Delta as one of aquatic environment is a rich area with high productivity due to the accumulation both of nutrient and organic matter derived from the headwaters and sea. Most of the deltas in tropical area that occupied with the tree of mangroves. Such as in several large delta in the tropics that one of them include Delta Wulan, Demak. Several study has shown the result that the ecosystem of mangrove is a high flourish area. Many species of larval fish depends on mangroves as the nursery area. The different condition of mangrove density can affect the abundance and composition of larval fish. The purposes of this research are to determine the abundance and composition of larval fish in the different condition on mangrove density and to determine relation between the abundance of larval fish with different condition of mangrove density. This research were used the case study method. The results of this research on three different station are: high density with total of 3200 trees/Ha and total of the abundance of larval fish are 290 Individual/250 m3consist of 16 families.
