Figure 1.
Sustainability of certified and uncertified seafood.
Current (i.e., most recent year with available information) biomass and exploitation rate for (A) individual certified (n = 45); (B) all uncertified (n = 179); and (C) uncertified stocks that went through pre-assessment and were not recommended for certification (n = 25). Data are scaled relative to BMSY and uMSY or FMSY (the biomass and exploitation rates or fishing mortality rates that produce maximum sustainable yield). Contour colors show probability of occurrence (red indicates the highest probability and blue the lowest). Vertical and horizontal solid lines represent reference points common to all fisheries (B/BMSY = 1 and u/uMSY or F/FMSY = 1). Dotted lined represents B = 1.3BMSY and dashed line B = 0.5BMSY. Footnote: New assessments for some fish stocks were released while this paper was in press, but this figure was not updated to maintain consistency in year of release.

Figure 2.
Time trends of current biomass (total or spawning) relative to biomass levels at the time of MSC assessment for stocks with available information and more than 5 years of certification.
Colors represent current stock status (green to yellow: B>BMSY; orange to red: B<BMSY) and dots represent most recent year of available information (as per Table S1).

Performance of MSC-certified and uncertified fisheries.
Long term trends (1970–2009) of biomass relative to their targets levels (i.e., estimated biomass at which the maximum sustainable yield should be obtained: BMSY; median ±S.E.). BMSY is set to 1 (broken line).
