Fisherman Mike Hudson says people are not able to spend $35 for a pound, about 450 grams, of the fish.
渔民迈克·哈德森说，人们无法接受一磅(约450克)鲑鱼35美元的价格。
Hudson has been catching and selling salmon at farmers markets in Berkeley for 25 years.

Winter-run Chinook salmon are born in the Sacramento River and travel hundreds of miles to the Pacific Ocean.
冬季洄游的奇努克鲑鱼出生于萨克拉门托河，然后游到数百英里外的太平洋。
There, they normally spend three years before returning to their birthplace to mate and lay their eggs between April and August.
它们通常会在太平洋生活3年，然后在4至8月返回出生地交配产卵。
Unlike the autumn-run Chinook that survives almost entirely from hatchery breeding programs, the winter-run is still largely wild.
与几乎全靠孵化繁殖项目才存活下来的秋季洄游的奇努克鲑鱼不同，冬季洄游的奇努克鲑鱼大部分都是野生的。
Federal fisheries officials predicted in May that more than 80 percent of baby salmon could die because of warmer water in the Sacramento River.
5月份，联邦渔业官员预测，由于萨克拉门托河的河水变暖，超过80%的幼鲑鱼可能会死亡。
Now, state officials say that number could be higher because of a quickly drying cool water in Lake Shasta.
现在，州政府官员表示，由于沙斯塔湖的冷水在迅速干燥，死亡幼鱼的数量可能还会更高。
The lake is California's largest reservoir.
沙斯塔湖是加州最大的水库。
It is filled to only about 35 percent capacity, federal water managers said this week.
本周，联邦水资源管理人员表示，它的水量只有大约35%。
"The pain we're going to feel is a few years from now," said John McManus.
约翰·麦克马纳斯说:“几年后我们将感受到这一切带来的痛苦。”
The executive director of the Golden State Salmon Association, which represents the fishing industry, said that soon there will be no wild, naturally bred salmon in the ocean.
渔业代表金州鲑鱼协会(Golden State Salmon Association)的执行董事表示，海洋里很快就不会有野生的、自然繁殖的鲑鱼了。
When Lake Shasta was formed in the 1940s, it blocked access to the cool mountain rivers where fish traditionally reproduced.
20世纪40年代沙斯塔湖形成的时候，它拦截了通往凉爽山区的河流，鱼类通常会在这些河流中繁殖。
To ensure the survival of salmon in Lake Shasta, the U.S. government is required to keep river temperatures below 13 Celsius because salmon eggs cannot live in anything warmer.
为了确保沙斯塔湖鲑鱼的生存，美国政府被要求将河流温度控制在13摄氏度以下，因为鲑鱼卵无法在13度以上的环境中生存。
The warming water is starting to affect older fish, too.
海水变暖也在影响年龄较大的鱼类。
Scientists have seen some adult fish dying before they can lay their eggs.
科学家们发现一些成年鱼类会在产卵前死亡。
"An extreme set of cascading climate events is pushing us into this crisis situation," said Jordan Traverso, an official with the California Department of Wildlife and Fish.

The West has been struggling with a historic drought and recent heat waves worsened by climate change.
美国西部一直在与历史性的干旱和最近因气候变化而恶化的热浪作斗争。
Waterways and reservoirs that are used by millions of people and wildlife are affected.
数百万人和野生动物赖以生存的水道和水库受到了影响。
As a result, the state has been moving millions of salmon raised at hatcheries directly to the ocean each year.
因此，该州每年将数百万在孵化场饲养的鲑鱼直接投放到海洋中。
That way, the fish do not travel through unhealthy waterways.
这样，鱼群就不必通过不友好的水路。
State and federal owned hatcheries take other measures to save the salmon.
州和联邦所有的孵化场还采取了其他措施来拯救鲑鱼。
For example, they keep a genetic bank to stop inbreeding at hatcheries.
例如，他们建立了一个基因库来防止孵化场里的鲑鱼出现近亲繁殖。
Fishermen and environmental groups blame water agencies for using too much water for farms.
