<![CDATA[One of the main challenges in the production of vannamei shrimp larvae is the low quality of the resulting post larvae. This is generally caused by the feed quality and nutritional content that do not adequately meet the optimal requirements of the post larvae. This study aims to evaluate the growth performance and survival of vannamei shrimp post larvae at PL 4-10 stages with feed treatments using Artemia sp. and artificial powder feed, as well as to determine the best type of feed. The study was conducted in May at CV. Sumber Hatchery Bangka using an experimental method with a Completely Randomized Design (CRD), consisting of three treatments and five replications: treatment A (100% natural feed with Artemia sp. nauplii), treatment B (100% artificial powder feed), and treatment C (a combination of 50% natural Artemia sp. nauplii and 50% artificial powder feed). Post larvae were stocked at a density of 20 individuals per liter, totaling 10,000 larvae per tank. Parameters observed included absolute weight gain, absolute length increment, survival rate, and water quality. Data were analyzed using ANOVA with a 95% confidence level followed by a Least Significant Difference (LSD) test. The results showed that treatment C produced the highest absolute weight gain (0.009±0.001 g), which was significantly different (p<0.05) from treatments A (0.008±0.001 g) and B (0.007±0.001 g). Treatment C also resulted in the highest absolute length increment (0.456±0.044 cm), significantly different from treatments A (0.394±0.032 cm) and B (0.386±0.047 cm). The highest survival rate was found in treatment A (96±0.038%), followed by treatment B (95±0.025%) and treatment C (91±0.037%). Water quality during the study remained within the optimal range according to SNI 8678-4:2021 standards for vannamei post larva maintenance. In conclusion, the combined feed treatment yielded the best growth performance, whereas 100% natural feed resulted in the highest survival rate.]]>
