The purpose of this study was to determine the effectiveness of sweet potato leaf extract as an anti-stress in the process of transporting jelawat fish (L. hoevenii Blkr) fry. The experimental design used was a completely randomized design (CRD) with 4 doses of sweet potato leaf extract treatment, namely; Treatment A : Sweet Potato Leaf Extract With 2 mL/L Water Dosage, Treatment B: Sweet Potato Leaf Extract With 4 mL/L Water, Treatment C : Sweet Potato Leaf Extract With 6 mL/L Water, and Treatment D : Without Provision of Sweet Potato Leaf Extract (Control). Each treatment was replicated 3 times. The test parameters observed were blood glucose, glycogen levels, and survival rates (TKH). The results showed that the administration of sweet potato leaf extract with different doses gave significantly different effects on blood glucose levels of jelawat fish fry. The highest blood glucose levels were in treatment D (76.00 mg/dL), followed by treatment A (34.33 mg/dL), then treatment C (33.33 mg/dL), and treatment B (32.50 mg/dL). ). For glycogen levels at the beginning (0th hour) of 130 mg/100mL, and increased at 8th hour (end) to 175 mg/100mL for treatment A, 155.21 mg/100mL for Treatment B, 188.34 mg/ 100mL for Treatment C, and 197.41 mg/100mL for Treatment D. The best survival rate in this study was in treatment B (90.33%), then treatment A (85.67%), treatment C (83.00 %) and treatment D (80.00%).
