"The independent scientific community speaks with a single voice with regards to sea lice and their impact on wild salmon. Salmon farms kill wild salmon. There's no debate around that. It's been known and acknowledged in Europe for more than a decade."

Volpe and a team of other researchers published a paper a couple of weeks ago that says sea lice from fish farms kill up to 95 per cent of juvenile salmon that pass by.

Earlier this week, industry advocate Patrick Moore called it a fabrication to suggest sea lice from fish farms are decimating pink salmon stocksnear the Broughton Archipelago, off Vancouver Island's northeast coast.
