"Fishing boats on the quay gently rock in the waves of the North Sea. They send
their catch to processing plants by the wharf, where refrigerated trucks await
out front. Commercial fishing dominates the port of Hirtshals on the Skagerrak
strait in northern Denmark. Just a few hundred meters away, however, an
innovative company is challenging this centuries-old industry.
In a closed-loop system, Danish Salmon is raising salmon not in the sea, but on
the land. “We check the fish every day,” says the company’s production manager
Arndt von Danwitz, flicking on his headlamp. With slight movements of his head,
he illuminates perforated aluminum boxes that stand in a long basin through
which cold water flows. It’s cold in the room, too — about as cold as the air
where you might find a Nordic mountain stream in winter, to “mimic nature as
much as possible,” says von Danwitz. In this frigid water, about 15 millimeters
long and very thin, are the fish. They hatched just three weeks ago, and won’t
be mature enough to harvest for another two years. “Salmon farming is for
patient people,” he smiles.
For those who do have the patience, the rewards are substantial. The world is
eating more salmon than ever. In 2021 alone, consumption increased by 13
percent. The EU and UK were the largest markets, consuming 1.28 million tons.
In the US, the appetite for salmon is also high — Americans ate some 634,000
metric tons of it in 2021."
