Abstract
The aim of this study was to identify suitable carbon sources for the growth and survival of larvae of white-leg shrimp nursed in tanks with biofloc technology. The experiment was conducted with five treatments: (i) no carbon supplement (control), (ii) carbon supplement from wheat flour, (iii) carbon supplement from rice bran, (iv) carbon supplement from wheat and rice bran at a ratio of 50:50 and (v) carbon supplement from sugar. Each treatment was triplicated. The experimental tank was 500 liters in volume. Stocking density was 150 larvae/liter and water salinity was 30‰. Results of the experiment showed that the body length of 12-day old postlarvae (PL12) in the sugar treatment (10.18±0.15mm) was the highest and significantly different (p0.05) compared to the other treatments. The survival rate (52±5.1%) and productivity (78±8 larvae/liter) of PL12 in the sugar treatment were also the highest and significantly different (p
