Diets	Crude protein	Crude lipid	Crude ash	Moisture
Con	3.96 ± 0.02	0.94 ± 0.03c	0.63 ± 0.03	89.5 ± 0.46
PHB25	3.96 ± 0.02	2.34 ± 0.01b	0.63 ± 0.02	89.0 ± 0.45
PHB50	4.07 ± 0.11	3.98 ± 0.03a	0.63 ± 0.01	90.2 ± 1.09

The Artemia nauplii was enriched with different levels of poly-β-hydroxybutyrate by 0, 0.25 and 0.5% (designated as Con, PHB25 and PHB50, respectively).
Values (mean ± SD) are average of triplicates (n = 3). Values with different superscripts in the same column are significantly different (p < 0.05).
