Mach et al. (2011) found some regional differentiation correspondent to biogeographic provinces contrarily to previous assumptions of homogeneity (Johnson, 1975; Conover, 1998). Clark et al. (2010) also found differences in otolith chemistry. Stock structure of Atlantic silverside is not totally understood. Thus the Prince Edward Island where the unique Canadian fishery takes place is considered as a unit for assessment and management purposes (DFO, 1996; DFO, 1997; DFO, 2010).
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.
