In North Carolina, the number of Cownose Rays is increasing as many scientists believe this is the result of the decrease in the number of sharks in the area. Due to the increase in Cownose Rays, the number of shells sharply declined, forcing the scallop shell fishery in North Carolina Bay to be forcibly terminated. Let's catch a wonderful white shark and hammerhead shark using a method called "long lining". Long wire is made of monofilament, monofilament is made of monofilament plastic. In international waters, long lining is not illegal, but it is illegal in the US Pacific coast of California, Washington, Oregon.
Since 1997, the increase in shark's fin is mainly due to an increase in demand for shark's fin soup and traditional processed shark's fin, especially in China and its surrounding areas, as well as improvements in fishery technology and market economy. The Shark Expert Group of the International Conservation Union is a shakuhile is common, "Shakuhire transactions that expand rapidly and are largely unregulated are one of the most serious threats to shark populations around the world There is. The worldwide value of shark fin trading is estimated to be between 540 million dollars and 1.2 billion dollars (2007). Shark's fin is one of the most expensive marine products, usually retailed at $ 400 per kilogram. In the United States where fins are forbidden, some buyers consider jim sharks and sunbathing sharks as trophies and pay $ 10,000 to $ 20,000 to the fins.
Demand for shark's fin soup is so great that sharks are in danger in just a few decades. Every year, tens of millions of sharks are being killed by a fin used in shark fin trading. This is the demand for fins far beyond the demand for fin meat and promotes consumption of this unsustainable shark. The fin value is 20 to 250 times that of meat 2. The low reproductive capacity of sharks is in stark contrast to most other fish with high reproductive potential. On the other hand, sharks have few predators bill billions of years ago, and humans have been actively capturing until about thirty years ago.
Sharks are often killed by shark's fin soup. Fishermen will capture live sharks, fins, and then return animals without chicks back into the water. Shark fin includes fins removal with hot metal blades. The resulting immovable sharks will soon suffocate or die by predators. Shark's fin is the main trade in the world's black market. In 2009, the fins sold at about $ 300 / pound. Poachers illegally earn millions of dollars each year. There are few governments implementing laws to protect them. In 2010, Hawaii became the first US state to prohibit the possession, sale, trading or sale of shark fin. From 1996 to 2000, about 38 million sharks die each year from fishing due to sharks.
