PHILMINAQ - MITIGATING IMPACT FROM AQUACULTURE IN THE PHILIPPINES

Akvaplan-niva team was the coordinator of the EU funded INCO project in the Philippines to build capacity within the Government and University research departments to mitigate the impact of aquaculture. Akvaplan-niva were partners with the Bureau of Fisheries and Aquatic Resources, Marine Science Institute of the University of the Philippines and the Scottish Association of Marine Science. More details about the project can be found at www.philminaq.eu


:: CAPACITY BUILDING


The project built capacity within the Central and Local Government departments involved with the planning, management and control of aquaculture development.


:: GIS DATABASE


A GIS based aquaculture database was being developed for aquaculture to facilitate the identification of underused and overused aquatic resources and planning and zoning of aquaculture development


:: GUIDELINES FOR LOCAL GOVERNMENT


A set of best practice guidelines were prepared for the Local Government Units (LGU) outlining the laws and regulations for aquaculture, the agencies responsible for planning, management, monitoring and control of aquaculture.


:: INTERAGENCY COOPERATION


The project facilitated interagency cooperation for the management of aquaculture between the 3 main government agencies. A draft Joint Administrative order was prepared covering their scope, jurisdiction and responsibilities.


:: PREDICTIVE MODELLING


Two models were developed during the project. A hydrodynamic model for assessing current flushing and residence time and a depostional model "Tropomod" for predicting deposition of nutrients under the cages and estimation of carrying capacity.


Important aspects:

  1. How severe is the impact - what is the maximum impact underneath cages?
  2. How far to the boundary of the impact? (Scotland = Allowable Zone of Effect)
  3. How can husbandry practices be optimised to use the zone most productively?
  4. 4.What is the safe sustainable carrying capacity of the zone.



:: MONITORING IMPACT


Three levels of monitoring survey were developed ranging from a full scientific baseline survey to survey undertaken by a farmer or LGU. Cost effective monitoring equipment was developed and Government staff, researchers and stakeholders trained in collecting and analysing the data.


:: CATEGORIES OF SURVEYS


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.

Categories of surveys

Category 1.  low cost simple survey that can be undertaken by local Government or larger farmer
Category 2.  Medium level survey that requires some dedicated equipment that can be undertaken by
                    Government regional offices, Protected Area Management, IFARMCs, Aquaculture.
                    parks and other aquaculture management organisations.
Category 3. Comprehensive survey (baseline survey) to be undertaken by Government research
                    Institutes or similar, scientists for EIA, baseline survey or detailed impact studies.
