If anchovies had a public relations team, they would probably ask for a rebrand. For many people, the word “anchovy” instantly brings up one very specific image: a tiny, salty strip on pizza that divides the table faster than a family board game. But anchovies are much more than a punchline in the great pizza debate. They are real fish, important ocean players, surprisingly nutritious, and one of the most powerful flavor boosters in the kitchen.
So, what type of fish are anchovies? Anchovies are small, schooling, mostly saltwater fish that belong to the family Engraulidae. They are related to herring and sardines, and they are part of a larger group of fish known as forage fish, meaning they feed many bigger animals in the ocean. In the kitchen, they are often cured, salted, packed in oil, or made into paste, which explains why the anchovy on your Caesar salad tastes much bolder than a freshly caught little fish swimming near the coast.
In short, anchovies are tiny fish with a huge résumé. They help support marine food webs, supply omega-3 fatty acids, add deep umami flavor to food, and somehow manage to be both loved and feared by home cooks. Not bad for a fish that can fit on a cracker.
What Type of Fish Are Anchovies?
Anchovies are small, oily fish from the scientific family Engraulidae, in the order Clupeiformes. That order also includes herring and sardines, which explains why these fish are often compared. They are generally slender, silver-sided fish with a bluish-green or greenish back, a pointed snout, and a relatively large mouth that may extend behind the eye.
Most anchovies live in saltwater, especially in warm or temperate coastal seas. Many species also move into brackish water near river mouths, where freshwater and seawater mix. A few tropical anchovy species live in freshwater, but the anchovies most people know from grocery stores and restaurants are marine fish.
There are more than 100 species of anchovies around the world. Some of the best-known include the European anchovy (Engraulis encrasicolus), the northern anchovy (Engraulis mordax), and the Peruvian anchoveta (Engraulis ringens). Different species are found in different oceans and fisheries, but they share the same general identity: small, fast-growing, schooling fish that feed on plankton and serve as food for larger animals.
Are Anchovies the Same as Sardines?
No, anchovies and sardines are not the same fish, although they are often placed in the same culinary and nutritional conversation. Both are small, oily, schooling fish. Both are rich in nutrients. Both are commonly canned. And both have been unfairly blamed for ruining pizza night at least once.
The main difference is taxonomy. Anchovies belong to the family Engraulidae, while sardines usually refer to several small fish in the herring family, Clupeidae. Sardines are typically larger, have a milder flavor, and are often eaten as whole fillets from a tin. Anchovies are usually smaller and more intensely flavored because they are commonly salt-cured before being packed in oil or used in paste.
Anchovies vs. Sardines: Quick Comparison
- Family: Anchovies are Engraulidae; sardines are usually Clupeidae.
- Flavor: Anchovies are stronger, saltier, and more umami-rich; sardines are milder and meatier.
- Common use: Anchovies are often used as a seasoning ingredient; sardines are often eaten as a main protein.
- Texture: Anchovies are delicate and often dissolve into sauces; sardines are firmer and flakier.
- Size: Anchovies are generally smaller and slimmer than sardines.
Think of sardines as the friendly lunchbox fish and anchovies as the tiny chef whispering, “Add me to the sauce and everyone will ask why it tastes better.”
What Do Anchovies Look Like?
Fresh anchovies are small, slender fish with silvery sides, a darker blue-green back, and a long snout. Northern anchovies, for example, can grow up to about seven inches long, though many are smaller when caught. Their bodies are compressed and streamlined, which helps them move quickly in schools near the ocean surface.
One of the easiest ways to recognize an anchovy is by its mouth. Anchovies have a noticeably large mouth and a pointed snout that gives them a slightly distinctive profile compared with other small fish. In adulthood, some species show a faint silver stripe along the side.
If you have only seen anchovies in a tin, you may be surprised by how different fresh anchovies look. Canned anchovy fillets are usually brownish, reddish, or grayish because of curing, salt, and oil. Fresh anchovies are brighter, shinier, and much more delicate. They look less like a “pizza warning label” and more like the elegant little coastal fish they actually are.
Where Do Anchovies Live?
Anchovies are found in oceans around the world, especially in shallow coastal waters. They prefer warm and temperate seas, where plankton is abundant. Since plankton is their main food source, anchovies often gather in areas where ocean conditions support lots of tiny floating plants and animals.
The northern anchovy lives along the Pacific Coast of North America, from British Columbia down to Baja California and into the Gulf of California. In U.S. waters, northern anchovies are commonly associated with the California Current ecosystem, an ocean region known for productive coastal waters.
