Why do commercial fishermen catch sharks?

Sharks have meat that is high in protein and low in fat, making it a popular choice for human consumption. Some shark species, such as the blacktip, dusky, and mako, are prized for their meat, which can be sold fresh, smoked, or dried. Shark fins are also highly valued in some cultures, particularly in Asia, where they are used to make shark fin soup.

2. Shark Liver Oil:

The livers of sharks are rich in squalene, a hydrocarbon that is used in the production of cosmetics, pharmaceuticals, and dietary supplements. Squalene is a natural moisturizer and antioxidant, making it a valuable ingredient in skincare products and anti-aging treatments.

3. Shark Cartilage:

Shark cartilage is a popular ingredient in dietary supplements marketed for its potential health benefits. It contains compounds that are believed to have anti-inflammatory and anti-cancer properties, although scientific evidence supporting these claims is limited.

4. Shark Teeth and Skin:

Shark teeth and skin are sometimes sold as souvenirs or decorative items. Shark teeth can be used in jewelry and other accessories, while shark skin is sometimes used in the production of leather goods.

It's important to note that commercial fishing for sharks is a controversial issue, as some shark species are threatened due to overfishing and habitat loss. Many conservation efforts are underway to protect shark populations and ensure sustainable fishing practices.
