Sardines vs. Sardinella: Are All Canned Sardines Really the Same?
What if two tins of “sardines” contain different fish? They might look alike on a supermarket shelf, but the species inside can be different. That does not automatically make one tin better or worse. It does mean the name on the front of the package tells only part of the story.
European sardines have a particularly strong connection with Portugal, from the grilled fish served at summer festivals to the carefully prepared tins of traditional conservas. Around the world, however, a variety of small oily fish may be marketed as sardines or sardine-type products. One group is called Sardinella.
In this guide, we explain what Sardina pilchardus and Sardinella actually are, how food standards distinguish them, why Portuguese sardines are so celebrated, and how to choose a tin with confidence.
View product1. What are European sardines?
The European sardine is scientifically known as Sardina pilchardus. It is a small, oily, schooling fish in the herring family, Clupeidae, found in the northeastern Atlantic Ocean and Mediterranean Sea. It is also sometimes called the European pilchard.
Portugal has a long history of fishing and eating this species. In the warmer months, sardines are grilled over charcoal and served with bread, potatoes or salad. Lisbon's Santos Populares celebrations are especially associated with the smell of grilled sardines filling the streets. Sardines are also central to Portugal’s traditional fish-canning industry.
That heritage makes Sardina pilchardus an especially appealing choice for people who want to experience a classic Portuguese sardine. But a brand name or a tin packed in Portugal does not, by itself, prove which species it contains. Species identification belongs on the product information.
2. What exactly is Sardinella?
Sardinella is a genus of fish, not another scientific name for Sardina pilchardus. Both belong to the Clupeidae family, so they are related. But they occupy separate branches of the scientific classification system.
Different Sardinella species live in different marine regions, many of them in warmer tropical or subtropical waters. Examples include:
- Sardinella aurita — commonly called round sardinella;
- Sardinella maderensis — Madeiran sardinella;
- Sardinella longiceps — Indian oil sardine;
- Sardinella gibbosa — goldstripe sardinella.
These fish are edible and important in fisheries and cuisines around the world. Depending on the species and market, they can be sold fresh, frozen, dried or canned. The fact that a product uses Sardinella does not mean it is fake fish, unsafe to eat or inherently low quality.
3. Sardines vs. Sardinella: a quick comparison
| Feature | European sardine | Sardinella |
|---|---|---|
| Scientific identity | Sardina pilchardus (one species) | Sardinella (a genus with multiple species) |
| Fish family | Clupeidae | Clupeidae |
| Distribution | Northeastern Atlantic and Mediterranean | Varies by species; many live in warmer waters |
| Portuguese food heritage | Strong traditional association | Not the classic European sardine species |
| Can be canned? | Yes | Yes, for various species |
| Automatically better quality? | No | No |
The essential distinction is biological identity, not a universal quality ranking. The name tells you which fish you are buying. The full eating experience also depends on the fish’s condition, the preserving medium and the skill of the processor.
4. Can different species legally be sold as “sardines”?
This is one of the most interesting parts of the story. The international FAO/WHO Codex Alimentarius Standard for Canned Sardines and Sardine-Type Products (CXS 94-1981) distinguishes Sardina pilchardus from several other species that can be used for sardine-type canned products, including Sardinella species.
The Codex standard reserves the unqualified name “sardines” for Sardina pilchardus and provides for qualified names, such as names incorporating the fish’s species or geographical description, for other eligible sardine-type fish. This is a description of the Codex international standard; the precise legal labelling requirements depend on the country and applicable regulations.
For shoppers, the practical lesson is straightforward: read the species and ingredient information instead of judging the contents by a familiar word or attractive packaging alone.
5. Is Sardinella lower quality or less healthy?
No—there is no sound basis for saying all Sardinella is inferior to all European sardines. An excellent tin depends on many factors:
- Freshness and handling: how the fish was treated after catch and before processing;
- Preparation: cleaning, cooking and careful packing;
- Preserving medium: the characteristics of olive oil, other edible oils, tomato sauce or seasonings;
- Quality control: hygienic manufacture, proper sealing and storage;
- Your preferences: the flavour, texture and recipe you personally enjoy.
Both groups may supply protein and marine omega-3 fatty acids. Exact nutritional values vary by species, season, portion, processing and packing liquid. It would therefore be misleading to promise that Sardina pilchardus always has more omega-3 than every Sardinella product.
