Escapes

Directorate of Fisheries

15 salmon escapedCause: Det er uklart for oss hvorfor der plutselig kom levende fisk ut av slangen. Vi var ikke foreberedt på en større mengde fisk under denne operasjonen, og derfor gikk fisken fra slangen over silkassen og opp i dødfisk kassen som ble fuldt opp og det rant over. · recaptured 1 · Directorate of Fisheries

Wellboat visits
