Seasonal comparative of blood factors in farmed Beluga (Huso huso) in pen culture

This study designed to evaluate blood parameters of 3-4 years Huso huso on pen in the center of the fishing and processing Ashuradeh (Chalasht) from the Gorgan Bay in different seasons.Blood samples from 10 Huso huso withaverage weight2698.01 ± 757.32 g and length 77.98 ± 5.53 cm were collected in e...

Description
Summary:This study designed to evaluate blood parameters of 3-4 years Huso huso on pen in the center of the fishing and processing Ashuradeh (Chalasht) from the Gorgan Bay in different seasons.Blood samples from 10 Huso huso withaverage weight2698.01 ± 757.32 g and length 77.98 ± 5.53 cm were collected in each season (autumn 2014 to summer 2015) and activity of alanine transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and variation in hematological parameters such as hemoglobin, erythrocyte count, leucocytes count, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) in the blood samples of fish were measured in each season. There is significant difference in the enzymes levels were observed. (P<0.05). The lowest activity of aminotransferases and alanine aminotransferase were also observed in autumn. With the exception of mean corpuscular hemoglobin concentration (MCHC) that was the highest in the spring, the other blood parameters mentioned were highest in the autumn. The number of WBC (6.67 ± 0.35×103 mm3), RBC (0.97 ± 0.01×106 mm3) and hemoglobin values (6.96 ± 0.15 g/dl) had its lowest level in winter. But the levels of hematocrit (.80 ± 0.62), hemoglobin, MCV and MCH values respectively 187.50 ± 3.87 fL and 63.36 ± 1.45 pg/cell showed the lowest level in spring. The results of this study showed seasonal variations effect on haematological parameters in Huso huso and should be considered when these parameters are utilized to evaluate fish health status.
