In the western United States, tropical river fishing, indestructible industry

Thousands of baby salmon are dying in one California river, and an entire dangerous salmon race could be lost in another. Once adult fish salmon enter the Pacific Ocean, warming waves and prolonged droughts raise the temperature in western Judea and amphibian fish from Idaho to California.

Hundreds of thousands of young salmon are dying in the Klamat River in northern California, destroying the water-borne parasites caused by drought. And wildlife officials say the Sacramento Salmon River is “completely extinct” due to unusually hot water. Disasters in the one-year-old section of young salmon can have a lasting effect on the general population and can shorten or stop fishing season, as climate change continues to make the West warmer and drier. That could be difficult for the $ 1.4 billion commercial salmon fishing industry in California alone.

The downturn has already pushed up retail prices for salmon, hurting customers who say they can’t afford $ 35 per pound, said Mike Hudson, who has spent the past 25 years capturing and selling salmon at Berkeley Farmers’ Markets. Hudson said he planned to leave and sell the 40-foot (12-meter) boat because “it will get worse.” Winter-running Chinook Salmon crossed the Sacramento River hundreds of miles into the Pacific Ocean, where they lay their eggs between April and August before returning to their homeland.

Winter races are still rampant in the wild, unlike Chinook, which survives the fall of cattle ranching. Federal fishing officials predicted in May that more than 80% of baby salmon could die from hot water in the Sacramento River. State wildlife officials say the number is likely to rise in the fast-paced pool of Lake Shasta. California’s largest reservoir is only about 35% full, federal water managers said this week.

“We feel sick a few years after the birth of a natural salmon in a few oceans,” says John McManusus, executive director of the Golden State Salmon Association, which represents the fishing industry. When Lake Shasta was created in the 1940s, it blocked access to the cool mountain rivers where fish normally grow. To ensure their survival, the US government has to maintain a river temperature below 56 degrees Fahrenheit (13 degrees Celsius) because salmon eggs are generally unable to withstand anything hot. Warm water also begins to affect older fish. Scientists have observed that some adult fish die before they lay their eggs.

“Extreme weather events are pushing us into this crisis,” said Jordan Travezo, a spokesman for the California Department of Wildlife and Fisheries. The West has been battling a historic drought, and recent heat waves have exacerbated climate change, straining waterways and reservoirs that hold millions of people and wildlife. As a result, every year the state travels the dangerous lowland voyage, transporting millions of salmon to the ocean.

State and federal conservation agencies take other unusual measures to protect invented salmon stocks, such as preventing them from starving in hatcheries and releasing them at critical stages of life, when they can identify and return to their native water. Fishermen and environmental groups have blamed water agencies for diverting too much water to farms, leading to severe salmon deaths and near extinction.

“We know that climate change will make such years more common, and the agencies must do more to manage the situation,” he said. Wild salmon and steel in the Pacific Northwest. He added: “We need some real change in how rivers are to survive.”

California’s wildlife authorities have decided not to release more than 1 million young Chenuk salmon into wildlife along the Lammat River near the state of Oregon. If he goes according to plan, he will be the first to remove four of the six dams in Klamat and return fish to the upper river, because he is traveling a lot in this part of salmon. In the West, officials are facing similar concerns about overfishing.

In Idaho, authorities realized that the migration of the endangered Sokeke salmon would not bring hundreds of miles of hot water to their homes, so they flooded the snake’s river with cold water, then trapped and loaded the fish into chicks. And environmentalists are trying to force dam operators on the Portland, Oregon, Snake and Colombian rivers this month, arguing that more water will be released on dams that block salmon, the effects of climate change and more recent heat waves. Already disappearing.

Low water levels also affect recreational fishing. Authorities in Wyoming, Colorado, Montana, and California are urging fishermen to catch fish in cold water to reduce the effects of low oxygen levels. According to scientists, the salmon population in California has grown again after a drought because they benefited from evolution and the rainy and wet years to save the Mediterranean climate. But prolonged drought can lead to the extinction of some salmon races.

“We are at a critical juncture in terms of drought,” says Andrew Rappel, an ecologist at Davis University in California. He says the West is moving to an area where water shortages are becoming more frequent. Hudson, a fisherman, says he spends days at sea when the salmon season is long and he can catch 100 fish a day. He said he was lucky to have 80 to sell in the market this year. “Retiring is smart, but I can’t bring myself because these fish have been so good to us all these years,” Hudson said. I can’t stay away from him.
