My country is vast in size and stretches across the tropical, subtropical, temperate and frigid temperate regions and possesses four major seas of the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea. The coastline is 18,000km long, with more than 6,500 islands and about 150 million hectares of continental shelf within a depth of 200m. There are over 1.3 million hectares of shallow beach that can be farmed along the coast. The coastal climate in our country is warm and moist. There are numerous rivers into the sea that bring in a large amount of organic matter. Therefore, there are abundant seawater nutrients and abundant plankton in coastal areas. Sediment is the main sediment in the coastal zone and there are many rocky reefs in some areas. In the fish, shrimp, shellfish, algae multiply growth. Our offshore farming has a long history, especially fishermen and farmers along the coasts of Guangdong, Fujian and Zhejiang provinces
