Abstract

River Estuary is a mixing place of two mass of water such as the freshwater mass and seawater which is influenced by the physical characteristics of water such as seasons, tide, current, temperature, and salinity. Estuary area is one of the area for the mangrove ecosystem where mangrove ecosystem are habitat from kind of benthic organism, one of the kind is gastropods. Gastropod density on mangrove ecosystem was influenced by the activity which was found in mangrove ecosystem, where, it could be giving an effect of gastropod living cause gastropod tend to live staying with limited moving. The aim of this research was to know mangrove density, community gastropods structure and relation between biota(gastropods) and their habitat (mangrove) in river estuary Batang Village which was conducted on October 2009, using method to determine monitoring station was purposive random sampling technique in order to represent research area and to take data by using square transect method. Based on the result of research, the total of gastropod which were achieved on mangrove ecosystem of river estuary Batang Village 10 species from 7 families. The most species were Syncera brevicula. Density of gastropod at research location gyrate from 32-78 individual/m².The high density of gastropoda were getting in stasiun 1 with the total 78 ind/m², where as the low density of gastropoda were getting in stasiun 3 with the total 32 ind/m². Diversity index were range between 1,21-1,50, uniformity ondex in the research location were range between 0,55-0,81 and Domination index were range between 0,29-0,43 which have meaning that there was no domination spesies in the research location. To mangrove vegetatiom in research location of river estuary Batang Village, generally it were founded 6 species from 3 families where the family Rhizoporaceae were mangrove family which dominated the research location.
