Demoralized after losing nearly 500,000 fingerling Lahontan cutthroat trout to a disease outbreak, Lahontan National Fish Hatchery officials are upbeat with the arrival of 750,000 eggs of the endangered game fish. "It's always nice when you start the whole cycle over again. It energizes us," said hatchery supervisor Larry Marchant. The hatchery south of Gardnerville received a fourth and final shipment of eggs from the Pyramid Lake Paiute Tribe Fish Hatchery, 30 miles northeast of Reno, May 24. Plans call for the 750,000 eggs to mature and develop into fingerlings over the next year. The hatchery raises about 600,000 cutthroat for annual release into Pyramid and Walker lakes and Truckee River. More than half will be released next spring into Pyramid Lake, Marchant said. The hatchery stocked Walker with 135,000 cutthroat this year, but couldn't send any to Pyramid because of the outbreak of furunculosis, a bacteria found naturally in northern Nevada's watersheds. "When you raise fish, you're going to lose fish all the time." Since then, the hatchery has been sterilized and a well has been identified as the most likely source of the disease. Lahontan cutthroat are listed under the Endangered Species Act but can be caught by anglers because of hatchery production programs.
