Implication

Narrative review reveals widespread physiological and behavioural disruptions from hypoxia in fishes, highlighting critical interactions with chemical contaminants.

Key Points

Synthesize existing research on the physiological, behavioral, and community-level impacts of low dissolved oxygen on fish, with a focus on interactions with environmental pollutants.
Literature review of experimental and observational evidence assessing hypoxia across cellular, organismal, behavioral, and ecological scales.
Evaluation of documented interactions between low dissolved oxygen and known chemical contaminants in aquatic environments.
Low dissolved oxygen caused by organic pollution and eutrophication alters fish behavioral patterns, impairs metabolic and cellular physiology, and shifts community composition.
Hypoxia frequently interacts with aquatic chemical contaminants, amplifying physiological stress and toxic outcomes compared to single-stressor exposures.
Significant evidence gaps persist regarding chronic hypoxia exposure, multi-species community responses, and impacts within freshwater ecosystems.
