| Summary: | (This is the pioneer study focused on the community study of marine nematode (until the
species, level) in Sarawak. The surveys on the marine nematode were carried out at 20 sites
along the Sarawak coastal waters. A total of 87 species of marine nematode had been
recorded along the Sarawak coastal waters. Miri Beach had the highest abundance and species
number of marine nematodes followed by Sematan River. Results showed that the abundance
of the marine nematode in the coastal study was significantly different (p-value < 0.05) and
correlated to the four parameters: pH, DO, sand and silt (correlation = 0.311). In the
horizontal study of the nematode in Teluk Awar (Kuching), particle size fractions showed no
significant difference between sites (p-value > 0.05) but significantly different between
stations (p-value < 0.05; R-statistic = 0.349))The result of the present study showed that the
marine nematode assemblages in Teluk Awar were mostly dominated by the functional
feeding group (FFG) of IB and 2B type except for station B2, A9 and B9. Vertical study of
nematode in Teluk Awar showed that at the depth of 0-5 cm, the recorded species were
Daptonema hirstum (70.48%) and Daptonema tenuispiculum (20.26%) with the average
similarity of 10.81. The nematode species was not found below 15 cm sediment depth.
Different pattern of nematode abundance is recorded in the sandy and muddy site for the
seasonal study. The seasonal study showed that the marine nematode community structure not
only affected by the particle size fractions (sandy /muddy) but also the seasonal rainfall. |
