Gerres is a common name for a genus of fish belonging to the family Gerreidae, commonly known as mojarra. These fish are mainly found in shallow coastal waters of tropical and subtropical regions around the world, particularly in the Atlantic, Pacific, and Indian Oceans. The genus Gerres includes various species, such as Gerres cinereus, Gerres macracanthus, and Gerres nigri, among others.
Gerres species are typically small to medium-sized fish, typically measuring between 10 to 30 centimeters in length, with some species growing slightly larger. They are characterized by their elongated and slightly compressed bodies, featuring a silvery to bluish coloration. These fish have a moderately deep and forked tail, along with a slightly pointed snout.
Mojarras are known for their adaptability and can be found in a variety of habitats, including estuaries, lagoons, brackish waters, and even freshwater environments. They are typically benthic fish, feeding on a wide range of small invertebrates, such as crustaceans, worms, and mollusks.
Due to their relatively small size, Gerres species are not commonly targeted in commercial fisheries, although they are occasionally caught for subsistence or local markets. Some species of Gerres are also popular among recreational anglers for their fighting ability and taste.
Overall, Gerres refers to a genus of small to medium-sized coastal fish belonging to the family Gerreidae, characterized by their elongated bodies, silvery coloration, and adaptability to various marine environments.
