The study of water properties, velocity pattern and suspended sediment dynamic distribution was conducted at Sepanggar Bay cage culture area There are seven stations chosen randomly. Sampling work was carried out on month of September, October and November during high tide and low tide. Water properties such as temperature, salinity, dissolves oxygen and pH were measured using YSI (in-situ), water samples were carried out using Water Sampler, whereas current velocity and direction were taken by using Aquadopp. The data of current and total suspended sediment were analyzed by Microsoft Excel software. The result of the research showed that most of the sediment distributed nearby the cage culture area. The furthes distance from the cage culture area, the distribution become lesser. Therefore, average of water properties as temperature, salinity, dissolves oxygen and pH shows that the high and lower average were due to the distance from cage culture and depend on high tide and low tide. The average current velocities for each stations were ranging from 0.05 ms�¹ to 0.8 ms�¹. The higher the current velocity, the higher the concentration and distribution of the suspended sediment transported. However, other factors such as cage culture activities, weather such as monsoon wind and tidal factor could affect the situation and can change the water properties and current velocity.
