The Effect of Aqueous Cattapa Leaf Extract on the Treatment of Gouramy Juvenile (Osphronemus goramy) Infected with Saprolegnia Sp.

Gouramy cultivation has obstacles in its development, one of which is disease. Disease attack fish farming activities a serious obstacle. The purpose this research was to determine the effect cattapa leaf solution (Terminalia goramy) on treatment juvenile gouramy (Osphronemus infected with fungal pathogen Saprolegnia sp. This study used completely randomized design method 5 treatments and 3 replications. given consisted A (control, without solution), while B, C, D E were 500 ppm, 1000 1500 ppm 2000 consecutively. parameters observed survival rate gouramy, scale growth intensity (scaled from 1 5) water quality. administration different doses did not significantly affect (p > 0.05). However, highest found B (500 ppm) 59% + 38.31 lowest (2000 at 21% 4.61. In-crease leaves concentration thought cause stress hence response feeding lower affecting rate. Infections still all although treated solution. In (1500 ppm), T. had slight reduction body where decrease several fish. Water quality such as temperature, pH, DO ammonia suitable con-dition for maintenance juvenile.
