A population of fourbeard rocklings, Enchelyopus cimbrius, was studied in shallow water (<10 m) in eastern Newfoundland. They are nocturnal, occupying burrows in muddy substrate during the day. and often retreating into these burrows at night when disturbed. The population consisted mostly of 80–150 mm individuals, aged 2‐3 years. Feeding was observed only at night, and food consisted mostly of polychaete worms, especially the scale worm Harmorhoe imbricara . The contribution of polychaetes increased with increasing size of fish.
