Froya, Norway-based Masoval's salmon farming operations have received four development permits for its closed-containment "Aqua Semi" concept, Development Director Arnfinn Aunsmo confirmed.

"We are now engaged in engineering. Construction is expected to start next year and last around 18 months," he said last week during the Norwegian Steel Association's aquaculture day in Oslo.

The first fish are expected to be released into cages by May 2022 with harvesting and processing scheduled 11 months later.
