Introduction to Anchovies
Anchovies belong to the family Engraulidae, which comprises over 140 species of small, oily fish. The term “anchovy” refers to a specific group of fish within this family, primarily the European anchovy (Engraulis encrasicholus) and the Californian anchovy (Engraulis mordax). These fish are found in temperate and tropical waters around the world, including the Mediterranean, the Atlantic, and the Pacific oceans.
Biology and Characteristics
Anchovies are characterized by their small size, typically ranging from 3 to 12 inches (7 to 30 cm) in length, and their slender, elongated bodies. They have a distinctive appearance, with a blue-green back and a silver-white belly. Anchovies are also known for their large mouth and sharp teeth, which they use to feed on small crustaceans, plankton, and algae.
Anchovies are a schooling fish, often gathering in large groups to feed, migrate, and spawn. This behavior helps them to protect themselves from predators and to increase their chances of finding food and suitable habitats. They are also anadromous, meaning they migrate from saltwater to freshwater to breed, although some species are known to spawn in brackish water or even in the open ocean.
Habitat and Distribution
Anchovies can be found in a variety of aquatic environments, including coastal waters, estuaries, and river mouths. They prefer areas with warm or temperate waters, typically between 50°F and 75°F (10°C and 24°C), and high salinity levels, although some species can tolerate brackish or freshwater conditions.
Their distribution is widespread, with different species inhabiting different regions of the world. For example, the European anchovy is found in the Mediterranean Sea and the Atlantic coast of Europe, while the Californian anchovy inhabits the coastal waters of California and the eastern Pacific Ocean.
