ABSTRACT

The study was conducted in order to document the tilapia farm practices in Lubao, Pampanga, Philippines. The survey was held from June to August 2014. The profiles of farm practices were projected into digital maps using the ArcGIS Software. A total of 200 tilapia operators from the 44 barangays of Lubao were interviewed for the making of digital maps. The study was able to determine the following information: (1) Most of the tilapia farmers in Lubao were operating a medium-scale fishpond at semi-intensive stocking density. The fishponds were sun dried and limed first before stocking size #22 tilapia fingerlings. Most of the operators were using deep well as water source. The fish were fully fed using commercial feeds and the duration of culture usually lasted for 5 months; (2) Most of the farms experienced fish diseases and fish kills and these were associated to bacteria, fungi and virus. Disease-related problems happened during dry season and fish kill outbreaks were experienced all throughout the year. Factors such as extreme environmental condition, unsafe source of water and poor water quality in ponds contributed to the occurrence of the problems; and (3) The operators were receiving limited technical support from the government or private agencies with respect on the occurrence of fish diseases and fish kills.
