The Bolinao reef system in Santiago Island, Bolinao, Pangasinan, Philippines is classified as a true fringing reef area and dominated by dense sea grass beds and corals. However, anthropogenic disturbances such as milkfish culture have led to the rapid deterioration of its ecosystem and water quality.


Research objective:

To study hydrodynamics and water quality in order to propose management options for milkfish culture in harmony with sustainable resource utilization. The field survey was therefore found essential to quantitatively describe the physical and bio-chemical conditions around Santiago Island.

Overview of the field survey:

The survey utilized various data-logging sensors to measure several hydrodynamic parameters. Hydrodynamic parameters were monitored through bottom fixed deployment and taut-wire moorage system.


We also measured the chemical and biological water quality parameters. These water quality parameters were monitored by water sampling and STD-type sensors.


We established additional weather station at the southeastern side of Lingayen Gulf. With just one weather station established at the extreme northwestern part of Lingayen Gulf, the weather station that was put-up this time will be used to compare the spatial and temporal effect of local wind system prevailing in the area.
