 supply, a coronary
circulation supplying the heart with fully oxygenated blood. Yet, it is not fully understood how …

In fish, the capacity of thermal acclimation to preserve cardiac mitochondrial function under
future warming scenarios is important to understand given the central roles that cardiac …

Estuarine environmental have been reported to undergo significant fluctuations in oxygen
concentrations with hypoxic conditions and subsequent re-oxygenation events being of …

Hypoxia tolerance in aquatic ectotherms involves a suite of behavioral and physiological
responses at the organismal, tissue, and cellular levels. The current study evaluated two …

Higher water temperatures and pathogens are both significant factors that negatively affect
the welfare of teleost fish. In aquaculture, compared to natural populations, these problems …

Metals are dispersed in natural environments, particularly in the aquatic environment, and
accumulate, causing adverse effects on aquatic life. Moreover, chronic polymetallic water …
