<br /> <p>Tens of thousands of fish died overnight on November 15 in the Shinnecock Canal on Long Island, New York. The fish died of hypoxia, often caused by a lack of oxygen and a high density of fish in the water.</p><p>“The large school of fish was most likely chased into the canal by other predatory fish,” the New York Department of Environmental Conservation said in a statement. The Suffolk County Health Department has taken water samples to test for pathogens and pesticides as a precaution. Credit: YouTube/Chris Paparo via Storyful</p><br />
