Pangasius (Pangasianodon hypophthalmus) (catfish) is a popular food in many countries around the world as well as in Viet Nam. At the same time, Pangasius also brings great economic benefits from the exportation. However, unplanned catfish farming leads to environmental degradation, susceptible to disease and high consumption of water. Modeling is a solution that helps to better control the biological processes in the pond, optimizes feed supply and water use. In this study research data collected, measured and analyzed from experimental catfish ponds in Can Tho, together with comparative data sets from other related studies were used to simulate the nutrition and development processes of fish in the ponds. The mathematic equations of plankton development processes were built and solved by the fourth-order RungeKutta method and coded in the Matlab programming language.
