Chile’s Salmon Farms: On the Verge of CollapseJuly 15th, 2009
By Dan Imhoff
It seems like not a week goes by without industrial animal food production somehow making headlines–the H1N1 flu pandemic, astounding meat recalls, high levels of arsenic in chicken feed, or any of a dozen other concerns. One recent story that should have generated some rather large waves, however, has made only a minor splash. Chile’s salmon farming industry, second only to Norway’s, is on the verge of collapse.
Salmon are not indigenous to Chile, but grown in crowded cages installed in the bays and estuaries of the country’s otherwise beautiful southern fjord region. These “farmed” Atlantic salmon are fed a steady diet of wild fish–perfectly edible for humans, but more profitable when converted into “value-added” finfish. The approximately three pounds of wild fish needed to produce each pound of farmed salmon has caused some people to refer to finfish aquaculture operations as “reverse protein factories.” Equally alarming, salmon farms have become excessively dependent upon toxic pesticides to combat sea lice and antibiotic medicines to thwart viruses that can run rampant among the high concentrations of rapidly growing, penned fish–not unlike industrial-scale hog, poultry, and cattle CAFOs on land.
But the drugs are no longer working. According to industry source Intrafish, Chile’s 2009 salmon output could decline by as much as 87 percent from last year–a drop from 279,000 metric tons in 2008 to between 37,000 metric tons and 67,000 metric tons. The cause is the widespread outbreak of a virus known as infectious salmon anemia (ISA). When the virus first appeared in 2008, many offshore aquaculture companies moved their production farms further south in Chile, into waters still unaffected by ISA. Instead of lessening the problem, the industry actually spread the virus into the southern waters.
The Chilean government and regulatory agency are now implementing measures to address the crisis, but their efforts, for the time being, have been too little, too late. Chilean salmon stocks have been devastated, and this is expected to send ripple effects throughout the world’s food supply. A 20 percent shortfall in the global supply of farmed Atlantic salmon is predicted for this year and perhaps 2010 as well. The human toll in this saga is also significant, as the salmon industry has become a primary employer in the southern region of the country, and could lead to the unemployment of as many as 15,000 people. .............(more)
