Dissolved Oxygen (DO) is one of the most important factors for aquatic animals as especially
for those who derive dissolved oxygen from the water. DO levels indicate the quality of …

The ability of fishes, amphibians, and reptiles to survive extremes of oxygen availability
derives from a core triad of adaptations: profound metabolic suppression, tolerance of ionic …

Hypoxia is a common occurrence in aquatic habitats, and it is becoming an increasingly
frequent and widespread environmental perturbation, primarily as the result of …

Hypoxia survival in fish requires a well-coordinated response to either secure more O2 from
the hypoxic environment or to limit the metabolic consequences of an O2 restriction at the …

ABSTRACT P crit–generally defined as the P O2 below which the animal can no longer
maintain a stable rate of O2 consumption (Ṁ O2), such that Ṁ O2 becomes dependent upon …

Global warming appears to favour smaller-bodied organisms, but whether larger species are
also more vulnerable to thermal extremes, as suggested for past mass-extinction events, is …

The present study was carried out to investigate effects of dissolved oxygen (DO) and fish
size (FS) on growth, feed utilization, whole-body composition, and innate immunity of Nile …

Fish cover a large size range, from milligrams to tonnes, and many of them are regularly
exposed to large variations in ambient oxygen levels. For more than half a century, there …

The hypoxic ventilatory response is arguably the single most important physiological
response accompanying the exposure of fish to lowered ambient P o 2. Increases in …

Fishes employ many and diverse strategies to increase oxygen transfer from the
environment to their tissues and/or avoid problems associated with hypoxia. Some of these …
