Stage		Seawater	Mixed water	Biofloc water
Postlarvae	Mean ± SD (cell/mL)	9.62 × 104a	9.53 × 105b	2.30 × 106b
	Range (cell/mL)	3.42 × 104 –4.78 × 105	6.19 × 105–1.57 × 105	5.59 × 106–1.28 × 107
Adult	Mean ± SD (cell/mL)	2.21 × 104a*	7.71 × 106b*	1.22 × 107b
	Range (cell/mL)	3.42–5.43 × 104	6.11–9.38 × 106	6.79 × 106–1.72 × 107

The significant difference between clear seawater, mixed and biofloc treatments for each stage is marked with different letters (p < 0.05).
A significant difference between the same treatments of the two different stages is marked with an asterisk.
