Study on some hematological factors of Salmo trutta caspius

Regarding to measure some hematological factors of Caspian Salmon (Salmo Trutta caspius), 55 immature and 21 mature individuals were studied. The main results were: 
Immature
Mature
- Hemoglobin value (gr/dl)
7. 20
9. 87
- Hematocrit
34. 1
39. 2
- Mean No. of red blood cells (per mm3)
934300
1306200
- Mean No. of white blood (per mm3)
8380
6219
- Mean No. of platelets (per mm3)
21180
13159
As the results showed the number of white blood cells and platelets in immature individuals were more than mature specimen.
The obtained results of blood indices were as follow: 
Immature
Mature
- Mean MCV (FL)

302. 9
-  Mean MCH (Pg)
82. 0
75. 5
- Mean MCHC (%)

25. 6
- Lymphocyte (%)
96. 1
69. 9
- Neutrophil (%)
3. 4
29. 4
- Monocyte (%)
0. 52
