Abstract

Pulau Baai Port, Bengkulu is an area that being flowed by domestic waste from local residents. Environmental pressure in the waters could affect the level abundance of macrozobenthos. The research objective was to identify species density, relative density, macrozobenthos community index and its relations with physical-chemical watery parameters at Pulai Baai Port. The research procedure included : sediment and macrozobenthos sample collecting from 4 stations, measurement of physical-chemical watery parameters, sediment fraction analysis, macrozobenthos identification and data analysis. The results of the research showed that there were 7 species of macrozobenthos from 3 classes, namely gastropod, bivalve and malacostracan. The results of the sediment fraction analysis showed that station 1 had clayey sand fraction and station 2,3,4 had sandy clay fraction. The epifauna density obtained from station 1 was 24 ind/m2, station 2 and 3 were 29 ind/m2 and station 4 was 17 ind/m2. The highest diversity index value was on station 3. Station 4 had higher domination index value (0,44) rather than other stations. The lowest domination index value was on station 3 (0,24). Based on PCA analysis, there were relations of species density, sediment fraction and water physical-chemical parameters. Station 1 was characterized by sand substrat, station 2 characterized by Scylla, Cerithidea, salinity and temperature, then station 3 characterized by Uca Neritina and Anadara.
