Abstract
ABSTRACT This current research aimed to find out survival and growth of snakehead fish ( Channa striata) reared in different pH media modification and to find out the optimum pH for rearing. Research was conducted in Aquaculture Laboratory, Aquaculture Program Study, Agriculture Faculty, Sriwijaya University from October toNovember2012. This researchcurrent used completely randomized design with five treatments and three replications. The treatments were P 0 (without treatments), P 1 (decreased from pH 5.75 to 3.00), P 2 (decreased from pH 5.75 to 4.00), P 3 (decreased from pH 5.75 to 5.00) and P 4 (increased from pH 5.75 to 6.00).  The result of this current research showed that the best survival rate and growth based on regression analysis growth and weight total biomass end was found for P 3 treatment (decreased from pH 5.75 to 5.00). Result of water physical and chemical measered were dissolved oxigen 4.32-4.77 mg.L -1 , temperature 26-28 0 C, and amonia 0.0030-0.1281 mg.L -1 . Keywords : Channa striata, Ikan gabus , pH Â
