Abstract
Present study is to examine effect of various microalgae on Fatty Acid (FA) of Portunus pelagicus larvae. Larvae were subjected
to five different treatments; T1, T2, T3, T4 and T5. T1: rotifer and Artemia only; T2: rotifer, Artemia and Chaetoceros sp.; T3:
rotifer, Artemia and Chlorella sp.; T4: rotifer, Artemia and Isochrysis sp. and T5: rotifer, Artemia and Nannochloropsis sp.
Highest FA component in Zoea 3 was saturated FA group of T2 with concentration 26.06±26.23mg/g. For monounsaturated FA
group, highest FA component in Zoea 1 was T5 with concentration 9.88±0.34mg/g. FA component in polyunsaturated FA group
in Zoea 4, T4 with concentration 9.33±0.45mg/g was highest. For survival rate, highest survival rate obtained from T4 with
10.21%±0.45. In this study, essential FA requirement in each stage of P. pelagicus larvae can be reveal. Species of microalgae
suitable for larvae can be characterized and selected for hatchery purpose.
