Cooke invests in green tech to combat sea lice

Cooke Aquaculture is boosting its sea-lice management tools with addition of the Thermolicer technology — a Norwegian invention that uses warm-water baths to remove sea lice.

“The Thermolicer exploits a vulnerability of sea lice that we know do not tolerate sudden changes in water temperature. Sea lice are immediately sensitive to sudden temperature changes. By suddenly heating the lice, it will fall off the fish,” said Tore Laastad of Steinsvik, which designed the technology.

Blacks Harbour-based Cooke Aquaculture said trials of the technology last summer proved it to be 98 percent effective at removing the lice without harming the fish. It has since equipped one of its vessels — the Miss Mildred — with the technology and brought it into service recently.

“This is an exciting evolution in sea lice management for us. Thermolicer is a simple and effective treatment that further reduces our need to use chemicals or medicines,” said Joel Richardson, Vice President, Public Relations for Cooke Aquaculture.

He added that it is the first time that the Norwegian technology is being used in Atlantic Canada to combat sea lice.
