A study was conducted to analyse the assemblages of invertebrates that live<br />

associated with fouling slipper oyster, Magallana bilineata with different stations<br />

and relates with intensity of aquaculture activities at Setiu Wetlands. A total of<br />

three sampling sites according to the intensity of aquaculture activities were<br />

selected with three replicates of oyster clumps were collected from each<br />

station. In total, 689 individuals from 11 families of invertebrates were found<br />

at three stations. Density and evenness of the associated organisms was the<br />

highest at Station 1. However, diversity index (H’) was highest for Station 2.<br />

Salinity and pH had significant differences (p< 0.05) between Stations 1 and 2,<br />

and Stations 1 and 3 respectively. There were significant correlation between<br />

diversity of associated organisms with physical parameters and aquaculture<br />

activities. The study revealed the effects of aquaculture activity on fouling<br />

ecology in estuarine ecosystem.<br />
