dc.description.abstractA study on the determination of biofoulers settlement on different types of substrates and environment conditions have been conducted at Pulau Betong, Penang. A total of six biofoulers have been recorded. The biofoulers consist of barnacles, tubeworms, oyster spat, bryozoans, snails and sea urchins. The highest biomass of biofoulers settlement on oyster shells were at 0.5 m and 1.0 m depths at both shaded and unshaded area. Water turbidity and temperature were found to be affecting the settlement of the biofoulers on the shells. The biomass of barnacles showed the highest among the rest of the biofoulers when using plastic trays as collectors. At the unshaded area, most of the biofoulers tend to settle at 2 m depth on the plastic trays while at the shaded area, the biofoulers tend to settle at 1 m depth on the plastic trays. Water temperature was found to be the main factor affecting the settlement of biofoulers on plastic trays. The top surface of asbestos sheets has the highest settlement of oyster spat compared to the bottom surface of the asbestos sheet at both shaded and unshaded areas using asbestos sheets. The settlement of oyster spat was higher at the shaded area compared to the settlement of oyster spat at the unshaded area. The settlement of oyster spat on the asbestos sheets was affected slightly by salinity and chlorophyll-a. Meanwhile ammonia concentration showed strong influence on the settlement of the oyster spats on the asbestos sheets.en_US
