Optimal salinity on rearing media is needed to get the best production performance of climbing fish culture. The aim of this experiment is to get an optimal salinity on rearing media of climbing fish. This experiment was conducted in wet lab of Research Institute for freshwater Aquaculture and Fisheries Extension. The treatments were different salinities on rearing media; 0 ppt, 3 ppt, 6 ppt and 9 ppt. Each treatment has 3 replicates. Experiment design use completely randomized design. The initial weight of fish was 1 ± 0.11g and initial length of fish was 2 ± 0.3 cm. Aquaria of 40x22x20 cm was used for rearing media. Each aquarium with 15 lt of water was stocked 350 fish. Fish was fed frozen blood worm (protein contains of 62.5%) at ad libitum. Duration time of rearing was 40 days. Sampling was conducted every 10 day for fish weight, lenght and water quality. The result showed that optimal salinity of survivale rate, specific growth rate and total length were on salinity of 1.8 ppt, 2.5 ppt and 3.3 ppt. The value of water quality parameter in aquaria such as temperature, pH, Oxygen, nitrite, nitrate an amonia is still feasible for climbing fish rearing.
