Traditional sea cage culture typically relies on natural water exchange to replace oxygen consumed by fish, which may not provide sufficient oxygen – especially during seasonal periods of high temperature.
Smolt production in Norwegian hatcheries will likely increase during the next decade to answer salmon grow-out needs. Farmers are converting existing flow-through systems to partially or fully incorporate recirculation technologies.
The Fjordsmolt RAS farm applies a relatively simple, low-cost design to produce millions of salmon smolts per year in fiberglass tanks.
A new scalable modular concept for lobster culture developed in Norway relies on automation to perform most production procedures.
While stable production of juveniles remains an issue for halibut farming in Norway, advances such as diets to replace live artemia are improving the industry.
A commercial oxygen injection system tested in Norway maintained D.O. at levels that sustained growth and increased the harvested biomass.
An intensive-culture recirculation system for farming European lobsters has been developed, with a pilot installation in Norway.
Norwegian smolt farms are located along the coast, on land, and a growing number practice partial or “tank-internal” recirculation of water.
