This study was carried out to determine the distribution, abundance and the dominant
species of Annelida in estuaries of Setiu Wetland and Kampung Mangkuk. Family
Capitellidae is dominant species at Station 1 in Setiu Wetland while family Nephtyidae
at Station 2 in Kampung Mangkuk. The sediment samples were collected using 0.1
m² Ponar grab and were sieved using 0.5 mm mesh sieve. Then, the collected
organisms were fixed in 10 % formalin before been brought to the laboratory for
further identification to the lowest possible taxonomic level. A total of 87 individual of
annelids were counted at all stations and the highest abundance of annelids belong to
Capitellidae family which has 40 individual. The highest percentages of organic content
were recorded in Station 2 for both area which is 2.17 % for Setiu Wetland and 2.67
% for Kampung Mangkuk. Overall, depth, type of sediment texture and organic
content become the factors that influence the distribution and abundance of annelida.
