WHAT IS AN ANCHOVY?
WHAT IS AN ANCHOVY? Anchovies are small, common saltwaterforage fish in the family Engraulidae that are used as human food and fish bait. There are 144 species in 17 genera found in the Atlantic, Indian, and Pacific Oceans and specially in Persian gulf qeshm island iran. Anchovies are usually classified as an oily fish. They are small, green fish with blue reflections due to a silver longitudinal stripe that runs from the base of the caudal fin. They range from 2 centimetres (0.79 in) to 40 centimetres (16 in) in adult length, and the body shape is variable, with slenderer fish in northern populations.
A traditional method of processing and preserving anchovies is to gut and salt them in brine, allow them to mature, and then pack them in oil or salt. This results in the characteristic strong flavor associated with anchovies, and their flesh turns deep grey. Anchovies pickled in vinegar, as with Spanish boquerones en vinagre, are milder, and the flesh retains a white color. For domestic use, anchovy fillets are sometimes packed in oil or salt in small tins or jars, sometimes rolled around capers. Anchovy paste is also available, as is anchovy essence.
They are used in small quantities to flavor many dishes. Because of the strong flavor of anchovies, they are also an ingredient in several sauces, including Worcestershire sauce, remoulade and many fish sauces, and in some versions of Café de Paris butter. Anchovies are a popular pizza topping in some places. In Roman times, anchovies were the base for the fermented fish sauce garum. Garum had a sufficiently long shelf life for long-distance commerce, and was produced in industrial quantities. Anchovies were also eaten raw as an aphrodisiac.
Additionally, fishermen use anchovies as fish bait for larger fish, such as tuna and sea bass.
