The shocking collapse of one of the West Coast’s biggest wild salmon runs has prompted even cash-trapped fishermen to call for an unprecedented (空前的) shutdown of salmon fishing off the coasts of California and Oregon.
The Sacramento River salmon run is usually one of the most productive on the Pacific Coast, providing the bulk of the salmon caught by sport and commercial trollers off California and Oregon.
But only about 90, 000 adult salmon returned to the Central Valley last fall--the second lowest number on record and well below the number needed to maintain a healthy fishery. That number is projected to fall to a record low of58. 000 this year.
The council, which regulates Pacific Coast fisheries, will choose between three management options: a total ban on salmon fishing off the coast of California and Oregon; extremely limited fishing in select areas; or catch-and-release fishing for scientific research.
For consumers, it will be hard to find any Chinook, also known as king salmon. which are prized by trollers, seafood critics and upscale restaurants. There should still be abundant supplies of farm-raised salmon. but prices could be higher.
Biologists and others are trying to figure out what caused the salmon collapse so they can make sure California’s Chinook populations rebound.
There are many potential factors, because wild salmon are born in streams and rivers, migrate to the ocean when they’re juveniles and spend two to four years there before returning to spawn(产卵)in the areas where they were born. In between they have to navigate the often dangerous waters of the Sacramento Delta and San Francisco Bay.
The council has asked state and federal scientists to research possible causes, including water diversions, habitat destruction, dam operations, agricultural pollution, and ocean conditions. Many scientists point out that unusual weather patterns disrupted the marine food chain along the Pacific Coast in 2005, when thousands of seabirds washed up dead or starving because they couldn’t find enough to eat.
Researchers believe those poor ocean conditions also devastated the juvenile salmon that would have returned to the Central Valley last year. Young Chinook couldn’t find the tiny shrimp and fish they depend onto survive.

Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently 1 walked into the locker room of a rather well-known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half-dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them。These same men can be found there day after day. and, strangely enough, each one of these men had been a man of affairs and wealth, successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, else there would not have been the constant effort to escape the realities of life through scotch and soda. They knew, each one of them, that their productivity had ceased(停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.
What 1s the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible. The words were few, but they became memorably impressed on my mind: "In the sweat of the face shall you eat the bread."
To me, that has been a challenge from my earliest recollections (memories). In fact, the battle of life, of existence, is a challenge to everyone. The immortal words of St. Paul, too, have been and always will be a great inspiration to me. At the end of the road 1 want to be able to feel that I have fought a good fight, I have finished the course, I have kept the faith.

C. For some people, no way can be found to escape the realities of life other than scotch and soda.
