Yellowtail is a common name for several species of fish, primarily referring to the California yellowtail (Seriola lalandi) and the Japanese yellowtail (Seriola quinqueradiata). These fish are known for their streamlined bodies and distinctive yellow stripes along their tails. They are popular in both recreational and commercial fishing due to their size and taste. In culinary contexts, yellowtail is often served as sushi or sashimi, especially in Japanese cuisine. The fish is prized for its rich flavor and firm texture, making it a favorite among seafood lovers. Additionally, yellowtail is a good source of protein and omega-3 fatty acids.
