Abstract: The experiment comprised five treatments including a control without any organic carbon addition and four different carbon sources applied in biofloc system namely sugar cane molasses, fine rice bran, cassava powder and combination of rice bran and cassava at an estimated C:N ratio of 12. The nursery phases were assessed in tanks with a volume of 450 L for 30 days. The black tiger shrimp (Penaeus monodon) postlarvae with an average weight of 0.01 g were randomly stocked at density of 600 Ind. m-3. Results showed that carbohydrate addition resulted in better water quality and shrimp performance than that in the control system. Among the different carbon sources used, cassava and molasses have slightly increased the survival of shrimp. Overall, use of sugar cane molasses as carbon source seem to be more effective that gave better water quality, survival and production of shrimp.
