Nemipterus

Nemipterus is a genus of fish in the family Nemipteridae, commonly known as threadfin breams. These marine ray-finned fishes are found in the Indo-Pacific region, inhabiting sandy and muddy bottoms of coastal waters and continental shelves. They are demersal, meaning they live and feed on or near the seabed.

The genus Nemipterus is characterized by its relatively small to medium size, typically ranging from 10 to 30 centimeters in length. They possess a slender body, a forked tail fin, and a prominent lateral line. A distinctive feature of many Nemipterus species is the presence of one or more elongated, filamentous rays in the dorsal or anal fins, which gives them their common name. Their coloration varies, but often includes shades of pink, yellow, and silver, with some species exhibiting distinct patterns or spots.

These fish are primarily carnivorous, feeding on small invertebrates such as crustaceans, polychaete worms, and mollusks, as well as small fishes. They play an important role in the benthic ecosystem. Nemipterus species are commercially important in many parts of their range, being a significant component of artisanal and commercial fisheries. They are often consumed fresh, dried, or salted. Several species are readily recognizable, though identification can sometimes be challenging due to similarities among them.
