A federal decision to shut down 15 open-net Atlantic salmon farms around B.C.'s Discovery Islands is being lauded as a win for protecting wild salmon, and a significant blow to the fish-farm industry — all while reigniting a decades-old debate between industry and scientists. The decision from Ottawa came just weeks after a Fisheries and Oceans Canada (DFO) report found no "statistically significant association" between sea lice infestations among wild juvenile chum and pink salmon and the fish farms they migrate past along the B.C. coast.
