When you choose products with the blue fick tick, you’re choosing wild caught seafood that can be traced back to a sustainable source.

You don’t need a PhD or seafood guide to choose sustainable seafood. Just look for the blue fish tick. 

We meet international best practice guidelines and industry standards to ensure that you can trust seafood with the blue fish tick. Studies* consistently find the MSC blue fish tick to be among the most trustworthy and widely available indicators of sustainable seafood. 

Other seafood labels provide different types of information. 

Wild and sustainable

The MSC program considers the environmental sustainability of wild capture fisheries. Other schemes, such as that run by the Aquaculture Stewardship Council (ASC) consider aquaculture practices involved in responsible fish farming. We work closely with the ASC to offer buyers assurances for both wild and farmed seafood.

There are also other programs which focus on the social impacts of fishing such as labour conditions, working hours, and the treatment of crew members. While the MSC is looking to develop enhanced requirements for labour practices, our focus will remain on environmental sustainability.


The big picture

The MSC’s standard for sustainable fishing takes a whole ecosystem approach. Fisheries are assessed according to the sustainability of the fish stocks they target; their impacts on the wider marine environment including habitats and other species; and how effectively they’re managed.

Other programs may consider just one or some of these elements. For example, dolphin safe labelling focuses on the single issue of interactions with dolphins, defined by the fishing techniques used, but doesn’t consider impacts on other species or the wider environment.


Fishery focused

Assessment to the MSC Fisheries Standard considers the specific impacts and contexts of a particular fishery.  A fishery is assessed on its specific impacts to determine whether or not it meets the MSC’s requirements.

This differs from seafood recommendations or ratings, such as those produced by the Australian Marine Conservation Society or Forest and Bird. These recommendations tend to focus on species types in general and provide information for consumers or caterers to use in making informed choices. Many take MSC certification into account, but they use different criteria to determine the sustainability of the fishery, usually based on their own review of information available.

When it comes to the MSC program, all you need to do is look for the blue fish tick on seafood products to know that it comes from a fishery that has been assessed as sustainable by an independent auditor.


Truly global

The MSC's blue ecolabel is found on more than 25,000 seafood products all over the world, with around 300 fisheries certified globally from Iceland to Argentina. This makes the MSC blue fish tick the most widely used and recognised label for certified sustainable seafood. 


In-depth assessment

Assessments to the MSC Fisheries Standard take around 18 months to complete. They’re conducted by independent conformity assessment bodies (CABs) who employ a team of experts to assess the fishery. This team is required to visit the fishery, consult all relevant stakeholders and consider all available data and information in making a decision as to whether or not the fishery should be certified. Their recommendations are also peer reviewed by independent experts.


In order to process, package and sell seafood with the MSC blue fish tick, supply chain companies must be certified to the MSC Chain of Custody Standard. This ensures that seafood sold with the MSC label can be traced back to a certified sustainable source.  

DNA testing has shown that mislabelling rates for MSC labelled seafood are less than 1%

Given the high levels of mislabelling found in the open market, the results of the MSC’s DNA testing program are very positive. An independent study found an average mislabelling rate for all fish and seafood of 30%.


Meeting global best practice

Finally, the MSC runs the only wild-capture fisheries certification and ecolabelling program that meets best practice requirements set by both the United Nations’ Food and Agriculture Organization (UN FAO) and ISEAL, the global membership association for sustainability standards. The MSC is also the only global seafood certification program to be recognised as credible by the Global Sustainable Seafood Initiative (GSSI).
