Claims (7)
1. System til sortering af fisk, hvilket system omfatter: et trawl (2) bestående af mindst én trawlpose (3, 3’, 3”), og hvor den mindst ene trawlpose (3, 3’, 3”) har en åbning, der dækker en del af et indstrømningsområde i trawlet (2), kendetegnet ved, at det yderligere omfatter: - mindst én monitoreringsindretning (6), der er anbragt i forbindelse med indstrømningsområdet, og hvor signaler kan transmitteres til en procesenhed fra den mindst ene monitoreringsindretning (6), og - hvor en mekanisme, baseret på data fra procesenheden, kan flytte åbningen i den mindst ene trawlpose (3, 3’, 3”) til en position, hvor fisk svømmer gennem indstrømningsområdet, men på ydersiden af den mindst ene trawlpose (3, 3’, 3”).
2. System ifølge krav 1, kendetegnet ved, at procesenheden er placeret på overfladen.
3. System ifølge krav 1, kendetegnet ved, at procesenheden er placeret i forbindelse med den mindst ene trawlpose (2).
4. System ifølge ét af kravene 1-3, kendetegnet ved, at den mindst ene monitoreringsindretning (6) er i form af et kamera, ekkolod, trawløje etc.
5. System ifølge ét af kravene 1-4, kendetegnet ved, at den mindst ene trawlpose (3, 3’, 3”) har et sæt skinner, som tillader montering på et stativ (7) på trawlet (2).
6. System ifølge ét af kravene 1-5, kendetegnet ved, at systemet omfatter et sorteringsgitter, og hvor mindst én af de følgende sensorer er monteret ved sorteringsgitteret: en kraftmåler, tensiometer eller vinkelmåler.
7. Fremgangsmåde til sortering af fisk ved anvendelse af et trawl (2), hvilken fremgangsmåde omfatter trinene: - monitorering af et indstrømningsområde i trawlet (2) ved anvendelse af mindst én monitoreringsindretning (6), - transmittering af signalerne fra monitoreringsindretningen (6) til en procesenhed, og - på basis af data fra procesenheden anvendelse af en mekanisme til at flytte en åbning i den mindst ene trawlpose (3, 3’, 3”) til en position, hvor fisk svømmer gennem indstrømningsområdet, men på ydersiden af den mindst ene trawlpose (3, 3’, 3”).
