Description
ABSTRACT The culture of Litopenaeus vannamei in low-salinity waters is now popular in many regions of the world, A 6 x 3 factorial experiment was conducted to determine the effects of salinities (tap water, 1 [per thousand], 2 [per thousand], 4 [per thousand], 8 [per thousand], and 16 [per thousand]) and dietary carbohydrate levels (15.47%, 29.15%, and 41.00%) on survival, growth, food consumption, food efficiency, absorption efficiency, and energy budget of juvenile L. vannamei. The results showed that no shrimp survived in tap water at the end of the experiment irrespective of dietary carbohydrate (CBH). At each dietary CBH level, the specific growth rate (SGR), food consumption, and food efficiency generally increased with increasing salinity within the range of 1-16 [per thousand]. At salinities of 1 [per thousand], 2 [per thousand], 4 [per thousand], 8 [per thousand], and 16 [per thousand], optimal CBH levels corresponding to maximum SGR decreased with increasing salinity and were 29.87%, 27.59%, 26.85%, 26.25%, and 22.29%, respectively. At 1-8 [per thousand], the percentage of consumed energy deposited in growth (%C) was significantly higher in shrimps fed 29.15% CBH as compared with other treatments, whereas at 16 [per thousand], the significantly higher value was in those fed 15.47% CBH.
