The Atlantic croaker (Micropogonias undulatus) is a species of marine fish in the family Sciaenidae. It is found in the western Atlantic Ocean from Massachusetts to the Gulf of Mexico. The species is known for the distinctive croaking sound it produces, which is generated by vibrating its swim bladder using special muscles.

Description

The Atlantic croaker has a silvery body with a pinkish hue and is characterized by its elongated shape. It typically grows to about 12-20 inches in length and can weigh up to 5 pounds. The fish has a downward-facing mouth and barbels on its chin, which it uses to detect prey in the sediment.

Habitat

Atlantic croakers inhabit coastal waters, estuaries, and bays. They prefer sandy or muddy bottoms where they can forage for food. During the warmer months, they are commonly found in shallow waters, while in the winter, they migrate to deeper offshore waters.

Diet

The diet of the Atlantic croaker consists mainly of benthic invertebrates such as crustaceans, mollusks, and polychaete worms. They use their barbels to sense and locate prey in the substrate.

Reproduction

Atlantic croakers spawn in the fall, with peak spawning occurring from August to October. Females release eggs into the water column, which are then fertilized by males. The eggs hatch into larvae, which are carried by currents into estuarine nursery areas where they grow and develop.

Economic Importance

The Atlantic croaker is an important species for both commercial and recreational fisheries. It is commonly caught using trawls, seines, and hook-and-line gear. The fish is valued for its mild flavor and is often used in dishes such as fish stew and fried fish.

Conservation Status

The Atlantic croaker is currently listed as Least Concern by the International Union for Conservation of Nature (IUCN). However, like many marine species, it faces threats from overfishing, habitat degradation, and pollution.
