ABSTRACT

A survey of the potential for seafarming in the Riau Archipelago District was conducted during July 1981. Potential for farming oysters, groupers, rabbitfishes, seaweeds and green mussels was identified in the Riau Islands. Farming of groupers and oysters is recommended for the Anambas Islands. Aquaculture trials proposed to be completed under project GCP/INS/056/CAN are described. Several recommendations for government actions to expand seafarming are included.
