THE ROLE OF MACROBENTHIC COMMUNITIES AS AN INDICATOR FOR THE FERTILITY OF MANGROVE POND: CASE STUDY AT BLANAKAN, SUBANG, WEST JAVA
Abstract: Macrobenthic in
mangrove ecosystems plays an important role as removal particles from the water
column to the sediments. Ecology indexes of macrobenthic communities were used
in this study as an indicator for the fertility of mangrove pond ecosystems.
The study was carried out at mangrove pond in Blanakan, West Java. Data was
collected from four sampling sites: opened pond (TB), sylvofishery pond (TS),
sedimented pond (TT), and conservation pond (TP). Some ecological indexes such
as Margalef’s Index (R), Shannon-Wiener Index (H’), Pielou Evenness Index (E),
and Simpson Dominance Index (D) were used to analyze macrobenthic communities.
The results showed that infaunal macrobenthic communities were stable at TP
with R: 1.91±0.42, H’: 1.59±0.30, E: 0.74±0.14, and D: 0.29±0.12. They were
unstable at TB with R: 1.63±0.80, H’: 1.36±0.32, E: 0.74±0.06, and D:
0.35±0.07. The macrobenthic communities can be used as indicator for the fertility
of mangrove pond in Blanakan, West Java.
