Seafood Watch was developed by the Monterey Bay Aquarium to research and evaluate wild-caught and farmed seafood. The result is comprehensive seafood sustainability recommendations for the major seafood species consumed in the United States. Seafood Watch defines sustainable seafood as from sources, whether fish or farmed, that can maintain or increase production into the long-term without jeopardizing the structure or function of affected ecosystems.
Seafood Watch's mission is to empower consumers and businesses to make choices for healthy oceans. The goal is to shift the buying habits of consumers and businesses to support sustainable fisheries and aquaculture operations. Seafood Watch is committed to: providing seafood recommendations and background information to enable consumers and businesses to make more environmentally sound decisions; conduct outreach and marketing to generate awareness that will motivate consumers and business to support sustainable sources of seafood; and, conduct scientifically rigorous analyses and make these analyses accessible to the public or other seafood users groups.
Seafood Recommendations | New Criteria & Methodology (> Jan. 2012) | Previous Criteria & Methodology (< Jan. 2012)
Seafood RecommendationsFinal Score for Wild Fisheries = geometric mean of the four scores (Criterion 1-4).
Final Score for Aquaculture = geometric mean of the eight scores (Criterion 1-8).

Seafood Watch Scoring |
best choice* |
|
Wild Fisheries: Final score > 3.2 and no individual criterion scores of "Red" or "Critical" | |
Aquaculture: Final score between 6.666 and 10, and no Red criteria, and no Critical scores |
GOOD ALTERNATIVE*
|
|
Wild Fisheries: Final score > 2.2 and neither Management factor scores (3.1 & 3.2) are Red (<= 2.2) and no more than one criterion score of Red and no Critical scores, and doesn't meet criteria for "Best Choice." | |
Aquaculture: Final score between 3.333 and 6.666, and/or one Red criterion, and no Critical scores |
AVOID
|
|
Wild Fisheries: Final Score <=2.2, or one/both Management factor scores (3.1 & 3.2) are Red (<= 2.2), or two or more criteria score Red, or one or more Critical criteria scores. | |
Aquaculture: Final score between 0 and 3.333, or more than one Red criterion, or one or more Critical scores |
Because effective management is an essential component of sustainable fisheries, Seafood Watch issues an Avoid recommendation for any fishery scoring Red for Management (Criterion 3).
*Products posted on FishChoice primarily under the Seafood Watch ratings must be either a "Best Choice" or "Good Alternative."
