Tens of thousands of juvenile king salmon are kept in cold water tanks at DIPAC’s largest hatchery in Juneau. to receive stories like this one in your inboxThe fish were on their way to be executed. One minute, they were swimming around a concrete pond. The next, they were being dumped onto a stainless steel table set on an incline. Hook-nosed and wide-eyed, they thrashed and thumped their way down the table toward an air-powered guillotine.
Today, there are hundreds of hatcheries in the Northwest run by federal, state and tribal governments, employing thousands and welcoming the community with visitor centers and gift shops. The fish they send to the Pacific Ocean have allowed restaurants and grocery seafood counters to offer “wild-caught” Chinook salmon even as the fish became endangered.
In recent years, salmon survival has dropped to some of the worst rates on record. The numbers of returning adult salmon have been so low that dozens of hatcheries have struggled to collect enough fish for breeding, putting future fishing seasons in jeopardy. “We want to stay nimble,” she said. “In some cases you may want to change the goal of the hatchery. If you find that you need to rely on it to keep a population from going extinct, you’re going to operate that hatchery program differently.”
Some die-off is natural. But the dismal survival rates of salmon bred on the Columbia today are neither natural nor sustainable. That 4% goal was established for wild populations, but in a 2015 report to Congress, 17 scientists recommended that survival rates of hatchery fish would have to be high relative to wild fish “to effectively contribute to harvest and/or conservation.”
But major shortages across the Columbia basin in 2018 and 2019 left hatcheries scrambling to find enough egg-bearing female fish. Tribal hatcheries, which are located farther upriver where salmon face a longer, harder journey, bore the brunt. They’ve beenIn 2019, Idaho’s Nez Perce Tribe needed an influx of hundreds of fish from hatcheries 300 miles away in Washington to keep breeding salmon.
“That defeats the purpose. That ceremony was for that first food coming up the river,” Patterson said. “It’s just … kinda backwards.”From the very start, federal agencies had evidence of hatcheries’ failures. But they didn’t leave themselves any other solutions. But the early hatchery efforts faded. By the 1920s, the first analysis of hatcheries at the time found “no evidence” to suggest hatcheries had effectively conserved salmon. Similar research reached the federal Department of Fisheries, a precursor to what is now NOAA Fisheries, in 1929. Amid the poor results and the Great Depression, state and federal fisheries agencies largely abandoned costly large-scale efforts to breed salmon.
