Vessels fishing for shrimp (Pandalus borealis) shall use sorting grids or grates with a maximum spacing between bars of 28 mm.
A project designed to demonstrate the use of a plastic separator grate, rather than one made from aluminum, was undertaken. The grate allowed 96.6% of by-catch (cod, American plaice, turbot, and redfish) to escape unharmed. This resulted in reduced crushing of the shrimp catch and improved overall quality. The halibut release rate recorded was 100%, and the shrimp loss was 1.5%.
