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.

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.

Biology and ecology

This fish feeds on zooplankton, including copepods, mysids, and crab larvae.

It is in turn an important prey item for a variety of larger fish, including weakfish (Cynoscion regalis), striped bass (Morone saxatilis), chain pickerel (Esox niger), and bluefish (Pomatomus saltatrix). Birds such as royal terns (Thalasseus maximus) and Sandwich terns (T. sandvicensis) feed on it.

This species is an important link in the food web in many ecosystems. It is a major pathway by which zooplankton biomass is converted to the biomass of larger fish.

The bay anchovy is sexually mature when it reaches about 4 centimeters in length. It spawns in the water column in shallow and deeper waters. In the southern part of its range it spawns year-round, and farther north it breeds during the warmer months. A female can spawn 50 times in one season, producing over 1000 eggs each time. Eggs hatch in 24 hours. Larvae mature in about 45 days. Their growth rates are variable and may depend on the availability of food.

Human uses

This species is made into anchovy paste and is used as a bait fish. It is harvested as a rough fish and used for fish oil and fish paste.


This fish is not of conservation concern. It has an extensive range, a large and stable population made up of many subpopulations, and no major threats.
