| Sumario: | Giant Gouramis (Osphronemus gouramy) is one type of freshwater fish that has a lot of interest and market demand is quite high. The cultivation of giant guramis is still constrained because of its relatively slow growth. Kelakai (Stenochlaena palustris) is one alternative that can be used as additional feed for giant gouramis because it has a high protein content of 27.31%. The problem with the use of kelakai for fish feed is the high crude fiber content. This nutritional value can be improved through the silage process or fermentation for feed or feed ingredients using microbes (addition of probiotics). Silage comes from forage or agricultural waste that is preserved in a fresh state through a fermentation process in a container.The study aimed to evaluate the growth and survival rate of giant gouramis. This study used a Complete Random Design with 4 Treatments with 3 repetitionsconsisting of Treatment 1 (K0): Pellet + fresh kelakai leaves: Treatment 2 (K1): Pellet + Kelakai leaves Silage for1 day incubation; Treatment 3 (K2): Pellet + Kelakai leaves Silage for 2 days incubation; Treatment 4 (K3): Pellet + Kelakai leaves Silage for3 days incubation. The results showed that the relative weight growth rate ranged from 21.13-25.16%, the relative length growth of the body ranged from 1.5-1.57%, survival ranged from 72-82% and the feed conversion rate ranged from 1.5-1.69. |
