Fish boards are specialized tools used in the fishing industry to display and sell fish. They are typically made of wood or plastic and feature a flat surface where fish can be arranged for customers to see. These boards help keep the fish organized and fresh, making it easier for buyers to choose their desired catch. In addition to their practical use, fish boards often showcase the variety of fish available, such as salmon, tuna, and cod. They can be found at local fish markets, grocery stores, and seafood restaurants, playing a crucial role in the presentation and sale of seafood products.
