Dietary administration of sea grape powder (Caulerpa lentillifera) effects on growth and survival rate of black tiger shrimp (Penaeus monodon)
Abstract
The objective of the study was to determine the dietary administration effect of sea grape powder (Caulerpa lentillifera) in the diet on the growth performance and survival rate of black tiger shrimp (Penaeus monodon). Two hundred forty shrimps (PL 15) averaging 0.0020 g were randomly distributed into 24 of 10 l tanks. The 10, 20, 30, 40 and 50 g/kg of sea grape powder was supplemented into six formulated feed. The result showed that the application of the sea grape (Caulerpa lentillifera) meal in the diet gave a significant effect on the weight gain, specific growth rate, daily growth rate, absolute length, feed conversion ratio, and feed utilization efficiency, but no significant effect on survival rate. The optimum weight gain, specific growth rate, daily growth rate, absolute length, feed conversion ratio and feed utilization efficiency were found at treatment D (30 g/kg diet) with the values were 0.20 gram, 7, 86% /day, 0.003 g/day, 26.6 mm, 0.81 and 123.84% respectively. Based on these result, it is concluded that the recommended level of sea grape powder dietary level (Caulerpa lentillifera) in shrimp feed (Penaeus monodon) was 30 g/kg.
