<![CDATA[This study aimed to analyze the effect of adding Viterna Plus to artificial feed at different doses on the growth, survival, and length–weight relationship of Siamese catfish (Pangasius hypophthalmus), as well as to determine the optimal dose for the best performance. The research was conducted at Si Pujuk Farm, Padang City, over 40 days using a Completely Randomized Design (CRD) with four treatments: P0 (without Viterna Plus), P1 (7 mL/kg feed), P2 (14 mL/kg feed), and P3 (21 mL/kg feed), each with three replicates. Observed parameters included specific growth rate (SGR), absolute weight and length growth, feed conversion ratio (FCR), survival rate (SR), length–weight relationship, and water quality. The results showed that the 14 mL/kg feed treatment (P2) produced the highest mean values for SGR (1.05 ± 0.25%), absolute weight (20.23 ± 11.86 g), absolute length (2.05 ± 0.38 cm), the lowest FCR (10.85), and the highest SR (97.77 ± 3.84%). Analysis of the length–weight relationship indicated a b value < 3, suggesting negative allometric growth, meaning that length increased faster than weight. Based on ANOVA results, the addition of Viterna Plus had no significant effect (P > 0.05). Throughout the study, water quality remained within the optimal range for Siamese catfish cultivation]]>
