Tinned sardines are one of the most widely consumed and culturally significant canned fish products around the world. Though marketed under a single name, “sardines” actually refers to a range of small, oily fish from the herring family, and the specifics can vary depending on the region, the fish species, and the processing method. Here's a deep dive into sardines in the context of tinned fish:
What Are “Sardines”?
In the canned fish industry, “sardines” is a commercial term rather than a strict biological classification. Generally, any small, silvery, oily fish that is processed and canned whole can be labeled as sardines. These are typically juvenile or small adult specimens from several different species.
Common Species Marketed as Sardines:
- European Pilchard (Sardina pilchardus)
- The "true" sardine, native to the northeast Atlantic and Mediterranean.
- Common in European products (e.g., Portugal, Spain, France).
- Pacific Sardine (Sardinops sagax)
- Found along the Pacific coasts of North and South America, Australia, and Japan.
- Prominent in products from the USA, Mexico, Japan, and Chile.
- Indian Oil Sardine (Sardinella longiceps)
- Abundant in the Indian Ocean, especially around India and Sri Lanka.
- Important for regional markets and export.
- Southern African Pilchard (Sardinops ocellatus)
- Found off the coasts of Namibia and South Africa.
- Canned locally and exported, particularly to Europe and Asia.
- Brisling or Sprat (Sprattus sprattus)
- A small herring used in Scandinavian and Baltic canned products.
- Sometimes labeled as “brisling sardines” (especially in Norway).
- Round Sardinella (Sardinella aurita)
- Found in the Atlantic and Mediterranean; used in African and Middle Eastern exports.
Global Sources of Tinned Sardines
Major sardine-producing countries include:
- Portugal: Renowned for high-quality sardines packed in olive oil, tomato sauce, or even gourmet flavorings (e.g., piri-piri). They mostly use Sardina pilchardus.
- Spain: A major producer, both for domestic consumption and export. Known for artisan and industrial-scale production.
- Morocco: One of the world’s largest exporters of canned sardines, especially to Europe and the Middle East. Utilizes Atlantic species like Sardinella aurita.
- France: Particularly Brittany, with brands like La Belle-Iloise; often emphasizes artisanal processing.
- Norway: Famous for canned brisling sardines, often smoked and packed in mustard or other sauces.
- Thailand & Philippines: Large-scale processors using regional sardine species for domestic and export markets, often in tomato-based sauces.
- India: Major source of Sardinella longiceps; canned products are often sold domestically or in nearby markets.
- USA (Pacific Northwest): Home to Sardinops sagax; sardine fisheries have fluctuated greatly over the years.
- Chile & Peru: Industrial producers of Sardinops sagax, much of which is also turned into fishmeal, but some goes into canning.
Processing & Packaging
Tinned sardines are typically:
- Gutted and cooked (steamed, boiled, or fried)
- Packed in oil (olive, sunflower, soybean), sauces (mustard, tomato, chili, curry), or brine
- Sterilized by pressure-cooking in the can
Whole sardines (with bones and skin) are common, but some versions remove heads or tails. In high-end products, the fish are often hand-packed.
Nutritional Profile
- High in omega-3 fatty acids, calcium (from the edible bones), vitamin D, and protein.
- Shelf-stable and compact, making them ideal for storage and travel.
- Often part of Mediterranean and low-carb diets.
Market Trends & Sustainability
- Growing popularity of gourmet and artisanal sardines, especially in Europe and the U.S.
- Concerns about overfishing, especially in certain regions (e.g., Pacific sardines in the U.S.).
- MSC (Marine Stewardship Council) certification and other sustainability labels are now common on premium tins.
Global Sardine Species Used in Canned Products
| Species | Primary Regions of Origin | Notable Characteristics | Typical Markets |

| Sardinella aurita (Round Sardinella) | Atlantic Ocean, Mediterranean, West Africa | Common in African and Middle Eastern exports; utilized in various canned preparations. | West Africa, Middle East, Europe |
| Sprattus sprattus (Brisling or Sprat) | Scandinavian and Baltic regions (e.g., Norway, Denmark) | Small size; delicate flavor; often smoked; marketed as "brisling sardines" in premium products. | Northern Europe, North America |
| Sardinella gibbosa (Goldstripe Sardinella) | Southeast Asia (e.g., Thailand, Philippines, Indonesia) | Used extensively in regional canning industries; often packed in tomato-based sauces. | Southeast Asia, Middle East, Africa |
| Sardinops ocellatus (Southern African Pilchard) | Coasts of Namibia and South Africa | Similar to Sardinops sagax; significant for both local consumption and export markets. | Southern Africa, Europe, Asia |

Why Do Some "Sardines" Contain Herring?
1. Regulatory Flexibility
In many countries, especially in North America and Europe, food labeling laws allow small members of the herring family (Clupeidae) to be marketed as sardines, regardless of their precise species.
- For example, in the United States, the FDA defines “sardines” broadly to include multiple genera and species, including Clupea harengus (Atlantic herring).
- In Canada, the term “sardine” can be applied to fish of several species as long as the fish is canned whole or in parts and fits certain size and style criteria.
2. Marketing & Consumer Expectations
- The word “sardine” is familiar and attractive to consumers. In contrast, “canned herring” might conjure a different image or expectation — more like pickled herring or kippers.
- Since small herring and young sprats look and taste very similar to traditional sardines when canned, companies often label them as sardines to fit consumer expectations.
Common Substitutes for True Sardines
Here are examples of other fish often labeled as “sardines”:
| Labeled As | Actual Fish | Scientific Name | Details |
|---|---|---|---|
| Sardines | Atlantic Herring | Clupea harengus | Larger species, usually used when small or juvenile; common in Canadian and Baltic products |
| Brisling Sardines | Sprat | Sprattus sprattus | Smaller, delicate fish from the Baltic/North Sea; high-end Norwegian products |
| Sardines | Round or Goldstripe Sardinella | Sardinella aurita, S. gibbosa | Used in African and Southeast Asian products |
How to Tell What You're Getting
Check the ingredient list or scientific name on the tin:
- Many quality brands (especially in the EU) will list the species used, such as:
- "Sardina pilchardus"
- "Clupea harengus"
- "Sprattus sprattus"
- If it just says “sardines” generically, it may be one of the permitted substitutes.
Taste and Texture Differences
- True sardines (S. pilchardus): Meaty, firm, more pronounced flavor
- Herring (C. harengus): Slightly softer, milder, oilier; may taste richer or smokier if processed differently
- Sprats (S. sprattus): Tender and delicate, great in lightly smoked or mustard-packed styles
Bottom Line
If you're seeking a specific taste or culinary experience, it’s worth checking the species name. But nutritionally and culinarily, small herring, sprats, and sardines are all very similar, and can often be used interchangeably.
