The Undersecretary of Fisheries and Aquaculture (Subpesca) issued a resolution effectively ending new aquaculture concessions (including for farmed salmon). The notification was made as a 10-year government moratorium on new concessions expired. The resolution will stop salmon farming from expanding into pristine areas of Patagonia, including the Los Lagos and Aysen regions. This victory comes after years of Oceana campaigning against the expansion of salmon farming in Patagonian Chile. Salmon farms are often destructive – the waste generated by enormous numbers of fish packed into pens can devastate marine environments and this high density leads to disease and excessive use of antibiotics in feed (which is released into the oceans).
