Kyoto Environment and Development Seminar #11 June 9

Verifying seafood ecolabeling as a certification of sustainable fish stock

  • Date & Time: June 9, 2022, Thursday, 10:30-11:30 (JST)
  • Language: English
  • Venue: Zoom Web Seminar
  • Speaker: Hiroki Wakamatsu (PRIMAFF: Policy Research Institute of the Ministry of Agriculture, Forestry and Fisheries)


Seafood ecolabeling has recently shed light on a global concern about overexploitation of fish stocks. While seafood ecolabeling is positively evaluated as a tool to increase value of the certified fisheries, sometimes it is criticized its credibility and independence (or fairness) of the assessment. Targeting at the Marine Stewardship Council (MSC) certification, GutiƩrrez et al. (2012) found that the fish stocks of MSC certified fisheries are exposed three to five times lower risk than those of uncertified fisheries between 2005 and 2011. However, the number of the certified fisheries is not enough in the earlier period. Our study used more recent data between 2005 and 2018 and also integrated the MSC assessment scores to further investigate if the scores are appropriately set to preserve fish stock and control fishing rates. The obtained results generally supported the previous study by with larger variance due to larger sample size and longer period. Random forest regressions found that MSC assessment scores contribute to stock status and fishing rates, followed by species specific characteristics, and that the model predicts fishing rates more precisely than that doe s stock status.
