ABSTRACT=Different types and inclusion levels of palm oil were incorporated in the enrichment diets of L-type rotifer, Brachionus plicatilis, and fed to Asian seabass (Lates calcarifer) larvae. The dietary fish oil was replaced with either 50% or 75% of crude palm oil, CPO (CPO50, CPO75) and refined bleached deodorized palm olein, RBDPO (RBDPO50, RBDPO75). The enrichment diet with 100% fish oil (FO100) and a commercial enrichment product (SELCO) were used as experimental controls. Rotifer was enriched for 18 hours prior to first feeding of Asian seabass larvae. Triplicate groups of fish larvae with initial length of 2.72±0.14 mm were fed with enriched rotifer for 15 days. Palm oil-based enrichment diets performed better than the control diet (FO100). The performance of RBDPO75 was similar to SELCO. The dietary enriched rotifer with palm oil significantly affected the body proximate and fatty acid profiles.  The present study suggests that RBDPO and CPO can be considered as a good alternative dietary lipid in the enrichment diets for the rotifer during larval rearing of Asian seabass.
