Zebra Mussels Discovered in Trout Hatchery Water Supply
The New York State Department of Environmental Conservation announced, invasive zebra mussels were discovered in Delta Lake, which serves as DEC's Rome Fish Hatchery water supply.  The department immediately launched an investigation and through subsequent water testing at the hatchery, confirmed the presence of zebra mussel veligers (larvae) in an outdoor raceway.

With nearly 160,000 pounds of brook, rainbow and brown trout annually, the Rome Hatchery is one of DEC's largest hatcheries. DEC officials say that hatchery managers are currently developing short- and long-term strategies to limit the spread of the mussels and will work towards returning the hatchery to normal production as quickly as possible.

Fish from the Rome hatchery will only be stocked in waters currently inhabited by zebra mussels. Fisheries managers will have to determine the type and number of fish stocked into individual water bodies; some waters may receive a reduction, others an increase in stocking, while other waters may not be stocked at all.

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.
