The stock structure is not clearly understood but, based on tagging data, a distinct stock of blue shark is considered to exist in South Pacific besides the North Pacific with demarcation near the equator (Kleiber et al., 2009; Sippel et al., 2011; ISCTTS, 2013).
Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.
