A sudden, localized die-off of fish and other aquatic animals within a body of water, most often caused by a rapid depletion of dissolved oxygen following an algal bloom's collapse, a sudden temperature change, disease, or the release of pollutants or agricultural runoff. Large fish kills can leave thousands of dead fish floating on a lake or river's surface within a single day and serve as a highly visible warning sign of a broader water-quality problem.
