Abstract

Fremgangsmåte og anordning ved tråling der det anvendes to trålposer som plasseres over hverandre og som slepes av ett trålerfartøy, der trålposene under tråling kontinuerlig tømmes for fanget sjømat/biomasse via i en bunnende av trålposene tilkoblet sugeslange som via tilhørende injektor leder til trålerfartøyet. Hosliggende trålåpningspartier av de to trålposene er sammenfestet ved minst to steder derav. Sammenfestingen skjer enten direkte i det tilfellet sideveis krefter på trålposene bevirkes av tråldører, eller skjer via festesteder på en felles hydrofoil. Den øverste trålposen er langs øvre trålåpningsparti utstyrt med et flertall av oppdriftslegemer, og nedre trålposes nedre trålåpningsparti er ved ytterendene forsynt med vekt eller lodd. Strekkliner er ført fra ytterendene av nevnte øvre trålåpningsparti og til ytterst beliggende sammenfestningssteder for trålposene, og derfra til nevnte vekt eller lodd.
