Analysis of the fatty acid composition as percentage of total fatty acids of wild juveniles of sea bass caught off the western coast of the Malaysian Peninsular showed that more than 38% of total fatty acids consisted of the two essential ones, 20:5w3 (eicosapentaenoic acid) and 22:6w3 (docosahexaenoic acid). Laboratory-reared larvae had lower contents of 20:5w3 and 22:6w3. In both wild and cultured juveniles, the 16:0 and 18:1 were high while the latter had higher 18:3w3 (linolenic acid) and 18:2w6 (linoleic acid). Juveniles suffering from whirling disease had very low concentrations of 20:5w3 (2.9%) and 22:6w3 (0.02%). Their proportion of 18:3w3 at 9.4% and 18:2w6 at 18.4% were high. .

Analiza składu procentowego kwasów tłuszczowych u narybku Lates calcarifer odłowionego u zachodniego wybrzeża Półwyspu Malajskiego wykazała, że ponad 38% kwasów tłuszczowych stanowiły 20:5w3 (kwas eikozapentaenowy) i 22:6w3 (kwas dokozaheksaenowy). Larwy hodowane w laboratorium miały niższą zawartość tych kwasów. Zarówno u narybku dzikiego jak i hodowanego poziom 16:0 (kwas palmitynowy) i 18:1 (kwas oleinowy) był wysoki, lecz narybek hodowany miał więcej 18:3w3 (kwas linolenowy) i 18:2w6 (kwas linolowy). Osobniki cierpiące na kołowaciznę miały bardzo niską zawartość 20:5w3 (2,9%) i 22:6w3 (0,02%). Duży był u nich udział 18:3w3 (9,4%) i 18:2w6 (18,4%).
