Fraser River sockeye have four-year cycles. There's typically a very large brood year every four years, which is dominated usually by Adams River fish. It seems like there was a perfect positive storm for the group of animals that went out for the 2010...so that would have been the 2008 smolt out-migration. Perhaps the fish farming industry—and I am a proponent of the theory that fish farms have an impact—may have dealt with some of these diseases, specifically sea lice. In any event, 2009 would have been a small run. With the perfect storm of good oceanographic conditions, perhaps the fish farms and whatever diseases were at a minimum, so that's why we can have this flip flop.
