The extent of aquatic hypoxia (low dissolved oxygen) has increased in recent times and now threatens habitats worldwide. Here, we review intraspecific variation tolerance fish on various scales: geographic among populations; genetic strains; due to laboratory acclimation; individuals coming from a given population having similar exposure history. Metrics include the oxygen level below which costs maintenance can no longer be met by uptake environment; time or at surface respiration is conducted; levels lose ability for coordinated movement. There great diversity range its association with potential underlying morphological, physiological, correlates. We advocate greater standardization experimental design, enhanced data reporting, development validation new metrics tolerance. With understanding tolerance, it might possible predict populations, strains, will fare better during hypoxic episodes; mitigate effects low fishes; design breeding protocols enhance fishes.
