Asia has always been the main area of shark fin trade and production. Hong Kong is at the core of the shark fin trade, but actually the shark fin trade market is distributed all over the world. Due to the wide coverage in the world, the above map can only show that some countries or regions are directly related to the shark fin industry, but cannot list all countries or regions one by one.

流刺網的殺傷力很大，大型流刺網往往由大、中、小網目的三層網子所構成，不論是大魚、小魚都全部落網，會造成生態浩劫。

Gillnetting is a fishing method mainly used to catch migratory fish. The drift gillnet uses a rectangular mesh woven with one or more layers of plastic filaments. Generally, multiple meshes are combined. The upper edge is tied with a plurality of floats made of sponge plastic, and the lower end is equipped with a lead sinker, which is vertically stretched. Opened near the sea level, waiting for fish to swim in and become entangled in nets. Because it moves with the ocean currents and the entangled fish hang on the net like a thorn, it is called a "drift net."

The lethality of drift gillnets is great. Large drift gillnets are often composed of three layers of nets of large, medium and small nets. Both large fish and small fish are caught, which will cause an ecological catastrophe.
