Abstract:
The physiological condition in fishes required for
their selection as broodfish can be determined by hematological studies. The
present study aims at examining the hematological indices in juvenile
sturgeons at different stages of growth. The main blood features, such as
total albumin content in blood, hemoglobin concentration and the erythrocyte
and leukocyte count, were measured in a total of 54 specimens of 1-, 2- and
6-year old sturgeon (Persian sturgeon Acipenser persicus and beluga Huso
huso), artificially produced at the Shahid Dr. Beheshti Fish Breeding and
Rearing Center located in the Gilan Province.In the Persian sturgeon
specimens studied, the total albumin concentration in the blood increased
from 26.05 to 52.50 g l(-1), the hemoglobin concentration increased from
42.2 to 65.8 g l(-1), the erythrocyte count increased from 240 to 452.5
thousand cell ml(-1) and the leukocyte count increased from 13.43 to 46.48
thousand cells ml(-1). The total leukocyte was composed of 73.25 to 82.70%
lymphocytes, 12.3 to 20% neutrophils, 2.25 to 6.50% eosinophils and 0.2 to
2.5% monocytes. In the beluga specimens studied, the total albumin
concentration in the blood increased from 20.05 to 42.20 g l(-1), the
hemoglobin concentration increased from 46.3 to 78.6 g l(-1), the
erythrocyte count increased from 495 to 735 thousand cells ml(-1) and the
leukocyte count increased from 31.6 to 57.7 thousand cells ml(-1). The total
leukocyte was composed of 54.5 to 67.5% lymphocytes, 22.63 to 33.86%
neutrophils, 6.60 to 13.7% eosinophils and 0.6 to 2.25% monocytes.This
research reveals the trends of some hematological features during the growth
and development of sturgeons in the South Caspian Sea, reared in artificial
conditions. It shows that with the increase in age, the hematological
indices also increased.
