This study aims to determine the type of seaweed that is good and can produce maximum growth and survival of Siganus guttatus. This research was carried out from June-September 2021, at at the Shrimp Hatchery Installation (IPUW), Barru, South Sulawesi. This study used a completely randomized design (CRD) used three treatments with three replications. The treatments used were treatment A (100% control of commercial feeding), treatment B (feeding Gracilaria sp. 100 %), treatment C (feeding Ulva sp.). The parameter measured were Specific Growth Rate (SGR), Absolute Growth, Survival and Palatability. The data was analyzed using Analysis of Variance (ANOVA) and with the W-Tukey test if there were differences between treatments. 180 Siganus guttatus juveniles (average weight of 5.65 g) were reared in a tanks (62x41x51 cm) for 75 days. The highest daily growth was obtained in commercial feed A (PF 1000) which was 1.53 g, the highest absolute growth was obtained in treatment A (Commercial Feed) 12.29 g, both treatments B (Gracilaria sp.) 4.30 g and the lowest was treatment C (Ulva sp.) .) 2.82 g. The highest survival rate (survival rate) was obtained in treatment A (Commercial Feed) and B (Gracilaria sp.) 98.33%, and the lowest was in treatment C (Ulva sp.) with an average value of 85.00%. Based on the results of the ANOVA test, it can be concluded that the research conducted by providing commercial feed (PF 1000), Gracilaria sp. and Ulva sp. significant effect (P<0.05) on specific growth, absolute growth, survival and palatability of baronang fish (Siganus guttatus). The results showed that the highest feed consumption value was in treatment A of 144.57 g, followed by Treatment B (Gracilaria sp.) of 142.19 g and the lowest of treatment C (Ulva sp.) of 100.01 g.
