The Striped Beakfish (Oplegnathus fasciatus) is a species of marine fish belonging to the family Oplegnathidae. It is native to the coastal waters of the northwestern Pacific Ocean, particularly around Japan, Korea, China, and Taiwan. This fish is easily recognized by its distinctive vertical black stripes running along a silver-gray body, giving it a striking appearance.

Typically, Striped Beakfish grow to about 30 to 50 centimeters in length and have a robust, laterally compressed body. Their name derives from their beak-like fused teeth, which they use to feed on hard-shelled prey such as crustaceans, mollusks, and barnacles. This diet contributes to their role as an important predator in their coastal reef habitats.

The Striped Beakfish is commonly found around rocky reefs, kelp forests, and submerged structures, thriving in temperate waters. It is a popular target for both commercial and recreational fisheries due to its firm, white flesh and mild, slightly sweet flavor.

In culinary uses, especially in Japanese cuisine, Striped Beakfish is prized for sashimi and grilling preparations. Its texture is firm yet tender, making it suitable for various cooking methods, including steaming and pan-frying. The fish’s balanced flavor pairs well with simple seasonings, highlighting its natural taste.

Because of its distinctive appearance, moderate size, and culinary appeal, the Striped Beakfish holds both ecological and economic importance in coastal communities throughout its range.
