Atferdsbasert seleksjon i reketrål: Forsøk med MS ”Fangst” i Lyngenfjorden i Troms november 2005
(Rapport fra havforskningen, Working paper, 2007-11)I et prosjekt finansiert av Norges forskningsråd er formålet å utvikle et alternativ til ristsortering for utsortering av fisk i reketrål. Prosjektideen er å utnytte forskjeller i atferd mellom fisk og reke til å utforme ... -
Bycatch of juvenile fish in the shrimp fishery - management based on bioeconomic criteria
(ICES CM Documents;1994/T:14, Working paper, 1994)The bycatch of juvenile fish can be a major problem in fisheries with small meshed trawls, such as fisheries for shrimp, (Pandalus borealis). A sorting grid that effectively removes most of the undersized fish has been ... -
Evaluation of the Norwegian shrimp surveys conducted in the Barents Sea and the Svalbard area 1980- 1997

Forsøk med dobbel reketrål på reketrålfeltene rundt Karmøy med M/S "Nytraal" i september 1997
(Fisken og havet, Research report, 1997)Det ble utført sammenlignende fiskeforsøk med reketrål ombord i M/S "Nytraal" på rekefeltene rundt Karmøy i september 1997. Formålet med forsøkene var å sammenligne trålhøyde og avstand mellom vingespissene på en ny, ... -
Grid devices to select shrimp size in trawls
(ICES CM Documents;1993/B:35, Working paper, 1993)Discard of small shrimps and fish is a substantial problem in the fishery for deepwater shrimp in the Northwest Atlantic. In order to solve this problem, different grid devices are under development to sort out discard ... -
Improving management decisions by predicting fish bycatch in the Barents Sea shrimp fishery
(Journal article; Peer reviewed, 2011-11-20)When the bycatch of juvenile fish within the Barents Sea shrimp fishery is too large, the area is closed to fishing for a certain period. Bycatch is estimated from sampled trawl hauls, for which the shrimp yield is recorded, ... -

Preliminary Tests of a Shrimp-fish Separator Section for Use in Shrimp Trawls
(ICES CM Documents;1984/B:12, Working paper, 1984)A prototype shrimp-fish separator to be installed between the body and codend of a shrimp trawl was designed and constructed. The separator uses large square meshes to provide an escape path for fish, while funnels ... -
