【 摘 要 】

Aeromonas hydrophylla was one of pathogenic bacteria in fresh and brackish water fish that reduced fish production. Betel leaf contains phenol active substances (carvacrol, betel phenol and chavicol), which act as anti-septic, kill microorganisms and prevent bacterial infection. This research aimed to know the effect of betel leaf flour feed supplement in different concentrations namely 2, 4 and 6 % applied to catfish and gourami. The design used in this research was completely randomized design, each treatment repeated three times. Results showed that the weight of catfish was not affected by the concentration of betel leaf concentration in feed. In contrast, gourami fed with higher concentration of betel leaf, gained more weight. The survival percentage of catfish 82.2, 96, 80% and gourami was 93.0, 88.8, and 93.3 % for treatment one, two and three respectively.
