1, the price level: Indonesia's round crab has a high price. Indonesia's main market is abroad, and the export cost is high, so the price is high. The main market of Hainan round-axis crab is in China, and the transportation cost is low, so the price is low.

2. Is it easy to arrest: Indonesian round crab is easy to arrest. The waters near Indonesia are low in pollution, fast in velocity and clear in water quality. The round-axis crabs like to move at night and usually lurk in rocks or reefs. The body color of the crab is light yellow, and it is easy to find its existence on rocks. However, the water near Hainan is slow and polluted relatively seriously, so it is not easy to find the existence of the crab and to be arrested.
