A fish market is a place where people can buy fresh, delicious seafood. However, not all fish is easy to cut. In fact, some fish are harder to cut than others. Some of the harder fish to cut include sharks, swordfish, and tuna. These types of fish have tough skin that can be difficult to remove without damaging the meat. Another type of hard fish to cut is salmon. Salmon skin is very thin and can be difficult to slice without tearing it. Additionally, salmon flesh is delicate and easily damaged when being sliced or diced.
