EP 01 123 REPORT OF ENVIRONMENTAL SURVEY STUDIES ON ARTIFICIAL REEFS AT CHUMPORN PROVINCE, THAILAND. Dr. Yuttana Theparoonrat SEAFDEC/TD TD in collaboration with ASEAN and SEAFDEC member countries conducted Resources Enhancement project in Chumporn province, Thailand as a case study. This project is designed to integrated installation of artificial habitats in inshore waters with careful pre- assessment of environmental and socio- economic impact. Department of Fisheries, Thailand conducted an installation of artificial reefs at Chumporn province on March – April 2004. Two group of cubic shape concrete type, 1.5x1.5x1.5m, total 1750 pieces, are set on the project area number 46-16-07 and 46-16-08 (Fig.1). The artificial reefs settle at 12m depth with area cover is 2 km2. Figure 2. Layout of two group of Artificial Reefs set at project site at Chumporn Province, Thailand Figure 1.
