| Abstract: | A 3×3 factorial experiment was conducted to determine the effects of water temperature (22 °C, 27°C and 32°C) and dietary
carbohydrate (CBH) levels (15.47%, 29.15% and 41.00%) on growth, food consumption, feed efficiency, apparent digestibility coefficient and
energy budget of juvenileLitopenaeus vannamei. The results showed that, at each dietaryCBH level, specific growth rate, food consumption and apparent digestibility coefficient generally increased, while feed efficiency
decreased with increasing water temperatures. Specific growth rate and food consumption were the highest in the shrimps fed
with diet of 29.15%CBH, closely followed by those with 15.47%CBH, and those with 41.00%CBH had the lowest value.
