    Abstract

    A link between D. eleginoides stocks in Subareas 48.3 and 48.4 has been speculated for some time. Different growth rates and maturity suggest that there is no regular exchange between the two areas, but tag recapture data clearly show a small number of toothfish moving between them, while genetic analysis also indicates that both stocks belong mostly to the same genetic population. Here we examine the information currently available.
