Salmon is one of my favourite fish. Now that is threatened too.

Wild salmon on Canada's west coast are being driven to extinction by parasites from nearby fish farms, a study claims.
Wild pink salmon around the Broughton Archipelago are declining rapidly and will die out within 10 years if no action is taken, say researchers.

They say the data, published in Science, raises serious concerns about the global expansion of aquaculture.

Sea lice from farms are known to infect wild salmon, but until now the impact on wild populations has been uncertain.
