Common Aquatic Bacteria Responsible for Fish Kill - Test results from fish sampling suggest the recent Spofford Lake fish kill resulted from the presence of a common aquatic bacteria combined with a time of year when fish were stressed from spawning activity and war water temperatures. Test results showed that no virus was present in the fish tested and that the bacteria found was Aeromonas Hydrophila. According to Fish Health Center Staff, this bacteria only becomes lethal to fish when there is another stressor to the fish. In some cases, the bacteria can infect a single fish and then multiply rapidly, causing a substantial fish kill.
