The Guardian: Salmon retail prices set to leap owing to infestations of sea lice

Why is salmon about to get more expensive? Sea lice have ravaged salmon farms in two of the world's largest exporting countries -- Norway and Scotland -- over the past year. And if that didn't spell trouble enough for the salmon farming industry, Chilean salmon farms have also been slammed by a highly toxic algae bloom. 

Global supplies of Atlantic salmon fell by almost 9% last year and won't rebound anytime soon, as sea lice problems worsen.
