Summary
Light-emitting diodes (LEDs) were mounted on the lower part of a Nordmøre grid to determine if they would encourage fish to move up towards the escape outlet prior to contacting the grid. Trials were conducted to assess the size selective properties of a 19 mm bar spaced Nordmøre grid with and without LEDs. The target in the fishery is deep water shrimp (Pandalus borealis). Small fish are bycatch, with 51-100% passing through the Nordmøre grid. The use of LEDs in addition to the Nordmøre grid did not significantly affect the escape probability or the size selectivity of any species.
