Sea lions continue to prowl fish farms on Vancouver Island91Ƶs west coast as federal officials work to ensure efforts to thwart them aren91Ƶt putting them at risk

The Department of Fisheries and Oceans Canada said it is monitoring sea lion activity around Cermaq Canada salmon farm sites near Tofino after area residents began ringing alarm bells in April. Dozens of sea lions were spotted inside Cermaq91Ƶs Rant Point site, feasting on the farmed Atlantic salmon within.

91ƵDFO staff have been on a number of sites and remain in constant contact with farm operations to ensure accurate information and that deterrent efforts are being safely put in place,91Ƶ a DFO spokesperson told Black Press Media via email.

They added that DFO has 91Ƶa strict requirement that no sea lions can be euthanized,91Ƶ and that aquaculture licences require operators to ensure as little risk to marine mammals as possible.

91ƵAttempts to deter the sea lions and to remove them from the net pens, with least harm to the animals, have been ongoing in consultation with DFO biologists,91Ƶ they wrote. 91ƵCermaq91Ƶs Conditions of Licence do not allow acoustic deterrents below water. However, DFO does permit the use of deterrent noise, such as an air cannon, above water.91Ƶ

The spokesperson said Cermaq is required to take all reasonable steps necessary to free any sea lions from their farms and that DFO will investigate any reports of sea lions being harmed.

91ƵDFO staff have witnessed reduced sea lion activity at these sites in recent weeks,91Ƶ they wrote. 91ƵDFO continues to work with industry to develop effective strategies to deter sea lions, including the adoption of infrastructure that is resistant to predator attacks. This includes stronger predator netting, higher perimeter fencing and upgraded electric fencing.91Ƶ

Cermaq has yet to respond to a Black Press Media request for comment.
