Over the years, there has been a big steady demand for milkfish or bangus in the country. It has also been doing well in the international market with Philippine export of frozen or chilled bangus reaching over 526 metric tons or some P8.5 million annually.

The following gives a good overview of how to manage your own fishponds using a site already developed.

Site selection

Select existing brackishwater fish farms that are fully developed and operational. Former prawn farms can be used for milkfish farming. The site should have:

high tidal range and can hold water at least one meter deep;
good water quality and more or less have constant salinity and temperature throughout the year;
longer dry season, sandy clay loam, silty clay loam; and
access to roads and power supply.
