鲭科, or the mackerel family, consists of various species of fish known for their streamlined bodies and swift swimming abilities. These fish are typically found in both temperate and tropical oceans, often inhabiting open waters. They are characterized by their distinctive coloration, which usually includes a metallic sheen and dark vertical stripes. Mackerel are important both ecologically and economically. They serve as a vital food source for larger predators, such as 海豚 and 鲨鱼, and are also popular among fishermen. Many species within the 鲭科 are harvested for human consumption, making them a significant part of the global seafood industry.
