What 'North Atlantic Wild-Caught' Means on a Marine Collagen Label
These two phrases appear on a lot of marine collagen labels. They sound reassuring, but they commit the manufacturer to less than most people assume. Here is what each term actually means, and where the gaps are.
What does 'North Atlantic' mean?
The North Atlantic is a defined fishing area under the Food and Agriculture Organisation (FAO) classification system. It broadly covers the waters between North America and Europe, including the Norwegian Sea, the Barents Sea, the waters around Iceland, the North Sea and the Atlantic coast of northwest Europe. When a label says North Atlantic, it is making a geographic claim about where the fish were caught.
That is a meaningful piece of information. North Atlantic fisheries are among the most closely regulated in the world. The EU Common Fisheries Policy, the North East Atlantic Fisheries Commission (NEAFC) and national bodies set catch quotas and enforce stock assessments across these waters. This regulatory framework does not guarantee that every vessel complies, but it does mean there is oversight that does not exist in many other global fishing regions.
What the label does not tell you is which species. Cod, haddock, pollock, herring, mackerel and many others are all North Atlantic fish. Marine collagen is typically derived from fish skin, scales or bones, and the collagen yield and peptide profile can vary by species. A label that says only 'North Atlantic fish' is not required to go further than that.
What does 'wild-caught' mean?
Wild-caught means the fish were taken from the sea rather than raised in a controlled aquaculture environment. That distinction matters for some buyers. Farmed fish are often fed formulated diets and may be treated with antibiotics or antifoulants depending on the country and farm type. Wild fish eat natural diets and are not managed in that way.
For collagen specifically, wild-caught also tends to mean the raw material is a by-product of the food fish industry. Skins and scales that would otherwise be discarded are processed into collagen peptides. That is genuinely a use of material that would go to waste, which is a reasonable sustainability argument in its own right.
Wild-caught does not, by itself, mean sustainably certified. A fish can be caught wild in the North Atlantic and still come from an overfished stock. The only way to verify sustainability claims more precisely is through third-party certification, most commonly the Marine Stewardship Council (MSC). Not every manufacturer holds MSC certification, and a label can say wild-caught without it.
What the label does not tell you
Three things are commonly left off marine collagen labels. First, the species. Second, which part of the fish the collagen comes from - skin, scales and bones each produce peptides, and the processing route differs. Third, whether the collagen peptides are hydrolysed to a specific molecular weight. Hydrolysed collagen breaks the protein into shorter chains, but the degree of hydrolysis varies by manufacturer.
If sourcing transparency matters to you, the practical question to ask is not just where the fish were caught, but whether the brand can tell you the species and whether any sustainability body has independently verified the catch.
What Pump House states on the label
Our Marine Collagen Powder states that the collagen is Type I, hydrolysed, from wild-caught North Atlantic fish. The protein content is 90g per 100g. It is sold as a single-ingredient, unflavoured powder with no additives.
We do not add species information here because we do not publish details we have not verified. What we can say is that the product is 100% hydrolysed collagen from that source, and that it contains fish. Anyone with a fish or shellfish allergy or intolerance should not take it.
If you are deciding between marine and bovine collagen, the sourcing question is one of several worth thinking through. Our guide on which collagen to choose covers the practical differences. For those avoiding beef-derived products, the marine option for pescatarians sets out what that means in practice.
A note on health claims
There is no authorised GB health claim for collagen supplements. We do not make one. The sourcing descriptors on a collagen label are about where the material comes from, not what it does in the body. Those are separate questions, and the regulatory position on the second one remains unsettled.
If you want to understand how to read the numbers on a collagen label before you buy, what to look for in a marine collagen powder covers serving size, peptide content and what the protein figure actually represents.
