Segara Anakan, a brackishwater lagoon located in the west side of Cilacap on the south coast of Java, is becoming shallower and smaller yearly due to siltation. The two distinct shrimp fisheries in the Cilacap areas are the lagoon and the offshore fisheries. Several problems have been hindering the ecological role of Segara Anakan and the surrounding mangroves as a nursery ground for penaeid shrimp; the decreasing water volume due to rapid siltation; the shrinking mangrove areas; the excessive fishing effort and the use of nets with very fine mesh size; and the deteriorating water quality. Thus, there was a need for the research. As observed, one possible consequence of the siltation of the lagoon is the reduction of the size of the nursery ground. Such a condition of the nursery ground will influence the recruitment of adult shrimp from the offshore area and then affect its population size and the magnitude of the catch.
