The paper analyses the domestic markets and demand for giant clams in Fiji, Tonga and Western Samoa. For the three countries, historical trends in giant clam marketing are presented. The potential domestic markets for giant clam meat are then considered. The demand by the tourist sector (e g. hotels and restaurant) is found to be very limited in Fiji and almost non-existent in Tonga and Western Samoa. Demand by private consumers may be sufficient to support a very small clam maricultural industry. Consumer's preferences for giant clams are also considered for Fiji.
