            Ikan nila merah mampu beradaptasi pada kondisi salinitas yang luas serta tahan terhadap kondisi perairan yang ekstrim dan mempunyai sifat euryhalin sehingga penulis tertarik untuk melakukan penelitian ini, dengan tujuan untuk mengetahui kondisi isoosmotik dalam pemanfaatan energi untuk  kelangsungan hidup, pertumbuhan dan efisiensi pakan bagi benih ikan nila merah (Orechromis niloticus). Penelitian ini berlangsung pada bulan Februari s/d Maret 2012, menggunakan metode rancangan acak lengkap (RAL) terdiri atas 4 taraf perlakuan yaitu 0, 10, 20, 30 ppt dan 3 kali ulangan, sehingga jumlah satuan percobaan adalah 12 unit. Ikan uji yang digunakan yaitu benih ikan Nila merah memiliki bobot awal kurang lebih 0,646 gr  dan panjang awal kurang lebih 2 cm yang dipelihara pada akuarium bersekat dengan ukuran 20 x 40 x 40 cm3. Data yang diperoleh dianalisa menggunakan analisis ragam uji F dan uji jarak berganda Duncan pada taraf kepercayaan 95%, penyajian data menggunakan diagram batang. Dari hasil penelitian ini menunjukan nilai presentasi kelangsungan hidup pada perlakuan A (84,16 %),  B (85,33 %) dan C (85,83 %) masing – masing tidak berbeda nyata dengan perlakuan D (16,25 %). Pertumbuhan optimal rata – rata berada pada perlakuan A (4,02 gr) dan efisiensi pakan optimal berada pada perlakuan C (176,0 %). Untuk kualitas air yaitu suhu berada pada kisaran 26,40 C s/d 280 C dan  DO  berada pada kisaran  5,2  s/d  6,0 mg /L.

          Red tilapia are able to adapt to a wide salinity conditions and resistant to extreme water conditions and have a nature euryhalin so interested in doing this research, in order to determine the isosmotic conditions in the utilization of energy for survival rate, growth and feed efficiency of red tilapia juvenil (Orechromis niloticus). This study took place in February until March 2012, using the completely randomized design (CRD) consisting of four (0, 10, 20, 30 ppt) and three replications, with is experimental units is 12 units. Test fish used is red Tilapia juvenil initial weight ± 0.646 g and length ± 2 cm. Fish maintained in aquarium 20 x 40 x 40 cm3. For the data obtained were analyzed using analysis of various test F and Duncan multiple range test at 95% level of confidence. This result showed that there were to significant differences betwean A (84.16%), B (85.33%) and C (85.83%) in survival rate but significant with D (16.25%). Optimal growth was from treatment A (4.02 g) and feed efficiency were optimal from treatment C (176.0%). Water quality observed was temperature about 26.40 C – 280 C and DO about 5.2 – 6.0 mg / L.
