Includes bibliographical references (pages 7-8). "Management units for argentine were established as Div. 4VWX and as Subarea 5 by ICNAF in 1974. The rationale was administrative convenience as scientific advice provided at that time was that these areas should be combined for management purposes. Advice in 1974 was based on observed clines in vertebral counts and parasite infestations and widespread distribution of ripening fish, which suggested that there is a complex of stock units spread along the edge of the northwest Atlantic shelf. There are no new data relevant to stock structure. Not enough is known to justify definition of "best" lines for geographic separation of unit stocks, but fishable concentrations of argentine appear to be restricted to Canadian waters"--Abstract.
