ENVIRONMENTAL MONITORING AND MODELLING OF AQUACULTURE|
IN RISK AREAS OF THE PHILIPPINES
This 2-year Norad funded research project investigated the impacts of aquaculture in the Philippines,
to develop predictive models and make recommendations on ways to mitigate impact. The project trained Government
staff in the operation of the monitoring equipment, analysis of data collected and the use of models for predictive
assessment of impact and estimation of safe carrying capacity.
|:: ENVIRONMENTAL MONITORING|
6 baseline environmental and production surveys were undertaken in three areas of the Philippines, Bolinao Bay
an enclosed marine bay, Dagupan, a brackishwater estuary and Taal lake a large freshwater lake. There areas
had suffered fish kills in the past.
|:: ENVIRONMENTAL MONITORING EQUIPMENT|
Government staff were trained in the use of the monitoring equipment, analysis of the results and ways to mitigate
the impact of aquaculture.
The equipment used for collecting the data was:
- An echo sounder with GPS to collect bathymetry of the area
- Current meters to collect current speed and direction
- Drogues for the collection of water dispersion data
- CTDO to collect temperature, turbidity, salinity, oxygen, profile through the water column
- Water quality analysis in the laboratory to analyse chlorophyll, phosphorous, nitrite, ammonia
This equipment was donated to the Government Institute.
|:: MODELLING OF AQUACULTURE IMPACTS|
Hydrodynamic models were developed for zoning of aquaculture areas. A box model was developed and validated
for estimating safe carrying capacity for aquaculture.
