The aim of this research was to observe the impact of different saline media towards the survival rate and growth of red tilapia, variety Larasati Tilapia (O. niloticus) F5 seed cultured in saline media. This research was carried out on March - August 2012 at Satker PBIAT (Centre of Fresh Water Fish Hatchery Working Unit), Janti – Klaten, Central Java Province. Sample used were F5 red Larasati Tilapia seed from selective breeding with approximate length of 3-5 cm. A completely randomized design method was used with 5 treatments and 3 replications. Different saline media for the treatments were A (0‰); B (15‰), C (20‰), D (25‰) and E (30‰). The seeds were cultivated in a plastic container with water capacity of 20 liter and density of 20 fish per container. Result showed that in water media with salinity up to 15‰ the survival rate is equal to salinity of 0‰ at amount of 81.67±2,89%. Increase in salinity of the media result in the decrease of the survival rate where at the saline media of 30‰ the survival rate drops until 71.67±2,89%. Similarly, growth in weight and length. F5 red Larasati tilapia reared in saline media up to 30‰ are still experiencing good growth both in weight and length, but slowed. The best growth was obtained in 15‰ saline medium with gaining in weight and length for 1.40±0.01 grams and 1.89±0.02 cm, respectively
