Santi Sungthong (Eastern Marine Fisheries Development Center, Rayong (Thailand))
Surveys were carried out to evaluate the effectiveness and durability of various type artificial reefs installed off Rayong Province by means of analyses of catches by hook hand line and trap fisheries, diving surveys and echo sounder survey during 1978-1990. The structure of the artificial reefs seemed to strongly affect to the behavior of all kinds of fish aggregated in and around the artificial reefs. Concrete cubic modules were more durable than those made of used tyres, concrete tanks and concrete pipes. The artificial reefs aggregated more fish when it was constructed in larger number of modules and when it was installed in deeper place.
