We evaluated seafood against the Good Food Standard, looking at species accuracy, origin and fishing method disclosure, third-party certification, and supply chain transparency.
What you should know
The wild vs. farmed debate misses the point. A well-managed salmon farm in Norway produces better, more consistent fish than wild-caught salmon from a depleted or poorly managed fishery. Conversely, pole-and-line caught tuna from a certified small-boat fishery is significantly better for ocean health than longline trawling regardless of whether the tuna is "wild." The meaningful questions are: where, how, and under what management.
Species identification is a measurable, recurring problem. DNA testing by the ocean conservation group Oceana found seafood sold in the US as "red snapper" was mislabelled 87% of the time, and "sea bass" 55% of the time — usually replaced with cheaper, less-regulated species. A separate genetic study across 19 European cities found lower mislabelling at retail (under 5%) but rates climbing toward 30% in restaurants and catering, with anchovy, hake, and tuna substituted most often. The pattern holds across markets: a cheaper species sold under a more valuable name. MSC certification with chain-of-custody traceability provides the most reliable third-party verification of species identity.
Canned seafood is an underrated category. A tin of well-sourced, pole-and-line tuna in good olive oil from a traceable fishery is a genuinely excellent product — but it looks identical on the outside to a tin of commodity tuna. The distinction is in the details: species (yellowfin vs. skipjack), catch method, origin, and what it's packed in.
Labour standards in seafood supply chains vary widely by region and certification body. Third-party audits and certifications like MSC's Chain of Custody standard provide documented verification of fishing and labour practices. Transparent, shorter supply chains make it easier to verify both quality and sourcing.
Three things to check on any seafood
Species name
Atlantic salmon vs. Pacific; yellowfin vs. skipjack; tiger prawn vs. vannamei. The specific species tells you about flavour, sustainability status, and supply chain transparency.
Catch or farm method
Pole-and-line, trolled, or FAD-free for tuna. Dredged vs. hand-dived for scallops. Open-net vs. recirculating aquaculture systems. These distinctions matter for quality and ocean impact.
Third-party certification
MSC (Marine Stewardship Council) for wild-caught; ASC (Aquaculture Stewardship Council) for farmed. Neither is perfect, but both require independent auditing — which is more than an uncertified label.

Atlantic Ocean, Portugal
The same wild-caught Atlantic sardines from Bela-Olhão, lightly wood-smoked and packed in olive oil with natural lemon flavour. The smoking is real — applied to the fish before packing, not simulated with liquid smoke additives. A good entry point for those new to tinned fish: the lemon and gentle smoke soften the intensity of the sardine without masking it.

Bela-Olhão has been canning sardines on the southern Portuguese coast since 1925. Their sardines are wild-caught in the Atlantic during the summer season, when the fish are at their fattest and most flavourful. Hand-packed and cooked just once, in the can. The result is a firm, intact fillet in genuinely good olive oil — not broken up in brine or vegetable oil. A straightforward, honest product from a century-old tradition.

Fishwife is a US brand bringing the European tinned fish tradition to a wider audience. Their smoked Atlantic salmon is sourced from ASC-certified farms in Scotland and Norway, cold-smoked before packing. The brand is transparent about its sourcing and has built its identity around ingredient honesty — making quality tinned fish an everyday pantry item rather than a specialty purchase.

Bonito del Norte is the finest tuna in the North Atlantic. Ortiz has been hand-packing it from the Bay of Biscay since 1891, using pole-and-line methods that target individual fish rather than whole schools. Packed in olive oil, the flesh stays firm and distinctly flavoured — not the flaked, salted filler of mass production. A benchmark for what canned tuna can be.

The Cantabrian anchovy (bocarte) is the gold standard of preserved anchovies. Ortiz catches the fish in spring, when they are fattest, then cures them in salt for 6 to 12 months before cleaning and packing in olive oil. The result is a deeply savoury, silky fillet — far removed from the harsh, overly salty anchovies found in most supermarkets. Used by cooks across Europe and beyond to add depth to almost any dish.

White anchovies (boquerones) from the Bay of Biscay, marinated in white wine vinegar and packed in olive oil. A different product from the salt-cured red anchovy: milder, firmer, and more accessible to those unfamiliar with preserved fish. Patagonia Provisions sources from the same northern Spanish waters that produce some of the world's finest anchovies.
Read the full evaluation →Humboldt Current, Chile
Jack mackerel from the highly productive Humboldt Current fishery off Chile. Patagonia Provisions works with fisheries operating under science-based catch limits, using purse-seine methods designed to reduce bycatch. Mackerel is a fast-growing, short-lived species that recovers quickly from fishing pressure — one of the most rational seafood choices available.
Read the full evaluation →Lummi Island, Washington, USA
This pink salmon is caught by reef net off Lummi Island — one of the oldest and most selective fishing methods, practiced for centuries by indigenous communities in the Pacific Northwest. Reef nets catch salmon gently and individually, releasing non-target species unharmed. Patagonia Provisions supports the continuation of this practice. A product with a fully traceable story from water to tin.
Read the full evaluation →North Pacific Ocean
Wild Planet sources albacore tuna from small-boat, troll-caught fisheries in the North Pacific. The fish are younger and smaller than those caught by industrial longline — which means lower mercury and a shorter supply chain. Packed without added water or broth: just tuna and sea salt. What the label says is what is in the can.
Read the full evaluation →Pacific Ocean
Pacific mackerel is among the most nutritionally dense and sustainably harvested fish available. Wild Planet sources from Pacific fisheries using methods that minimise bycatch. Like all Wild Planet products, the mackerel is cooked once, in the can — not pre-cooked, drained, and then reliquified with added water or broth.

Pacific sardines are a fast-reproducing, short-lived fish — one of the most sustainable protein sources available anywhere. Wild Planet packs them in extra virgin olive oil with minimal processing, leaving the fish as whole as possible. Rich in omega-3 fatty acids, calcium, and vitamin D. A practical, nutritious everyday food with a clean ingredient list.