The European anchovy is found in parts of the eastern Atlantic, the Mediterranean Sea, and the Black Sea. The Peruvian anchoveta is famous for its enormous populations off the coast of Peru and Chile, where nutrient-rich upwelling waters support one of the world’s most important small-fish fisheries.
What Do Anchovies Eat?
Anchovies feed mainly on plankton. Plankton includes tiny drifting plants, animals, and other microscopic organisms suspended in the water. Anchovies often swim with their mouths open, filtering plankton from the water as they move.
This feeding habit is part of what makes anchovies so important. They convert tiny ocean life into energy that larger animals can eat. In other words, anchovies are middle managers in the marine food chain, except they actually do useful work.
Because they eat low on the food chain, anchovies generally do not accumulate mercury in the same way that large predatory fish can. Bigger fish like swordfish, shark, and some tuna species eat many smaller fish over long lifetimes, which can lead to higher mercury levels. Anchovies are small, short-lived, and plankton-eating, which helps explain why they are commonly listed among lower-mercury seafood choices.
Why Are Anchovies Called Forage Fish?
Anchovies are known as forage fish because many larger animals rely on them as food. Salmon, tuna, cod, seabirds, sea lions, whales, dolphins, and other marine predators may feed on small schooling fish like anchovies, sardines, and herring.
Forage fish play a critical role in ocean ecosystems. They form large schools, sometimes called bait balls, that attract predators from above and below. A school of anchovies may look like a glittering cloud underwater, which is beautiful if you are a diver and extremely convenient if you are a hungry sea lion.
This role also makes anchovy fisheries important to manage carefully. Anchovies are used for human food, bait, fish meal, fish oil, animal feed, and aquaculture feed. When fisheries take too many forage fish, the effects can ripple through the food web. Responsible management helps balance human use with the needs of marine predators.
Are Anchovies Healthy?
Yes, anchovies can be a healthy food choice when eaten in reasonable amounts. They are rich in protein, omega-3 fatty acids, vitamins, and minerals. Because they are small fish low on the food chain, they are also generally considered a lower-mercury seafood option.
Anchovies provide omega-3 fatty acids, including EPA and DHA, which are associated with heart, brain, and overall health. They also contain nutrients such as selenium, niacin, calcium, iron, and phosphorus, depending on the form and preparation. If the bones are included, as they often are in tiny cured fillets, anchovies may contribute small amounts of calcium as well.
However, there is one big nutritional caution: sodium. Canned and jarred anchovies are usually salt-cured, so they can be very high in sodium. That does not make them “bad,” but it does mean a little goes a long way. If you are watching your salt intake, use anchovies as a seasoning rather than a main dish, and consider rinsing salt-packed anchovies before cooking.
Common Nutritional Benefits of Anchovies
- Protein: Supports muscle maintenance and satiety.
- Omega-3 fats: Help support heart and brain health as part of a balanced diet.
- Selenium: Supports antioxidant and thyroid-related functions.
- Iron: Helps the body make hemoglobin and transport oxygen.
- Low mercury profile: Anchovies are commonly considered a lower-mercury fish choice.
Why Do Anchovies Taste So Salty?
The strong taste of anchovies usually comes from the curing process, not from the fish itself. Fresh anchovies are relatively mild, delicate, and slightly oily. The intense salty flavor most people recognize comes from anchovies that have been packed in salt, aged, filleted, and stored in oil.
During curing, anchovies develop a deep savory taste often described as umami. Umami is the mouthwatering flavor found in foods such as Parmesan cheese, soy sauce, mushrooms, miso, and slow-cooked meats. That is why a small amount of anchovy can make a sauce taste richer without making it taste obviously fishy.
When cooked gently in olive oil or butter, anchovy fillets often “melt” into the fat. They disappear visually but leave behind a savory backbone. This is why chefs add anchovies to pasta sauces, salad dressings, roasted vegetables, compound butters, and braises. The anchovy may be tiny, but its flavor has the confidence of a Broadway lead.
How Are Anchovies Used in Cooking?
Anchovies are one of the world’s great secret ingredients. In Mediterranean cooking, they appear in pasta sauces, salads, flatbreads, vegetable dishes, and seafood preparations. In American kitchens, they are most famous for Caesar dressing and pizza, but their usefulness goes much further.
Anchovy fillets can be minced and stirred into vinaigrettes, melted into tomato sauce, mixed into butter, layered on toast, or blended into dips. Anchovy paste is convenient for quick sauces and dressings. Salt-packed anchovies offer deep flavor but usually require rinsing and filleting before use.
Easy Ways to Use Anchovies
- Caesar dressing: Blend anchovies with garlic, lemon, egg yolk or mayo, Parmesan, and olive oil.
- Tomato sauce: Melt one or two fillets into olive oil before adding tomatoes.
