Approval of Pesticide Use Permit 869-0008-18/21 Quatsino Sound

Marine Harvest Canada has received a permit for use of hydrogen peroxide (Brand name Interox Paramove 50™) at its Quatsino Sound area farm sites – Permit Use No. 869-0008-18/21. In accordance with the approval process, Marine Harvest is posting a copy on our website. This permit is a replacement of Quatsino Pesticide Use Permit 869-0002-2015/2017 that expired on December 30th 2017.

Hydrogen peroxide is a non-medicinal treatment available to BC salmon farmers and is applied as a diluted bath to a group of salmon. The bath removes small, naturally occurring, external fish parasites (sea lice) attached to the salmon. Hydrogen peroxide rapidly breaks down into harmless compounds: water and oxygen.

Paramove 50™ had been used successfully at Marine Harvest's Klemtu, Quatsino Sound, Port Hardy and Campbell River sites.  Single treatments have safely removed 95 per cent of sea lice on the company's farm-raised salmon.

Sea lice are naturally occurring crustaceans found on many fish in the ocean. The sea lice common in British Columbia waters are not a concern to human health, and rarely pose a fish health concern to salmon.

The use of Paramove 50™ will enable the company to continue its successful management of sea lice on its fish and reduce its use of the drug emamectin benzoate (Brand name Slice™) - the only effective treatment available to BC salmon farmers for the past 14 years. However, strict 3rd party salmon certification standards press for a continued reduction of Slice™ over time, so we are seeking to have another option for sea lice management.

Marine Harvest Canada is British Columbia's leading aquaculture company and supplier of Sterling brand salmon, producing 40,000 tonnes of fresh farm-raised salmon at sites around Vancouver Island and the Central Coast of British Columbia.
