Anchovies are small, silvery schooling fish that play a massive role in both marine ecosystems and global fisheries. Found in oceans around the world, they form huge shoals in coastal waters and feed mainly on plankton. Despite their tiny size, anchovies support countless larger predators, including fish, seabirds, and marine mammals. They are also widely harvested for human food, bait, and fishmeal, making them one of the most economically and ecologically important fish groups on Earth.
1. European Anchovy (Engraulis encrasicolus)
The European anchovy is one of the most well-known anchovy species in the world and is widely harvested for food. It is especially famous in Mediterranean cuisine, where it is used fresh, salted, or canned. This small schooling fish plays an important ecological role by linking plankton to larger marine predators.
Identification

FAQs
What are anchovies mainly used for?
Anchovies are widely used as food, bait, and in the production of fishmeal and fish oil. In many countries, they are eaten fresh, dried, salted, or canned and are valued for their strong flavor and high omega-3 content. They are also essential for feeding farmed fish and livestock.
Are all anchovy species small in size?
Yes, almost all anchovy species are small fish. Most grow between 5 and 20 centimeters long. Their small size allows them to form huge schools, which helps protect them from predators and makes them highly efficient at feeding on plankton.
Where are anchovies commonly found?
Anchovies are found in oceans around the world, especially in coastal and upwelling regions. They are common in the Mediterranean Sea, Atlantic Ocean, Pacific Ocean, and Indian Ocean, usually living near the surface in nutrient-rich waters.
What do anchovies eat in the wild?
Anchovies mainly eat plankton, including tiny crustaceans, algae, and fish larvae. They are filter feeders, swimming with open mouths to trap microscopic food particles, which makes them a vital link between plankton and larger marine animals.
Why are anchovies important to marine ecosystems?
Anchovies play a key ecological role because they transfer energy from plankton to larger predators such as tuna, seabirds, dolphins, and seals. Without anchovies and similar forage fish, many marine food webs would collapse or become unstable.
