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 …

Shallow or near-shore environments, such as ponds, estuaries and intertidal zones, are
among the most physiologically challenging of all aquatic settings. Animals inhabiting these …

Dissolved oxygen (DO) undountedly affects fish distribution, metabolism, and evern survival.
Intensive aquaculture and environmental changes will inevitably lead to hypoxic stress for …

Many fish encounter hypoxia on a daily cycle, but the physiological effects of intermittent
hypoxia are poorly understood. We investigated whether acclimation to constant (sustained) …

Hypoxia is one of the most significant threats to biodiversity in aquatic systems. The ability of
high-latitude fish to tolerate hypoxia with histological and physiological responses is mostly …

The gills of many fish, but in particular those of crucian carp (Carassius carassius) and
goldfish (Carassius auratus), are capable of extensive remodeling in response to changes in …

Sufficient dissolved oxygen (DO) is essential for most teleosts. However, high-density
aquaculture and fluctuating environmental factors can result in hypoxic stress in golden …

Hypoxia is an adverse environmental condition for fish that can have multiple effects.
Compared to the natural environment, high-density farming of Schizothorax prenanti is more …

An organism's critical oxygen tension (P crit) reflects its ability to extract environmental O 2.
Consequently, P crit has been used as an indicator of hypoxia tolerance in aquatic animals …

Climate change is leading to rapid change in aquatic environments, increasing the mean
and variability of temperatures, and increasing the incidence of hypoxia. We investigated …
