The marketing system analyses were divided into two parts according to types of oyster: small oyster (Saccostrea commercialis) in Eastern regionand large system (Crassostrea belcheri) in Suratthari. The market structures of small and large oysters were oligopolized. Traders of small oyster included agent, collector, wholesaler and retailer while large oyster traders were collector and wholesaler. Collector, wholesaler and retailed preferred buying in-shell small systems. In-shell large oyster were sold directly to the restaurant. About 71.05 and 85.95% of the trades of small and large oysters, respectively, had regular customers. This became a barrier for new sellers to enter into business, in addition to capital. The consumers had to pay high price for shocked fresh small oysters and large oysters for high farm price. With the improvement of marketing system of both small and large oysters, alternative processing for small oysters and new technology with lower cost of production for large oysters, consumer price will be decreased. Thus, domestic demand will be increased due to low price and in term will attract more farmers to go on oyster cultures
