What is the MSC Blue Fish Label?

The choices we make have a ripple effect. The tuna we choose can encourage more ocean-friendly fishing practices. The shellfish we share with friends can help safeguard a species. That’s why it’s critical to look for the MSC Blue Fish Label every time you shop for seafood.

When you see the MSC blue fish label, you can purchase the seafood knowing that it’s:

  • Sustainably Sourced – The stocks are fished in such a way does not threaten the population's health⠀
  • From a Fully Traceable Supply Chain – The product you purchase can be traced from ocean to your plate, along every step of the supply chain
  • Wild-Caught – The seafood you’re consuming comes from the big blue ocean, lakes, or rivers

It’s a clear win-win for your family and the ocean. 

Why Should I Trust the MSC Blue Fish Label?

To be sold with the MSC blue fish label, seafood must come from a fishery certified to the internationally recognized MSC Fisheries Standard – a set of science-based criteria that verifies how sustainable and ocean-friendly a fishery is. The standard is developed in partnership with a wide range of top experts in their respective fields, including scientists, the fishing industry, conservation groups, and others. 

There are several fail-safes, including mandatory third-party accreditation and fish DNA testing, in place to ensure that the MSC stays impartial and fair throughout the process and to verify that the system works.

Seafood Certifications and Ratings

How do you know what to look for when you’re shopping for sustainable seafood?  What do the logos on seafood products and restaurant menus mean? Or, what do you do when there is no logo and you want to be sure you’re making a good choice for the ocean? 

Seafood certification and ratings programs are two reliable ways to trust that you’re making an ocean-friendly choice when buying fish and other seafood products. Both serve important roles in driving a more transparent seafood supply chain and encouraging companies to make continuous improvements toward sustainability. They’re independent from seafood brands, retailers or restaurants, but work with them to keep them accountable and responsible.

Here are three simple things you can do when shopping for seafood or ordering fish at your favorite restaurant:  

1. Ask the store/restaurant if they sell sustainable seafood: It always helps to ask – you might be surprised to find sustainable seafood hiding in plain sight. If a store or restaurant isn’t serving sustainable seafood yet, your question could prompt them to start! 

2. Check the logos on packaging, menus, and grocery store signage: Look for a logo on product packaging or menu that indicates environmental sustainability or responsible farming from an independent organization. For example, when you see the MSC blue fish logo, you can be sure that a specific seafood item is wild-caught, certified sustainable, traceable through the supply chain, and fighting seafood fraud and mislabeling. 

3. Look for sustainable seafood ratings: If a product isn’t certified, ratings can indicate whether your choice is ocean-friendly. For example, the Seafood Watch ratings show you which species are “Best Choice”, “Good Alternative” and which you should “Avoid” according to environmental indicators.  

Certifications and ratings can apply to both wild-caught and farmed fish.
