These methodologies are risk based and are regularly updated so that they remain relevant and scientifically robust. Although the methodologies can be accessed publicly, only trained assessors should use them to ensure that they are applied in a consistent way.
For wild-capture fisheries, this includes scientific information on the status of the stock or vulnerability of the species to fishing pressure, along with environmental impacts of the fishing gear used and the effectiveness of the fishery management to ensure environmental sustainability.
For farmed species, the methodology looks at the use of resources such as water, energy and feed, the impacts that a specific aquaculture production system has on the surrounding environment, wildlife and communities, and the applicable management framework.
Fisheries and aquaculture experts conduct assessments of fisheries and aquacultures pursuant to these methodologies, making use of publicly available scientific data and documents to assess the environmental sustainability of seafood origins.
