Abstract:
A study on the macrobenthos distributionand diversity was conducted at Teluk
Kalung coastal water. A total number of 15 stations had been plotted in offshore area
of Teluk Kalung. The macrobenthos samples were collected by using Smith McIntyre
grab. Macrobenthos then were been preserved in 10 % formalin and been brought to
laboratory for further analysis. Highest total of macrobenthos density was at Station 7
(1155.87 ± 854.2 ind/ m2). Station 13 with (90.68 ± 100.17 ind/m2
) had the lowest
value for total density of macrobenthos. The dominant phylum included phylum
Annelida, Arthropoda, and Mollusca. Class Polychaeta under Phylum Annelida
showed high density at all station except station 15 and 5. Phylum Nematode had the
lowest density. At about 287 different organisms collected and 66 were been
identified until species level. The diversity index (H') showed range between 0.98 ±
1.19 to 1.68 ± 1.78 and evenness index (J') between 0.23 ± 0.28 to 0.39 ± 0.42
respectively. The Bray-Curtis similarity indicates that there was 4 group of
macrobenthos at similarity at 70%. The group shared the similar pattern of
distribution. Geographical distribution was used as one of the criteria to determine
the nativeness of a species. From 66 species level identified, only 11 species was
possible to be known as non-native.
