Moving hatchery salmon fry by truck is a good strategy during drought years, as reported by the Sacramento Bee.
More than 12 million juvenile hatchery salmon will get a truck trip downstream starting Monday to help them circumvent the harmful effects of drought on the Sacramento River.
The U.S. Fish and Wildlife Service announced the plan Friday, as a way of bolstering survival rates for the fish. The Sacramento River, compromised by California’s persistent drought, is too low to provide adequate food and protection from predators, potentially jeopardizing a crop of fish that supports the state’s commercial and recreational salmon fishing industries.
Agency spokesman Steve Martarano said it will take 22 days to transport all the fish in tanker trucks from Coleman National Hatchery near Red Bluff. The first salmon will be trucked in a trial run on Monday, with additional shipments continuing Tuesday, if all goes well. Each delivery will deposit the fish back into the Sacramento River near Rio Vista.
Each truck holds about 2,800 gallons of water and 130,000 salmon smolts – juveniles 4 to 6 inches long – and is climate-controlled to maintain a water temperature between 55 and 60 degrees.
