Abstract

This research was performed to examine the effect of soaking ginger liquid in artificial feed on growth, survival, feed efficiency and profit in giant gourami (Osphronemus goramy) cultivation. A 40-day experiment was conducted using giant gourami seeds with an average size of 4.14 g (±0.85 g) reared in 0.4 m3 aquariums with 16 fish each. Water recirculation was applied in water quality control. The feed used in this research was soaked in ginger liquid with different doses; 0.1% (treatment A), 0.25% (treatment B), and 5.0% (treatment C) with 3 replications. The results of this research showed that the right dose of ginger enrichment in artificial fish feed improved several parameters of the giant gourami fish cultivation, including weight growth rate (WGR), survival rate (SR), feed conversion ratio (FCR), and benefit/cost ratio (BCR). Treatment B resulted in the best performance. The modeling results show that the optimal dose of ginger treatment is 0.3%.
