Sustainable Seafood What is it and How Do I Choose it?
Making responsible seafood choices is one of the most important ways that people can contribute to healthier oceans. Thankfully, there is growing consumer demand for seafood that is both ethical and sustainable, and an increasing number of people want to ensure they are making responsible decisions when it comes to their seafood choices. The challenge is that the path to making sustainable seafood choices is not a clear one.
As consumers and ocean lovers, what are the best options? Here are some of the top questions people have about choosing sustainable seafood and some actionable tips to help navigate these complex issues.
What is sustainable seafood?
Sustainable seafood is seafood that is caught or farmed (also called aquaculture) with minimal environmental and social impacts. When done correctly, sustainable seafood sourcing prevents overfishing, minimizes incidental impacts to other ocean wildlife and habitats, identifies and protects essential fish habitats, and takes into account the social and economic impacts on the communities from which the seafood is sourced.
How to decide if seafood is sustainable?
The first step is to identify the source. Some restaurants, markets, and seafood companies have made sustainability part of their operations and will advertise where their seafood is from and whether it has any sustainability certifications, however, many places do not. Even though it may feel uncomfortable, or seems like an inconvenience, it is critical that folks ask questions about where their seafood comes from and if they don’t know their supply chain, the safest option is to avoid purchasing seafood there.
Once the source of the seafood is known, using one of the guides like those listed below determines if it is sustainable:
Monterey Bay Aquarium Seafood Watch (This guide has a mobile app)
Ocean Wise
Audubon G.U.L.F. (This guide is specific to the Gulf of Mexico region and has a mobile app)
EDF Seafood Selector
WWF Seafood Guides (WWF has multiple guides that are specific to different regions)
Another way to reduce the impact of your seafood choices is to choose seafood species that are lower on the food chain, like oysters and mussels, which tend to be better options for a variety of reasons, one being that these animals are a primary food source for other animals, and so they reproduce faster than predatory species like tuna.
Other options that are low on the food chain like domestic tilapia and catfish, clams, and sea urchins tend to hit most of the boxes on the sustainability checklist.
