Commercial fishing is the practice of catching fish and other seafood for sale and profit. This industry plays a vital role in providing food for people around the world. Fishermen use various methods, such as trawling and longlining, to catch large quantities of fish like tuna, cod, and shrimp. The fish caught in commercial fishing are often processed and distributed to markets, restaurants, and grocery stores. Sustainable practices are becoming increasingly important to ensure that fish populations remain healthy and that the ocean's ecosystem is protected. Efforts like catch limits and marine protected areas help maintain balance in our oceans.
