Escapes

Directorate of Fisheries

03 Jun 2022
3 salmon escapedCause: Under behandling mot lus, valgte man å bruke muligheten for å sortere ut Rognkjeks til avliving. Mot slutten av behandlingen kom der plutselig veldig mye Rognkjeks på kort tid gjennom avsileren. Systemet klarte ikke å svelge denne mengden og det rant over på baksiden og fisk endte på dekk. 3 stk taper laks endte på sjøen ilag med 2 stk rognkjeks. Rømningssikring var på plass men ikke på baksiden. · recaptured 1 · Directorate of Fisheries
