Crustacean fishing involves catching marine animals with a hard shell, such as crabs, lobsters, and shrimp. Fishermen use various methods, including traps, nets, and pots, to capture these creatures. The fishing can take place in oceans, rivers, and coastal areas, depending on the species being targeted. Sustainable practices are important in crustacean fishing to prevent overfishing and protect marine ecosystems. Regulations often dictate the size and quantity of crustaceans that can be harvested, ensuring that populations remain healthy. This helps maintain the balance of marine life and supports the livelihoods of those who depend on fishing for their income.
