Summary: 
Artificial lights were attached to each the rigid-grate BRD and fishing lines in trawls for ocean shrimp (Pandalus jordani) off Oregon. Bycatch of eulachon (Thaleichthys pacificus), a threatened anadromous smelt species, was reduced on trawls with lights on the fishing lines as it was for slender sole (Lyopsetta exilis) and darkblotched rockfish (Sebastes crameri), without affecting target catch.
