An economic model that maximizes the total profit of aquaculture farmers is then used for determining the fish land use in order to meet environmental goals. The result shows that the total profit is around $455 million when no regulation is imposed. This number would be decreased by 31%, 43%, 56% and 74% if the annual land subsidence level is controlled at 2.85 c.m., 2.14 c.m., 1.42 c.m. and 0.71 c.m. respectively and the current retired farm land is still leaving unused. However, when the current retired land is used again for production, the profit would be reduced less than unused case under the same regulation. Furthermore, if the government can help the farmers to relocate their fish farms from areas that are more prone to subside than the ones which are less sensitive, the total profit could be higher no matter the regulation is put on the whole area or on each individual farmer. Therefore, when the interaction caused by pumping groundwater among neighborhood farmers is considered, re-locating aquaculture land and re-use the current retired land at the same time could effectively solve the land subsidence problems without losing too much profit.
