Abstract: The main problem faced by swimming crab hatchery today is the low survival rate of larval stages, especially zoea to megalopa. This research aims to examine the effect of dissolved glucose administration on survival and performance of swimming crab larvae of Portunus pelagicus in the zoea stadia to megalopa. This research was conducted at the Brackish Water Aquaculture Fisheries Center of Takalar, Takalar Regency, Province of South Sulawesi. Swimming crab larvae of zoea-1 are maintained in a black plastic basin with a volume of 40 L totaling 24 pieces equipped with aeration equipment and filled with water by salinity 32 ppt as much as 30 L. Feed given is rotifers and Artemia salina with the addition of dissolved glucose. The research was designed using a Completely Randomized Design (CRD) with 4 dose treatments of dissolved glucose with 3 replications. The four doses are 0, 50, 100 and 150 ppm. The results of Analysis of Variance (ANOVA) showed that the administration of dissolved glucose had a very significant effect (p<0.01) on glycogen content, stress resistance, and swimming crab larvae survival. The glycogen content, stress resistance and survival rate were produced at a dose of 100 ppm, respectively 4.31%, 91 and 39.22%, while the lowest at a dose of 0 ppm respectively 3.14%, 119 and 9.15%.