- Pasta: Combine anchovies with garlic, chili flakes, parsley, breadcrumbs, and spaghetti.
- Roasted vegetables: Stir anchovy butter into roasted cauliflower, broccoli, or potatoes.
- Toast: Serve anchovy fillets with butter, lemon zest, herbs, or roasted peppers.
- Pizza: Use sparingly with olives, capers, onions, or tomatoes for a bold, briny bite.
If you are nervous about anchovies, start with one fillet in a hot pan with olive oil and garlic. Let it dissolve, then add tomatoes or greens. You may not taste “fish.” You will taste “Why is this suddenly restaurant-level?”
Fresh Anchovies vs. Canned Anchovies
Fresh anchovies and canned anchovies are the same general type of fish, but they behave very differently in the kitchen. Fresh anchovies are delicate, mild, and perishable. They are often fried, marinated, grilled, or preserved soon after being caught. In coastal Mediterranean regions, fresh anchovies may be served simply with lemon, herbs, olive oil, or vinegar.
Canned anchovies are usually cured and packed in oil. They are intensely flavored, salty, and ready to use as a seasoning ingredient. They are also shelf-stable, affordable, and easy to keep in the pantry. This is the form most American home cooks encounter.
Anchovy paste is another option. It is made from ground anchovies, salt, and sometimes oil or other ingredients. It is convenient because you can squeeze out a small amount and stir it into dressings, sauces, or marinades. The downside is that paste can taste slightly less complex than high-quality fillets, but it is extremely practical.
Are Anchovies Sustainable?
Anchovy sustainability depends on the species, fishery, location, and management practices. Many anchovy populations grow quickly and reproduce early, which can make them resilient. However, forage fish populations can also fluctuate dramatically because of ocean conditions, climate patterns, and fishing pressure.
When buying anchovies, look for products from responsibly managed fisheries. Sustainability guides, seafood certification programs, and reputable brands can help. Because anchovies are important food for larger marine animals, sustainable fishing is not only about leaving enough fish for next year’s catch. It is also about leaving enough fish in the water for the ocean’s dinner guests.
Why Are Anchovies So Important in the Ocean?
Anchovies may be small, but their ecological value is enormous. They help move energy from plankton to larger animals. Without forage fish, many predators would struggle to find enough food. This includes commercially important fish, seabirds, and marine mammals.
Their schooling behavior also shapes marine feeding events. When anchovies gather near the surface, birds may dive from above while fish and marine mammals attack from below. These feeding frenzies are dramatic reminders that small fish can drive big ocean moments.
Anchovies are also indicators of ocean change. Their populations may rise and fall with water temperature, currents, plankton availability, and other environmental conditions. Scientists study forage fish like anchovies to better understand marine ecosystems and how they respond to natural and human-caused changes.
Do Anchovies Have Bones?
Yes, anchovies have bones, but they are tiny and soft. In canned or cured anchovy fillets, the bones are usually so small that they are eaten without notice. The curing process softens them further. In fresh anchovies, bones may be removed depending on the preparation, although small fish are sometimes cooked whole.
If you buy salt-packed anchovies, you may need to rinse, split, and remove the backbone before using them. Oil-packed fillets are usually already cleaned and ready to cook or serve. Anchovy paste, of course, requires no bone-related bravery at all.
Are Anchovies Safe to Eat?
For most people, anchovies are safe to eat as part of a balanced diet. They are commonly considered a lower-mercury seafood choice because they are small, short-lived fish that feed low on the food chain. That said, people who are pregnant, breastfeeding, feeding young children, or managing specific health conditions should follow official seafood guidance and personal medical advice.
The bigger everyday concern with cured anchovies is sodium. A small serving can contain a lot of salt, so moderation matters. People with high blood pressure, kidney disease, or sodium restrictions should use anchovies carefully and check labels.
Food allergies are another consideration. Anchovies are fish, so anyone with a fish allergy should avoid them. Also remember that anchovies can hide in foods such as Caesar dressing, Worcestershire-style sauces, tapenade, pasta sauces, and certain prepared appetizers. When in doubt, ask before eating.
What Type of Anchovies Are Used on Pizza?
The anchovies used on pizza are usually salt-cured fillets packed in oil. They are not raw fish. They are preserved, intensely flavored, and ready to eat. Because they are salty and savory, only a small amount is needed.
Pizza anchovies pair well with bold ingredients such as olives, capers, onions, garlic, tomatoes, chili flakes, and fresh herbs. They can be polarizing when scattered heavily over cheese, but used thoughtfully, they add depth and balance. The trick is restraint. Anchovies are not confetti. Do not throw them around like a parade just started.
