Escapes

08 Sep 2025
9 salmon escapedCause: Årsaken til hendelsen antas å være en mekanisk svikt i sirkulasjonssystemet under omkobling fra UV-UT-sirkulasjon til åpen sirkulasjon. De observerte dårlig gjennomstrømming i filteret om bord, og mange partikler i vannet (urent vann), og det ble besluttet å gå over til åpen sirkulasjon for å få et renere miljø i rommet. Videre undersøkelser vil avdekke faktisk årsak. · recaptured 1 · Directorate of Fisheries
