"A virus called infectious salmon anemia, or I.S.A., is killing millions of salmon destined for export to Japan, Europe and the United States. The spreading plague has sent shivers through Chile’s third-largest export industry, which has left local people embittered by laying off more than 1,000 workers.
It has also opened the companies to fresh charges from biologists and environmentalists who say that the breeding of salmon in crowded underwater pens is contaminating once-pristine waters and producing potentially unhealthy fish.
The salmon companies “are robbing us of our wealth,” said Victor Guttierrez, a fisherman from Cochamó, a town ringing the Gulf of Reloncavi, which is dotted with salmon farms. “They bring illnesses and then leave us with the problems.”"
