Bait consisting of 3x3 cm pieces of dried squid and dried kelp (kombu) purchased at a local asian grocery store (HMart) were attached to wooden dowels via transparent fishing line. Dowels were inserted into the substrate  in the upper right hand corner of each quadrat so that squid and kelp bait rested on the substrate. Both were placed far enough from each other so as to not overlap. Bait was checked daily and status was noted - whether partially consumed or completely missing (i.e., consumed).
