Operating and controlling the environment

The environment inside Ovum E2000 is controlled and measured.

Daylight is controlled 24 hours a day inside Egget®. The fish will be supplied with the ideal amount and wavelength of light. As opposed to open net pens where oxygen can vary by season, upwelling and tide, Egget® provides an opportunity to always keep oxygen at adequate levels.

The temperature profile of the deeper layers of the fjords shows less temperature variation than in the surface. This supports better winter growth in Egget® than in open cages, probably lower growth rate during spring, but also avoids the peak temperature weeks during summer. However, in the fjords of Western Norway the temperature sum (sum of day degrees) is not very different for deep-water intake compared to the surface. In other words, we expect the growth to become more even, which will also apply to the harvest profile.
