Sea scallops Placopecten magellanicus were sampled from seven Maine coastal sites with commercial gear, and the occurrence of inquiline red hake Urophycischuss was recorded. A significant positive correlation existed between fish length and host shell height. Inquiline red hake diet was primarily the amphipod Pontogeneia inermis and the decapod Crangon septemspinosa (43% and 48%, by occurrence, respectively). No evidence of predation on sea scallop hosts was found. Results suggest that inquiline red hake forage only on the bottom and in the vicinity of host sea scallops. The relationship probably serves to increase survival of age‐0 red hake and should be considered in management of fisheries for both species.
