A fishmonger is a person or business that sells fish and seafood. They typically work in markets or specialized shops, where they prepare and display various types of fish, shellfish, and other marine products. Fishmongers often have knowledge about different species, their freshness, and the best ways to prepare them for cooking. In addition to selling fish, fishmongers may also provide services like filleting, cleaning, and packaging seafood for customers. They play an important role in the seafood supply chain, connecting fishermen and consumers. Many fishmongers prioritize sustainability, sourcing their products from responsible fisheries and promoting eco-friendly practices.
