New Escape-Proof Fish Cage Could Lead To A Lice-Free Salmon Farm

In October this year, the first salmon were farmed in a new fish production prototype in Trøndelag, Norway. With a rigid steel construction and a water current generator, the new Aquatraz fish cage both prevents fish escape and keeps the fish in shape, while researchers from the Norwegian Institute for Water Research (NIVA) are monitoring the sea lice and water quality in the cage.

The name of the new cage concept is inspired by the high-security prison Alcatraz on Alcatraz Island in the San Francisco Bay, from which no prisoner could escape. The goal is that the  prison will be just as escape proof —and hopefully, house less sea lice.

“It is both an honour, and very interesting, to be a part of this project,” says researcher Sara Calabrese at the Norwegian Institute for Water Research (NIVA).

She and her colleague Anders Hobæk are back from their first water sampling at Aquatraz. The cage is located in Eiterfjorden, north in Trøndelag county, Norway. The coming year, NIVA will monitor the aquatic environment in the cage.
