Economic Importance for Humans: Positive
Humans hunt great white sharks primarily for sport and for body parts. Great white sharks have developed a reputation in the media as being aggressive and ferocious and as a result they have become a highly prized sport fish. A fully intact jaw of a great white shark can be sold for thousands of dollars. Great white sharks are never abundant because they are at the top of their food chain. In areas that contain great white sharks, boaters and dive operators can earn a living from “shark tourism”. This “shark tourism” allows visitors to see great white sharks up close from the safety of a steel cage suspended in the water (Long, 2009). Traded products that come from great white sharks include fins, jaws, teeth and meat, cartilage, and skin for leather. Liver oil is used in medicines, and the carcass can be used for fish-meal and fertilizer.The trade in shark fins is generally on the increase with records from the Food and Agriculture Organization (FAO) of the United Nations indicating that the international fin trade increased significantly between 1980 and 1990. The demand for shark fin escalated further during the 1990s, making it one of the most expensive fishery products. Jaws and teeth are the most valuable great white shark products in trade.
