N2 - This study evaluated the effect of different salinity levels on the physiology of East Java strain tilapia (Oreochromis niloticus) by measuring the serum osmolalities (SO), ion levels and hematological parameters. Their SOs above the external medium (hyper-osmotic) at 0 and 5 ppt, becoming iso-osmotic at 10 ppt and hypo-osmotic at 15 ppt. The concentrations of serum Na+, K+, Cl− and Ca2+ in fish acclimated in 0 and 5 ppt were not significantly different. The levels of Na+, Cl– and Ca2+ in fish exposed to 10 and 15 ppt were higher than those in fish acclimated at 0 and 5 ppt. In contrast, the levels of K+ in fish exposed to 10 and 15 ppt were lower than those in fish exposed to 0 and 5 ppt. The levels of red blood cell, hematocrit and hemoglobin of fish exposed to salinity of 0, 5, 10 and 15 ppt were not significantly different. The levels of white blood cell increased significantly at fish exposed to 10 and 15 ppt. These data provide useful information for future reference and farming practice.
