Growth Performance of Mahseer Fingerlings (Tor soro) Fed Potassium Diformate Added Diets

Mahseer aquaculture activities are still relatively low because they constrained by slow growth. Potassium diformate can promote growth improving digestion. This research aimed to determine the optimum dose of potassium addition artificial feed for best rate in mahseer fingerlings. The was conducted from July – August 2022, hatchery Faculty Fisheries and Marine Sciences, Padjadjaran University, West Java, Indonesia. method used this experimental, using a completely randomized design (CRD) consisting four treatments five replications. test fish were 200 fingerlings measuring 4.5 5.0 cm. treatment formate at 0% (A), 0.1% (B), 0.3% (C), 0.5% (D). length maintenance is 40 days, with amount feeding 3% fish's body weight. Parameters observed included specific (SGR), conversion ratio (FCR), survival (SR), water quality (dissolved oxygen, temperature, pH). results showed that gave highest SGR value 0.75%, FCR 3.80, EP 26.87%, SR 100%. It be concluded difomate has good effect on if given optimal doses.
