The salmon(大麻哈鱼)is one of our most valuable fishes. It gives us food and money. Every year, commercial fishing results in a harvest of over a billion pounds of salmon from the sea. Hundreds of thousands of salmon are caught each year by eager sports fishers.

In autumn, the rivers of the northwestern United States come alive with salmon. They have left the ocean on their yearly run upriver to produce eggs. Yet today, there are far fewer salmon in the northwest and elsewhere than ever before. That is because the salmon population suffers from many dangers of the modern age.

Water pollution has killed many salmon by taking away the oxygen. Over-fishing has further reduced their number. Dams are another danger because they block the ways that the salmon move from one place to another. “Fish ladders”, almost like stairs, have been built so that salmon can swim safely over the dams. But young salmon swimming to the ocean have trouble finding the ladders. They often fall to their deaths over the dams or are killed in giant hydroelectric turbines(水电涡轮机).

To fill the salmon supply, people have turned to fish farming, or aquaculture. Farm-raised salmon are Atlantic salmon. Most of them are raised in the United States, Canada, Scotland, and Norway. In a typical salmon farm, the fish remain in the places they produce eggs until they are eight inches in length. Then they are moved to large net cages by the coast. There they are fed a diet of fish meal until they reach eight pounds after about 18 months.

Aquaculture is one of the world’s fastest growing food industries. It is replacing commercial fishing in many places and is reducing the price of salmon to about a third of its earlier price. The other benefit of aquaculture is that it is allowing the wild salmon population to recover. About a quarter of a million more salmon returned to their home rivers to produce eggs each year in the mid-1990s.
