Sağım Dönemi̇nde Alabalıklarin Trout (Oncorhynchus mykiss) Kan Parametreleri̇ni̇n Araştırılmsı

In this study, trout (Oncorhynchus mykiss) from the facilities located in Doganşehir Sürgü, Malatya was used. Samples were received betweenNovember 2017 and January 2018. During the study, a total of 60 fish, 10 female, 10 male, 10 female, 10 male and 10 female, were studiedin the pre-milking period. After the fish were anesthetized with 0.25% phenoxyethanol, blood was taken from the tail end with the help of theinjector. Blood samples were taken from the alveolar vessels and measured with the PROKAN 6800 VET device. Hematological analyzes wereperformed using the Cell DN 1700 coulter counter to determine blood parameters. The weight of male fishes before mating was 359.5 ± 32.7g, increased to 453 ± 74.09 g during the mating period and decreased to 354 ± 99.35 g at the end of mating period. In females, before matingperiod weights were 421 ± 28.46 g, decreased to 375 ± 54.62 g during the mating period and increased to 392 ± 75.69 g after the mating period.The blood parameters obtained for male fish are as follows; white blood cells (WBC): 50.8 ± 14.82 103/μL before mating, 55.79 ± 2.79 103/μL during mating, 54.61 ± 3.052 103/μL after mating; red blood cells (RBC): 1.95 ± 0.59 106/μL before mating, 2.25 ± 0.20 106/μL duringmating, 2.24 ± 0.35 106/μL after mating; hemoglobin (HGB): 10.11 ± 3.07 g/dl before mating, 11.02 ± 1.02 g/dl during mating, 9.79 ± 0.84g/dl after mating; hematocrit (HCT): 26.38 ± 8.04 % before mating, 28.73 ± 2.70 % during mating, 29.62 ± 3.77 % after mating; leucocyte(GRAN): 1.664 ± 0.81 103/μ before mating, 1.22 ± 0.29 103/μ during mating, 1.33 ± 0.36 103/μ after mating. The blood parameters obtainedfor female fish are as follows; white blood cells (WBC): 54.57 ± 4.86 103/μL before mating, 47.2 ± 8 103/μL during mating, 42.65 ± 7.11 103/μL after mating; red blood cells (RBC): 1.94 ± 0.18 106/μL before mating, 1.75 ± 0.33 106/μL during mating, 1.39 ± 0.33 106/μL after mating;hemoglobin (HGB): 10.17 ± 0.78 g/dl before mating, 8.89 ± 1.59 g/dl during mating, 6.74 ± 1.57 g/dl after mating; hematocrit (HCT): 26.18 ±2.07 % before mating, 22.44 ± 4.54 % during mating, 18.04 ± 4.03 % after mating; leucocyte (GRAN): 1.54 ± 0.47 103/μ before mating, 1.18± 0.26 103/μ during mating, 1.09 ± 0.22 103/μ after mating.
