Abstract:
Study of fatty acid biomarker was done in order to investigate the organic food
source of Mudskipper species, Boleopthalmus boddarti and Periopthalmus gracillis in
Setiu Wetlands. Both species are dominant species of mudskipper in Setiu Wetlands.
Analysis was done to find and compare both species organic food source and
sediment with fatty acids markers
Data obtain shows that B. boddarti (0.077 g g-
1
dry wt.) has the highest total
lipid content, followed by P. gracillis (0.057 g g-
1
dry wt.). Sediment has the least
total lipid content (0.009 g g-
1
dry wt.). In P. gracillis tissues, 15 F As component
found and in B. boddarti tissues there 18 component of F As. In fatty acid
composition, SAFA (saturated fatty acid) are the mainly fatty acid found in tissues

3.503 g g-
dry wt. in P. gracillis, 2.168 g g-

dry wt. in B. boddarti and sediment
samples 1.866 g g-1 dry wt. MUFA (monounsaturated fatty acid) also occur in high
1
level content with 1.140 g g-
dry wt. in P. gracillis , 0.950 g i

boddarti and 0.278 g g-

the least fatty acid classes found with only 0.012 g g-
