Illegal fishing refers to the practice of catching fish in violation of laws and regulations set by governments or international bodies. This can include fishing without a license, exceeding catch limits, or using banned methods and equipment. Illegal fishing threatens fish populations and disrupts marine ecosystems, leading to long-term environmental damage. Additionally, illegal fishing often undermines local economies that depend on sustainable fishing practices. It can lead to conflicts between legal fishers and those engaging in illegal activities. Efforts to combat illegal fishing involve increased surveillance, stricter penalties, and international cooperation among countries and organizations like FAO (Food and Agriculture Organization).
