It’s a serene sight — except for the one thing Mr. Antezana, a retired oceanographer, cannot ignore. The South American country is the top exporter of farmed salmon to the United States. For more than four decades, Mr. Antezana has watched the industry grow into one of the world’s leading producers of farmed salmon. Last year, farmed salmon was Chile’s second-largest export, generating $6.5 billion in revenue. Most of the farmed salmon eaten in the United States comes from overseas, with almost half from the fjords of Chile.