How to Choose Good Anchovies
Good anchovies should smell pleasantly briny and savory, not harsh or rancid. Oil-packed fillets should look neat and moist, not dry or broken into mush. Jarred anchovies are often easier to inspect than canned ones, but both can be excellent.
For the best flavor, choose anchovies packed in olive oil when possible. Salt-packed anchovies can offer exceptional taste, but they require more preparation. Anchovy paste is useful for convenience, especially when you only need a small amount for dressing or sauce.
Buying Tips
- Choose anchovies in olive oil for richer flavor.
- Use paste for quick weeknight cooking.
- Try salt-packed anchovies if you enjoy traditional ingredients and do not mind prep work.
- Check sodium content if salt intake is a concern.
- Store opened anchovies in the refrigerator, covered with oil, and use them within a reasonable time.
Experience: Learning to Appreciate Anchovies
Many people do not fall in love with anchovies on the first try. In fact, the first anchovy experience is often dramatic. Someone orders a pizza, one brave person says, “Let’s get anchovies,” and suddenly half the table acts as if a sea monster has entered the room. That reaction usually comes from meeting anchovies in their boldest form: whole cured fillets sitting directly on top of melted cheese.
A better way to understand anchovies is to begin with them as an ingredient, not a topping. The first time you melt an anchovy fillet into warm olive oil with garlic, something interesting happens. The fish disappears. It softens, breaks apart, and becomes part of the sauce. Then tomatoes, greens, or pasta enter the pan, and the final dish tastes deeper, rounder, and more satisfying. It does not scream “anchovy.” It quietly improves everything, like a good editor fixing a sentence without demanding applause.
One of the easiest beginner experiences is anchovy pasta. Warm olive oil in a skillet, add sliced garlic, a pinch of red pepper flakes, and one or two anchovy fillets. Stir until the anchovies dissolve, then add cooked spaghetti and a splash of pasta water. Finish with lemon zest, parsley, and toasted breadcrumbs. The result is savory, bright, and inexpensive. It tastes like something from a small coastal restaurant, even if you are eating it while standing over the sink in sweatpants. No judgment; some of the world’s finest meals are eaten that way.
Another excellent anchovy lesson is Caesar dressing. Many bottled Caesar dressings taste creamy but flat. Add real anchovy, lemon juice, garlic, Parmesan, black pepper, and olive oil, and suddenly the dressing has character. The anchovy does not dominate; it supports. It gives the dressing that classic savory edge that makes romaine lettuce feel like it got promoted.
Anchovies also teach an important cooking principle: strong ingredients are not always meant to be used in large amounts. Vanilla extract is powerful, but nobody drinks it by the glass. Chili flakes are useful, but a full cup would be a culinary emergency. Anchovies work the same way. Used with care, they bring balance, salt, savoriness, and complexity. Used carelessly, they can overwhelm a dish and make your kitchen smell like low tide wrote a memoir.
For people who think they hate anchovies, the best approach is gradual. Start with anchovy paste in a salad dressing. Then try one fillet melted into tomato sauce. Later, add chopped anchovies to roasted broccoli, white beans, or buttered toast with lemon. Eventually, you may discover that the flavor you feared is actually the flavor you have enjoyed for years in Caesar salads, restaurant pasta, and savory sauces.
The experience of eating anchovies also connects food to geography and tradition. In Mediterranean cuisines, small preserved fish are practical, flavorful, and deeply rooted in coastal life. Before refrigeration, curing fish with salt helped preserve protein and capture the taste of the sea. Today, a small jar of anchovies in the refrigerator continues that tradition in modern form. It is humble, efficient, and quietly brilliant.
So, what type of fish are anchovies in everyday life? They are the tiny fish that teach big lessons: small ingredients can matter, strong flavors can be elegant, and the ocean’s most overlooked creatures often do more work than the glamorous ones. Anchovies may never win a popularity contest against salmon or shrimp, but in the kitchen and the ecosystem, they are absolute heavyweights in a featherweight body.
Conclusion
Anchovies are small, oily, mostly saltwater fish in the family Engraulidae. They are related to herring and sardines, but they have their own identity, biology, flavor, and culinary purpose. As forage fish, they feed on plankton and help support larger fish, seabirds, and marine mammals. As food, they offer protein, omega-3 fatty acids, minerals, and one of the most concentrated sources of savory umami flavor available in a tiny tin.
The next time someone asks, “What type of fish are anchovies?” you can confidently answer: they are small schooling marine fish, important forage species, nutrient-rich seafood, and the secret weapon behind many great sauces, dressings, and pasta dishes. They may be tiny, but they are not minor characters. Anchovies are proof that in nature and in cooking, size is not the same thing as importance.
