Crayfish culture (Cherax sp) is currently a business opportunity in aquaculture. Cherax sp is one of the local and export commodities. The increasing demand every year, crayfish culture with high productivity is needed. The increase in culture is largely determined by the growth and survival of the crayfish. One alternative that can be applied is the use of probiotics and prebiotics. Lactobacillus sp has been widely used in aquaculture as a probiotic. While coconut pulp contains galactomannan which can function as a prebiotic and is one of the agricultural wastes that can be used as animal feed. The aim of this study is to determine the growth and survival rate of crayfish given probiotics and prebiotics. The experimental design used was a completely randomized design. This study consisted of three treatments with three replications. Treatment A (maintenance of freshwater crayfish without the addition of Lactobacillus and coconut powder), Treatment B (maintenance of freshwater crayfish with the addition of Lactobacillus 2%/kg of feed), and Treatment C (maintenance of freshwater crayfish with the addition of Lactobacillus 2%/kg of feed and coconut powder 2 %/kg feed). Parameters observed were daily growth rate (DGR), survival rate (SR) and water quality. The result from this study showed that DGR has significantly different between A treatment and B, C treatment. But SR showed has not significantly diferrent between the treatments. The highest SR shown in C treatment.
