This research was carried out to analyze the environmental carrying capacity of brackishwater fishponds. The research had been conducted in Gresik, East Java by using the survey method and collecting secondary data from the other researches and related institutions. In this research, three approaches used for analyzing the environmental carrying capacity of the brackishwater fishponds zone, ie.: regression analysis, quantitative method for water availability and weighted methods for land suitability grade. The result showed that utilization of coastal land for the brackishwater fishponds surpassed to its environmental carrying capacity. This phenomenon had once showed in 1999 that maximum production of brackishwater ponds of 12 134.4 tons occupied 10 943.5 ha land areas. By using regression analysis, land area suggested for aquaculture is 9 378.89 ha. By using water quantity method, the land areas suggested for traditional, semi-intensive and intensive cultures are 9 413.49 ha, 1 647.36 ha and 941.35 ha, respectively. The third approach suggested that the land which can be used for milkfish (Chanos chanos) culture is 9 882.89 ha and for shrimp culture is 9 457.28 ha.
