TABLE 3.

Growth and survival rate of Penaeus monodon in test tanks and controls^a

Group	Survival rate (%)	Length (mm)		Length gain (%)	Wt (g)		Weight gain (%)	ADG (mg · day⁻¹)
Group	Survival rate (%)	Initial	Final	Length gain (%)	Initial	Final	Weight gain (%)	ADG (mg · day⁻¹)
Control	31.0 ± 1.2^A	12 ± 0.1^A	86.0 ± 11.1^A	616 ± 92^A	0.1 ± 0.02^A	4.21 ± 1.56^A	4,124 ± 155^A	48.4 ± 18.4^A
Test	48.1 ± 2.1^B	12 ± 0.1^A	99.8 ± 10.0^B	732 ± 83^B	0.1 ± 0.02^A	6.36 ± 1.50^B	6,299 ± 147^B	73.6 ± 17.6^B

Data are expressed as means ± standard deviations. Means with different superscript letters were significantly different (P < 0.05). ADG, average daily weight gain. The data were collected from the surviving shrimp in each of the six tanks at the end of the experiment, which was an average of 351 in the test tanks and an average of 180 in the control tanks. One hundred thirty shrimp in each tank were sampled during the test. The number of surviving shrimp was the number of shrimp counted at the end of the test plus the number of shrimp sampled during the test. The survival rate was calculated from the number of surviving shrimp divided by the total number of shrimp at the start of the experiment. One thousand shrimp were added to each of the six tanks at the start of the experiment.
