Modeling and Simulation of the Rice-Azolla-Crab Mutualistic System

Abstract:

This study modeled and simulated the rice-azolla-crab (R-A-C) mutualistic system based on experiments in rice field. The results demonstrated that: mutualism between rice and azolla happened at low density of azolla but competition happened at high density of azolla; The interaction between rice and crab changed from positive to negative as the density of crab increased; By selecting proper initial values of azolla and crab, mutualism could exceed competition; The economic benefits of rice and crab could be increased by increasing mutualism or positive interaction between rice and crab during the rice’s growth.
