Commercial fish are species that are caught and sold for human consumption or other uses. These fish are typically harvested in large quantities from oceans, rivers, and lakes. Common examples include salmon, tuna, and cod. The fishing industry plays a significant role in the global economy, providing jobs and food for millions of people. Sustainable fishing practices are essential to ensure that fish populations remain healthy and ecosystems are protected. Overfishing can lead to the depletion of certain species, which can disrupt marine life and affect communities that rely on fishing. Regulations and management strategies are often implemented to promote responsible fishing practices.
