Conclusion
Many studies have already shown that without sound management of water quality, feed, and seed input the shelf-life of a shrimp farm could be only five years. Many efforts (closed system, zero water exchange, biological filtration etc.) are currently underway to improve the sustainability of shrimp farming in Thailand and other countries. However, until sustainability is achieved, it is obvious that countries will continue to face the issue of farm abandonment. Thus it is worthwhile to have some alternatives in store for the potential abandonment of shrimp farms. From the present study, the integrated mollusk-shrimp-fish farm can be recommended as having the greatest commercial potential for the reclamation of abandoned shrimp farms. Other important issues to be taken into account are coastal processes, the impact of previous land-use changes, local and national needs as well as ongoing government policy and strategy.
