Abstract

In this investigation, two hematological factors of hematocrit and hemoglobin and their changes regarding to different salinities were studied in common carp.
 Seven aquarium (with 100 lit. volume for each) were chosen and the water salinity of each one were adjusted to 0, 3, 6, 9, 12, I5 and I8 ppt, respectively.
 16 specimen of common carp with 50-90 g body weight were added to aquariums. The blood samples of fishes were collected in periods of 12 to 96 hour for further hematological measurements. The results showed that in salinity of 18 ppt. all fishes died after less than 12 hours. In Stress condition, the minimum and maximum hematocrit index were found 13 to 45% and hemoglobin factor were varied from 5.0 to 12.2 g/lit.
