AB  - The effects of changes in salinity levels on some haematological indices of <I>S. melanotheron</I> were studied.  The fish were sampled from the wild of salinity 12% and transferred to laboratory where the salinity which was level gradually reduced by 2 units everyday to 0.34% over a period of seven days. This caused a consistent reduction (p< 0.05) in the blood characteristics with the value of haemoglobin 6.38±0.71 to 4.81 0.98 (g dL <SUP>1</SUP>); packed cell volume 19.03±1.38 to 16.50±2.59%, leucocrit 5.60±1.27 to 4.74±1.36%, red blood cell 2.50±0.14 to 1.50±0.44 (×10<SUP>12</SUP>cells), mean corpuscular haemoglobin concentration 33.83±5.31 to 31.56±9.13 g dL <SUP>1</SUP> thrombocytes 177.22±19.54 to 158.67±21.87 (×10<SUP>9</SUP>cells) and lymphocytes 44.63±6.67 to 34.60±7.40%.  However, the other parameters in the treated group had an increment (p< 0.05) in the values white blood cells 30.00±4.30 to 31.40±4.17 (×10<SUP>9</SUP>cells); neutrophils 34.52±4.57 to 39.40±4.42%, mean corpuscular volume 76.26±6.06 to 118.82±38.45 (pg); mean corpuscular volume 76.27±6.08 to 118.82±38.45 (fl) and monocytes 2.53±0.63 to 3.01±0.72%. This study shows that gradual reduction in salinity levels exerts some degree of stress in the blood characteristics of <I>S. melanotheron</I> and that such changes could either be a reduction or an increase in the values depending on the parameters.
