As many fish stocks dwindle precariously, salmon farming and related aquaculture are hailed as a viable alternative.
Young salmon are placed in the circular enclosures when they’re about six inches long, where they leap and splash under netting that protects them from eagles, osprey, cormorants, and gulls. In about two years, they grow to a harvestable size of about two feet and ten pounds. A specially designed vessel sucks the mature fish from their pens and its conveyor stream immediately cleans and guts them.
Cooke Aquaculture, based in Blacks Harbour, New Brunswick, manages 15 pens in Deep Cove and Broad Cove, operating from a former fertilizer plant on Estes Head. A feeding barge sits amid the pens, which house about 450,000 salmon. About one-third of the pens are left fallow at any time.
From our upstairs windows, we can see other salmon farms at Campobello Island across the channel.
As for recipes? I’ll often make mine as sashimi.
