Can you name the exact fish species in fish oil?
Most “fish oil” products do not disclose a single fish species. Many are made from fish harvested from broad sources (for example, small pelagic fish), and the label often uses terms like “fish oil” or “omega-3s” without naming a specific species.
What does the label usually tell you (and what it doesn’t)?
In many cases, you’ll see information such as:
- the omega-3 amounts (EPA and DHA) per serving
- whether the oil is from “fish” generally
- sometimes the geographic origin or “species” wording, but that is inconsistent across brands
If the manufacturer names a species, it’s usually shown directly on the label or in product documentation. If it doesn’t, you typically cannot assume a specific fish type.
Why some companies don’t name the fish species
Fish oil is often a commodity ingredient. Brands may source oil from multiple catch seasons or suppliers to keep supply steady and maintain consistent EPA/DHA levels. That can make species-level disclosure difficult or changeable over time.
How to find the fish species for a specific product
Check the product’s Supplement Facts panel, ingredient section, and any lot-specific certificate of analysis (COA) or technical sheet the company provides. If the species is not listed there, the most reliable answer is to contact the manufacturer and ask what species (and sourcing region) the product is made from for the current lot.

No specific product or brand was provided in your question, so I can’t name the fish for “your fish oil” without the label details or the brand/model. If you share the brand name (or paste a photo/text of the Supplement Facts and ingredients), I can tell you whether the fish species is stated.
