Innovation May-June 2023

RAS 34 – GOLD RIVER HATCHERY EXPANSION On June 28, 2022, Grieg Seafood celebrated the completion of the Gold River Hatchery expansion project, known as RAS 34. The project is a recirculating aquaculture system (RAS) that recycles water through an aerated treatment system, providing a closed loop inside the building. The facility is completely instrumented, and all controls are automated. The RAS technology greatly reduces water usage compared to older technologies. The new facility effectively doubles Grieg’s smolt capacity and allows fish to be kept in the hatchery longer, therefore reducing the amount of time required in the ocean and greatly minimizing interactions with wild populations.
