Sea Lice in Salmon Farming

For one of my assignments in my first year as a Marine Science student, I rsearched and wrote about the negative impact that aquaculture has on the environment, in particular, the effect that sea lice have had on wild salmon, virtually wiping out the stocks of wild salmon in Scotland.
In the New Scientist this week there is compelling eveidence that this is now also happening in Canada.
