A commercial fisherman is a person who catches fish and other seafood for sale rather than for personal consumption. They often work on boats and use various methods, such as nets, traps, or lines, to harvest marine life. The seafood they catch can include species like salmon, tuna, and shrimp, which are sold to markets, restaurants, and grocery stores. Commercial fishing is an important industry that contributes to the economy and provides jobs. Fishermen must follow regulations to ensure sustainable practices and protect fish populations. They often face challenges such as changing weather conditions and fluctuating market prices.
