Anchoa mitchilli (Linnaeus, 1758) |
|
Anchoa mitchilli is a species of fish in the family Engraulidae, the anchovies. Its common names include bay anchovy and common anchovy. It is native to the western Atlantic Ocean and Gulf of Mexico. It is one of the most common fish species along the coastlines of the western Atlantic.
The bay anchovy is somewhat variable in appearance. It is a small, slender, schooling fish with a greenish body and a silvery stripe. It is characterized by its very long jaw, silvery belly, lateral stripe, and single dorsal fin. The dorsal fin is located directly above the anal fin origin. The adult male is generally about 6 centimeters long, with a maximum length of 10 to 11 centimeters. It has 14 to 16 rays in its dorsal fin, 24 to 30 in its anal fin, and 11 to 12 in the pectoral. It may live more than three years.
The bay anchovy is similar to other species in the genus Anchoa which occur in the same regions. The broad-striped anchovy is similar in appearance but grows to a larger size, up to 15 centimeters. The Cuban anchovy has its anal fin set farther back on the body.
This species is distributed in the Atlantic Ocean and Gulf of Mexico along the eastern coasts of North America from Maine to Yucatán. It does not occur in the West Indies. It is well-known in the Chesapeake Bay, where it is the most abundant fish.
It occurs in a wide range of water temperatures and salinities, including some hypersaline environments. It does not tolerate low-oxygen waters and easily asphyxiates when deprived of oxygen.
This fish spends most of its time cruising the water column. It can also be found over bare substrates at the ocean floor and in tide pools and surf zones. It can live in muddy, brackish waters. It rarely enters waters deeper than 25 meters.
This fish feeds on zooplankton, including copepods, mysids, and crab larvae.
