SELF-SUFFICIENCY MODEL OF TILAPIA AQUACULTURE INMINALIN, PAMPANGA, PHILIPPINES Authors: Alvin T. Reyes
ABSTRACT
This study was conducted in order to create a self-sufficiency model of tilapia aquaculture in
Minalin, Pampanga, Philippines. The specific objectives of this study include the following: (1) To
dynamically visualize the effects of compounding factors on tilapia production and consumption in
the municipality; (2) To forecast local tilapia sufficiency over a given period of time; and (3) To
identify interventions that would improve tilapia self-sufficiency in the municipality.
The study used secondary data from published researches and from official websites of
government offices in the Philippines. The researcher utilized STELLA Version 9.02in order to
dynamically visualize and communicate the self-sufficiency model of tilapia aquaculture in the
municipality.
Available tilapia for local consumption was negatively affected by increasing population,
change in capita consumption towards fish protein, reduction of available land for tilapia farming,
poor water quality, diseases and extreme weather events. In order to lessen the compounding effects
of these factors, interventions such as technology adoption, management of population growth and
reduction of land conversion rate were deemed effective. The local tilapia sufficiency was prolonged
from 16 years to 19 years because of these interventions. In addition, 50% reduction in land
conversion rate could extend the local sufficiency of tilapia until the 26th year.
