How to Read a Seafood Label
Five questions every label should answer — and what it means when it doesn't.
5 Questions Every Label Should Answer
A good label answers all five. Most grocery store labels answer one or two. The absence of information is itself informative.
What species specifically?
Species identification is the baseline. Without it, you cannot evaluate anything else. Generic labels like "white fish" legally permit substitution with cheaper, lower-quality species.
"Wild Alaska Sockeye Salmon" — species, origin, and stock in four words
"White fish", "Pacific fish", "seafood product" — tells you nothing and is often mislabeled
Where was it caught?
Stock health varies dramatically by region. Alaska pollock (Bering Sea) and Atlantic cod (Grand Banks) are both "North Pacific" at some level of generality. One stock is managed; the other collapsed.
"Gulf of Alaska", "Southeast Alaska", "Kodiak Island" — specific enough to identify the stock
"Pacific Ocean" — covers millions of square miles and dozens of different stock health situations
How was it caught?
Gear type determines bycatch, habitat impact, and whether the catch is traceable to a single vessel. Trawl-caught fish is rarely labeled as such because the word tests poorly with consumers.
"Longline", "Pot-caught", "Troll-caught", "Hook & Line"
No method listed — absence of this information is informative in itself
What season?
Fisheries have biological seasons. Knowing the season tells you whether the timing was appropriate for the stock and gives you a way to evaluate freshness of frozen product.
"Bristol Bay 2024 Season", "Summer Run", "Harvest: August 2024"
No date or season information — common for frozen commodity fish
Who caught it?
Named accountability is the foundation of real traceability. A product that can be traced to a specific vessel and permit can also be recalled, verified, and held accountable.
Vessel name, permit number, captain's name, or named producer
No vessel, no port, no permit — could be sourced from hundreds of boats across multiple seasons
Packaging Red Flags
These appear frequently in grocery stores, often alongside marketing language designed to obscure the lack of information.
- ✕"White fish", "Pacific fish", or "seafood" with no species name
- ✕"Sustainable" or "eco-friendly" with no certification or sourcing specifics
- ✕No catch method listed — especially if the species is commonly trawl-caught
- ✕Country of origin listed only as a broad region ("Pacific", "Atlantic")
- ✕"Product of USA" with no further origin detail — can mean caught elsewhere and processed here
- ✕No harvest date or season — frozen fish should have at minimum a year
- ✕"Previously frozen" buried in fine print after marketing copy calling it "fresh"
Restaurant Red Flags
Good restaurants are proud of their sourcing. These are signs they aren't.
- ✕"Market fish" with no species name or origin
- ✕"Sustainable" on the menu with no source named
- ✕Chilean sea bass, orange roughy, or shark (heavily overfished and frequently mislabeled)
- ✕Fish at a price point that makes no economic sense — quality fish has real costs
- ✕Staff can't answer basic sourcing questions when asked
- ✕"Fresh" at a landlocked location with no supply chain explanation
What to Look For
These signals on packaging indicate a producer who has something to prove rather than something to hide.
Vessel name or permit number
The single strongest traceability indicator — means the chain of custody goes back to the catch event
Named region + gear type
E.g., "Kodiak longline halibut" — specific enough to verify stock health and method
Season or harvest year
Demonstrates the product is managed by season, not just commodity inventory
MSC or Alaska Responsible Fisheries certification
A floor, not a ceiling — better than nothing, but follow up with gear type questions
Named producer or fishery
A company or cooperative with a name and website is accountable in a way that commodity supply chains are not
