Abstract

Background: The magnitude of the mangrove ecosystem can be seen from the number of organisms that live dependent on mangrove ecosystems. As we know that the mangrove ecosystem is where spawning and place foraging range of aquatic biota. Objectives: This study determine the composition and abundance of Crustacea and Polychaeta based Mangrove stands in the village of Bulalo Kwandang District of North Gorontalo regency. The research conducted over four months. The method used is survey method and techniques of data collection was done by using a sample square. The data were analyzed by descriptive quantitative. Results: The crustacea species which consists of 3 family, that is Portunidae, Sesarmidae, Ocypodidae, while the Polychaeta only one family that is Capitellidae family. At station 1 species which have the highest index of abundance that is Sesarma sp. Indv/m2 and 0.189 for species that have the lowest abundance index of 0.023 Indv/m2 Scylla serata. While at the station two species that have the highest abundance index Sesarma sp. of 0.188 Indv/m2 which has an index of abundance and low of Scylla serata the abundance index of 0.020 Indv/m2. The most abundance  species found in the Rhizophora sp stands. Where  species of the least discovered that the stand Avicenia sp.

1. Makrozoobenthos composition consisting of 4 families and 8 species of crustacean which consists of three families that Portunidae, Sesarmidae, Ocypodidae whereas Polychaeta only one family that Capitellidae family.
2. The species that has the highest abundance index Sesarma sp. The families Sesarmidae whereas species that has the lowest abundance index Scylla serata of family Portunidae. The species most commonly found in the stands Rhizopora sp. This is allegedly due to the high content of organic matter derived from the decomposition of leaf litter, twigs and wood on the stand Rhizopora sp.
