KINGSTON, R.I., March 9 (UPI) -- U.S. residents are eating four times as much salmon as they were 20 years ago, most of it imported farmed salmon.
Researchers at the University of Rhode Island found that the value of wild salmon caught in the United States and Canada dropped from $800 million to $300 million between 1980 and 2004, the Providence Journal reported. In 1980, only 2 percent of the salmon sold globally was farmed, which grew to 65 percent in 2004.
