The high demand for shrimp exports encourages increased demand for shrimp seeds as one of the inputs in vannamei shrimp cultivation. However, the problems that are often faced in hatcheries are slow growth, non-uniform size, long time transfer stage and vulnerable to environmental changes. so that growth acceleration is needed in changing the metamorphosis rate of vaname shrimp, namely by multi amino acids. This study aims to determine the concentration of multi dissolved amino acids on the best acceleration of metamorphosis and growth of vaname shrimp seeds. The research was carried out at the Brackishwater Aquacultur Development Center, Takalar.The test animals used were vaname shrimp seeds from Zoea-1 to PL-10 stages which were stocked at a density of 40 individuals / 25 L. The study was designed using a completely randomized design (CRD) consisting of 4 treatments with 3 replications each, namely the amino acid doses of 0, 5, 10, and 15 ppm. The parameters measured were larval survival and metamorphosis of vaname shrimp. From the research results, The best survival rate was obtained at 100 ppm treatment 69.63 ± 0.82% with metamorphic rate of zoea, mysis and post larvae respectively 92.5%, 80.5% and 69.63% resulting in a uniformity level of 85.11%.
