    26 salmon escapedCause: De var ferdig å losse i M5 og holdt på med fortøyning til M3 da en ventil åpnet seg og fisk havnet utover dekk og videre ut i havet. Sikkerhetsnett var akkurat montert under losseslanger da hendelse skjedde, vi fikk fanget noe fisk. Det var gitter montert i spygatt, men likevel har fisk kommet seg forbi. · recaptured 1 · Directorate of Fisheries
