【 摘 要 】

The purposes of this research were to determine the effect of alkaloid jellyfish compounds on intestinal histopathology of tiger grouper and to determine the best doses to the relative percent survival (RPS) of tiger grouper. The method of this research was descriptive with completely randomized design. The treatment of active alkaloid compound on feed was investigated for 28 days. The fish were then challenged with Vibrio harveyi at 105CFU/cell for 7 days. Alkaloids were added to the feed with the doses (g alkaloid/kg feed) of 0 (control); A = 0.5; B = 0.75; C = 1.0; and D = 1.25. The intestinal histopathology and RPS were observed. The best RPS was found at a treatment of C with the value of 100 %.
