Bonorowo Wetlands 6: 43-58. Mangrove ecosystem has high productivity because it has the ability to a nutrient trap, which supports aquatic biota, especially fish. The purpose of this study was to determine the relationship between mangrove densities with total fish catch, number of fish species, and fish diversity. The data collections were mangrove condition, fish, physical, and chemical parameters. The results showed that mangrove density in Pabean Ilir Village is higher than in Pagirikan village. The highest importance value index of mangroves was Rhizophora mucronata and Avicennia marina. The total number of fish caught in two locations was 1,093 individuals, consisting of 80 species belonging to 38 families. The dominant fish species were Ambassis nalua, Johnius belangerii, Leiognathus equulus, and Platycephalus indicus.
