Since the 1980s, ecological aspects of Arctica have become a subject of study after the species became commercially important along the American east coast (Kennish et al., 1994), in Icelandic waters (Thorarinsdottir and Steingrimsson, 2000) and likely in British waters (S. Davis, Cornwall Sea Fisheries, pers. comm., 2001).
