New study confirms: BC salmon farms amplify sea lice; controlling lice challenging

Posted by Trish Hall on

A new scientific study, Dynamics of outbreak and control of salmon lice on two salmon farms in the Broughton Archipelago, British Columbia, published this week in the on‐line journal, Aquaculture Environment Interactions, confirms that farmed salmon can significantly amplify sea lice in coastal waters of BC, and that controlling lice outbreaks presents substantial challenges to industry, regulators, and salmon conservationists.

The study modeled the exponential growth of lice on two Broughton‐area farms located on the migration path of wild juvenile salmon, and confirmed that lice outbreaks on farmed salmon are primarily driven by louse reproduction and population growth in the farms.
