This study aims to determine the effect of different salinities on the growth and survival of baung fish (Hemibagrus nemurus) fry. The method used is an experimental method with a complete random design (RAL) consisting of 5 treatments with 3 repeats, namely P1 = salinity of 3 ppt, P2 = 4 ppt, P3 = 5 ppt, P4 = 6 ppt, and P5 = 7 ppt. The results showed the best treatment in P4 treatment of baung fry rearing with a salinity of 6 ppt, resulting in absolute weight growth of 0.73±0.04 gr, absolute length of 1.88±0.19 cm, daily growth rate of 3.50±0.19%, feed conversion of 1.69±0.08, and survival of 98±3.46%. The range of water quality during maintenance was supportive for baung fry, with temperatures ranging from 25–28 0C, pH 6.2–6.78, dissolved oxygen content 6.0–7.7 mg/L, and ammonia ranged from 0.59–1.88 mg/L.
