Engraulis encrasicolus, commonly known as the European Anchovy, is a small, pelagic schooling fish belonging to the family Engraulidae. It is characterized by its slender, elongated body, a prominent snout that extends beyond its lower jaw, and a silvery coloration. This species is of significant ecological and commercial importance, forming large schools in coastal and offshore waters.

Snout
The most distinguishing feature is the pointed snout that clearly projects beyond the lower jaw, covering the mouth.
Mouth
The mouth is large and extends far back, often past the posterior margin of the eye.
Body Shape
Slender, cylindrical body, typically reaching 10-15 cm in length, with a maximum recorded length of about 20 cm.
Coloration
Bluish-green back, silvery sides, and a white belly. A faint silvery stripe may be visible along the flank.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Primarily pelagic, inhabiting coastal waters and continental shelves, typically from the surface down to 100-200 meters, though occasionally found deeper.

- Marine, schooling in open water, often near estuaries and areas of high productivity. Tolerant of a wide range of salinities, occasionally entering brackish waters.
- Areale geografico
- Widespread in the Northeast Atlantic Ocean, including the North Sea, English Channel, and Bay of Biscay; throughout the Mediterranean Sea and Black Sea; and along the coast of Northwest Africa.

Fatti chiave
Schooling Behaviorbehavior
European Anchovies form vast, dense schools, often numbering in the millions, which is a key defense mechanism against predators and facilitates feeding.
Ecological Roleinteresting
They are a crucial forage fish, serving as a primary food source for numerous marine predators including larger fish (tuna, mackerel), seabirds, and marine mammals.
Filter Feedersbehavior
Despite their large mouth, anchovies are primarily filter feeders, consuming plankton (copepods, larval crustaceans, phytoplankton) by swimming with their mouths open.
Reproductive Strategybehavior
They are highly fecund, producing numerous pelagic eggs that drift in the water column, contributing to their rapid population turnover.
Commercial Importanceinteresting
The European Anchovy supports significant commercial fisheries, particularly in the Mediterranean and Bay of Biscay, where it is harvested for human consumption (fresh, canned, salted) and for fishmeal/oil.
Nocturnal Vertical Migrationbehavior
Anchovy schools often exhibit diel vertical migration, moving to deeper waters during the day to avoid visual predators and ascending to shallower waters at night to feed on plankton.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: edible
- Note sul maneggio: No specific handling precautions are required. They are small, non-venomous fish. Care should be taken to avoid damaging their delicate scales if handling for scientific purposes.
Specie simili
Sardine
Sardina pilchardus
Sardines have a shorter snout that does not extend beyond the lower jaw, and their mouth is terminal or slightly superior. They also typically have more prominent scales and a series of dark spots along their flanks (though not always present).
Sprat
Sprattus sprattus
Sprats have a more compressed body, a terminal mouth, and a row of sharp, keeled scales along their belly (scutes) which are absent in anchovies. Their dorsal fin is also positioned further back.
Other Anchovy Species
Various Engraulis spp.
Distinguishing E. encrasicolus from other anchovy species (e.g., E. anchoita, E. mordax) often requires examination of meristic counts (vertebrae, fin rays) and precise geographical location, as morphological differences can be subtle. E. encrasicolus generally has a more elongated body and specific vertebral counts.
