A system dynamics model for analysing the eco-aquaculture system of integrated aquaculture park in Malaysia with policy recommendations

The sustainability of aquaculture industry strongly depends on numerous factors such as environment, ecology, economics, industry, human behaviour, policy and many others. The interdependence and balance of these factors is called as eco-aquaculture. However, eco-aquaculture field has not been widely studied, especially in Malaysia. Therefore, to enhance the sustainable development capacity of an eco-aquaculture system, the integrated simulation and analysis of the material-energy flow processes and the trends of process generating the ecological and economic positive–negative effects should be addressed. Thus, the objectives of this study are firstly to develop a system dynamics model of the eco-aquaculture system named ‘SD-AQEP’ to simulate quantitatively flow in the local iSHARP aquaculture industry; secondly, to analyse the integrated effects of the ecological economy, identify the defects and finally to make recommendations to improve the system performance. We build a system dynamics model of a Malaysian eco-aquaculture system (SD-AQEP) to quantify its integrated material and energy flows, identify systemic defects and recommend improvements in its performance. The systems is also able to scientifically diagnose the potential shortcomings and defects in the system, provide the basic improvement policies as well as check the effectiveness of the improvement policies. Hence, this system has the potential to reveal the internal structures in the complex system with ecosystem and other systems such as economy, environment and human activity.