Anyone choosing sardines for specific nutritional reasons should compare the nutritional labels and reliable data for the individual products. Seafood safety also depends on appropriate processing and storage rather than the genus name alone.
6. Why are Portuguese canned sardines so special?
Portugal is famous not just for the fish itself, but also for the culture surrounding it. Traditional canneries have developed recipes and production know-how over generations. A tin can combine carefully prepared fish with good olive oil, tomato, lemon, spicy seasonings or other flavours.
Brands such as NURI, Minerva, Bom Petisco, Ramirez and José Gourmet show the range of Portuguese canned seafood, from familiar pantry favourites to illustrated gourmet editions. Their products should still be checked individually for the species stated on the packaging rather than assumed to be the same.
The tradition also extends to how people enjoy the fish: on toasted bread, alongside boiled potatoes, in salads, with roasted peppers or straight from the tin. This combination of craftsmanship and food culture is why Portuguese conservas can be much more than a convenience food.

View product7. How to identify the fish in your tin: a five-step checklist
Step 1: Look for the scientific name
If the fish is identified as Sardina pilchardus, it is the European sardine. If it is labelled Sardinella aurita, Sardinella longiceps or another Sardinella name, it belongs to the Sardinella genus. Scientific names remove much of the ambiguity that common names can create.
Step 2: Read the ingredient list
Compare the percentage of fish where supplied, the oil or sauce, salt and seasoning. A fish packed in extra virgin olive oil offers a different recipe from one packed in tomato sauce or another edible oil, but the preserving liquid alone does not establish the quality of the fish.
Step 3: Distinguish fishing origin from packing location
The country where a tin was canned is not automatically where its fish was caught. If origin matters to you, look for fishing-area information or ask the seller or producer for clarification.
Step 4: Consider the producer and process
Transparent product information, reputable manufacturing and handling practices are useful when comparing tins. Pretty packaging is enjoyable, but it cannot replace clear ingredients and species information.
Step 5: Let your taste decide
For a first taste of Portuguese-style canned seafood, try a classic tin in olive oil. Then explore spicy, tomato or lemon recipes. There is no single best tin for everyone; the right choice is one whose flavour and information match what you want.
8. A note about European sardines, petingas and other small fish
Portuguese seafood labels may contain terms unfamiliar to international buyers. For example, petingas is a Portuguese culinary term commonly used for small or young sardines. It is not, by itself, a substitute for verifying the scientific species.
Likewise, names such as “pilchard”, “sardine” and regional variants can overlap in everyday speech. This is why biological classification and accurate product information matter, especially when comparing seafood from different countries.

9. Frequently asked questions
Is Sardinella a real sardine?
Sardinella is a real group of edible fish often included in the broader trade category of sardine-type products. Scientifically, however, it is a different genus from Sardina, which includes the European sardine.
Are Portuguese sardines always Sardina pilchardus?
Not necessarily. Portugal has a strong tradition involving Sardina pilchardus, but a Portuguese brand or place of packing does not guarantee that species in every product.
Can Sardinella be good canned fish?
Yes. Good handling, processing and ingredients can produce high-quality canned seafood from Sardinella species.
Is Sardinella safe to eat?
When it is properly sourced, processed and stored, Sardinella can be safe to eat, like other commercially canned fish. Damaged, leaking or unusually swollen tins should not be consumed, whatever the species.
Are European sardines healthier than Sardinella?
Neither group is universally healthier. Both may provide useful nutrients. To compare nutritional value, use information for the specific species and prepared product.
How do I know I am buying European sardines?
Look for Sardina pilchardus on the species or product-information label. If it is not clear, contact the seller or producer before making assumptions.
Do more expensive tins always contain better fish?
No. Price may reflect ingredients, packaging, production methods or brand positioning. It does not prove species identity or guarantee the flavour you will prefer.
10. The takeaway: know your sardines
Not all fish sold under the broad idea of “sardines” are biologically the same. The European sardine, Sardina pilchardus, holds a distinctive place in Portugal’s culinary history. Sardinella refers to a different group of edible fish with its own uses and traditions.
That difference is worth understanding—but it should invite curiosity, not prejudice. A trustworthy can of fish should tell you what it contains, and a great one should also taste wonderful.
