dc.description.abstractThe use of the Nordmøre grid in the Pandalus fishery has significantly reduced the bycatch of finfish. Grids operate on physical separation based on size to achieve bycatch reduction. However, problems arise when the size range of fish overlaps the shrimp. In this paper results from an initial trial in northern Norway with a new selection device creating a vortex circulating out of the escape opening to force/stimulate fish are presented. The water flow (vortex) seemed to be fairly low and varied during the six observations hauls. Observations of fish behaviour showed that 0-group cod and haddock reacted to the water flow created by the deviced. The escape rate of fish varied between the six hauls possibly due to the variation in flow pattern.en
