Merluza (Hake) is a white-fleshed fish belonging to the order Gadiformes and the family Merlucciidae, primarily caught in the Atlantic Ocean, the Mediterranean Sea, and along the coasts of South America. In Japan, it is also called “Hake” and is widely distributed as an imported white-fleshed fish. Its flesh is tender with a mild, delicate flavor, low in fat, and popular as a healthy ingredient. It can be prepared in various ways, including frying, meunière, and simmered dishes, and its minced flesh is also used as a raw material for processed fish products. Compared to cod, it has relatively stable pricing and supply, making it widely utilized in school lunches, the food service industry, and products for mass retailers.
