Abstract: Barramundi is one of the cultivated commodities which is being developed at this time. One of the challenges in Barramundi Aquaculture is the low survival rate due to internal mortality during the larval phase. Adequate feed supplementation, both in quantity and dose can be a solution in preventing mortality in fish larvae. The research objective was to analyze the effect of SCP on survival and mortality in barramundi larvae. This study used a plastic tub with a round shape and filled with 25 liters of water. The study was designed using a completely randomized design (CRD) method with 4 treatments and 3 replications. The treatment doses used is 0, 100, 200, and 300 mg / L.
