A study on the distribution and abundance of the macrobenthos was conducted at
estuaries of Setiu Wetland and Kuala Ibai. Each location has 3 substations plotted with
3 replicates collected. The macrobenthos samples were collected using 0.1m Ponar
grab and were sieved using 0.5 mm mesh sieve. The remaining sample were preserved
in 10% formalin before the organisms were identified to the lowest possible taxonomic
level. The sample collected at Setiu Wetland recorded with 112 organisms while Kuala
Ibai only 43 organisms which come from 8 Families. Setiu Wetland-S1 recorded the
highest abundance of macrobenthos with 55 organisms while the Kuala Ibai-S1
recorded the lowest with only 8 organisms. The dominant family obtained is
Potamididae. For organic matter, the highest percentages were recorded in Setiu
Wetland station 1 which is 2.17% while for Kuala Ibai station 2 is 1.67%. In general,
Setiu Wetland is more abundant than Kuala Ibai.
