Escapes

Directorate of Fisheries

14 Jan 2023
2 salmon escapedCause: Det skulle være en operasjon med flytting av fisk til ny merd på lokaliteten. Notposen var trang som følge av krymping etter notvask/service. Dette førte til at håndlista bikket innover og ble mye lavere og mye mer deformert enn normalt når vi strammet opplinertauene for å låse av bunnen helt oppe (forberedelse til å tre kulerekke). Siden nota er så trang, ble det mange meter med helt slett lin, som fungerte som en trampoline. Dermed hoppet to svimere bortover linet og over kanten på hoppenettet. Ingen rakk å reagere før fisken gikk i sjøen. · recaptured 1 · Directorate of Fisheries

Wellboat visits

Visits are derived by us from the Coastal Administration's AIS positions: a fish carrier stationary within 500 metres of the farm for at least 30 minutes. The AIS archive lags about 17 days. A visit is not proof of infection.
