| Abstract | ||||
| The Siamese catfish (Pangasius hypophthalmus) holds significant economic value, with increasing demand for its production. The quality of feed—particularly its nutrient content—plays a crucial role in catfish growth. Fish meal, a conventional protein source, often encounters supply challenges, making mealworm (Tenebrio molitor) flour a promising alternative, offering up to 45.88% protein content and 35% fat content. This study aimed to evaluate the effect of replacing fish meal with mealworm flour on the growth and survival of Siamese catfish. The experiment was conducted using a completely randomized design (CRD) with five treatments: A (0% mealworm flour, 100% fish meal), B (25% mealworm flour, 75% fish meal), C (50% mealworm flour, 50% fish meal), D (75% mealworm flour, 25% fish meal), and E (100% mealworm flour, 0% fish meal), each with three replications. The fish used in the study had an average length of 8.44 ± 0.575 cm and an average weight of 3.86 ± 0.72 grams, with a stocking density of one fish per 5 liters in 50×50×100 cm nets. The maintenance period lasted 49 days, with feeding provided twice daily to satiation. The findings indicated that substituting fish meal with mealworm flour had a significant effect (P< 0.05) on growth parameters. Treatment B (25% mealworm flour) produced the most favorable outcomes, with total feed consumption (TFC) of 215.70 ± 0.74g, feed efficiency (FE) of 79.51 ± 0.88%, feed conversion ratio (FCR) of 1.19 ± 0.05, specific growth rate (SGR) of 2.95 ± 0.02%/day, and absolute weight gain of 171.51 ± 1.66g. | ||||
