Escapes

Directorate of Fisheries

02 Jul 2019
1 salmon escapedCause: 22. Juni ble M1 lastet opp til brønnbåt Gåsø Viking og flyttet til M3. Denne fiskegruppen er merket med pit-tag og er eneste gruppe på lokaliteten som er merket og har den aktuelle størrelsen. All fisken i nota ble lastet i brønnbåten. Fisken ble satt i M3. Nota i M3 var nyutsatt og inspisert 10/6-2019. Nota i M1 ble tatt opp fra sjøen etter at fisken var lastet i brønnbåten. Vår teori er at det har vært igjen 1 stk fisk i nota, stengt inne i en fold, når nota ble heist opp. Denne har da gått i sjøen uten at noen har oppdaget dette. · Directorate of Fisheries
