Oyster Farming

I don't think I've ever eaten an oyster but after reading a passage about oyster farming I am way more interested in the process. For one oyster farming has been around for centuries, in fact in Japan there are accounts of oysters being cultivated before the birth of Christ.

The featured video shows one technique but another is to attach oysters to strings. The article explained how "spat" (little baby oysters) are places on shells or ceramic tile attached to the line. The source of the picture below says oysters are tied to the lines- which causes them to grow faster, have a higher yield as well as reduce costs.
