The study was done <strong>at</strong> Pulau Payar's artificial reef sites 06.06"N and 100.04°E (Figure I). All <strong>the</strong>artificial reefs were loc<strong>at</strong>ed on <strong>the</strong> eastern side <strong>ofPulau</strong> Payar and <strong>the</strong> south <strong>ofPulau</strong> Kaca. The depthof<strong>the</strong> artificial reefs were between 15 - 30 m. Visual observ<strong>at</strong>ions were done <strong>at</strong> 17-25 metres so as togive each artificial reef <strong>the</strong> same depth tre<strong>at</strong>ment. Observ<strong>at</strong>ion of <strong>the</strong> artificial reefs was undertakenduring <strong>the</strong> neap tide when <strong>the</strong>re was less w<strong>at</strong>er movement, and <strong>the</strong> w<strong>at</strong>er is usually calmer.6.07406.0720;.6.07006.06806.06606.06406.0620Fig. 1: <strong>Artificial</strong> reef loc<strong>at</strong>ion aroung Pulau Payar mapped usingRox-Ann.

Observ<strong>at</strong>ions were also made using underw<strong>at</strong>ervideo filming as a backup.Table 1: <strong>Artificial</strong> reefs loc<strong>at</strong>ion and depth around Pulau PayarNo Type Loc<strong>at</strong>ion Mean depth (m)1 N<strong>at</strong>ural reef 100.041
