A Fish Cutter primarily focuses on the physical preparation of fish for sale or consumption, involving tasks such as filleting, deboning, and portioning. Their role centers on the skilled handling of fish carcasses to ensure they are ready for retail or culinary purposes. In contrast, a Fishmonger encompasses a broader scope, involving not only cutting and preparing fish but also selling seafood products to customers. Fishmongers interact directly with customers, offering advice on different types of fish, seafood recipes, and sometimes even preparing custom orders according to customer preferences.
