90% of sharks disappear due to hunting

90% of large predatory fish, such as sharks, have been lost by large-scale industrial fishing vessels. According to environmental protection organizations, without effective measures, sharks are difficult to survive through the first half of the 21st century. Hunting for sharks as food, medicine or souvenirs in the world is increasing, leading to a number of sharks that are severely depleted, potentially leading to the destruction of marine animals. this rare.

According to the World Wildlife Fund (WWF) Global Program in a recent message, scientists discovered that 90% of large predatory fish, such as sharks, have disappeared. , removed from the oceans by large-scale industrial fishing vessels.

Destructive and wild fishing activities (such as taking shark fins by cutting fins and throwing away the remains of fish to the sea) are pushing some sharks to the brink of extinction.

Scientists believe that, contrary to popular belief, shark fins have very little nutritional value and may even be harmful to health for a long time because of large amounts of mercury in fish fins.

Some populations, including tiger shark and bull shark, have been reduced to 90%. Other less threatened species such as spiny dogfish and salmon shark (porbeagle) caught for meat and fish oil (mainly consumed in Europe) are also on the decline.

Sharks have survived well before the dinosaurs appeared, and proved to be highly viable. But with the current trend of exploitation and the growing demand for meat and shark products, they will have to ask for help to survive the first half of the 21st century.

Weak exploitation management is a major threat to sharks and marine life in general. Three-quarters of global commercial fish stocks have been overexploited and their catches reach their limit of recovery.
