Present study was conducted to assess the haematological profile of Channa marulius from hatchery and riverine populations. Blood samples were collected by caudal vein puncture. Significantly higher values (p ≤ 0.05) were recorded for various blood indices in hatchery populations as compared to those of riverine sources. Observed values of haematological parameters in hatchery populations were: Erythrocytes 4.90×10⁶ cells µL^-1, eosinophils 4.06 %, monocytes 5.53 %, haematocrit count 28.86 %, haemoglobin content 5.385 gdL^-1, platelet distribution width 6.91 fL, red blood cell distribution width 23.83 fL, Procalcitonin 2.37 µL, mean corpuscular volume 7.87 fL and large platelet concentration ratio 14.64 %. In riverine populations, significantly higher values (p ≤ 0.05) for leucocytes count 5625×10³ µL^-1, mean cell haemoglobin 32.75 pg, mean corpuscular haemoglobin concentration 43.66 gdL^-1 and mean cell volume 171.90 fL were observed as compared to those of hatchery populations. Conversely, non-significant (p ≥ 0.05) differences were observed with elevated values for neutrophils (14.042 %) in riverine fish populations as compared hatchery samples (13.896 %). Lymphocytes and platelets counts were 17.344 % and 33.742×10³ µL^-1, respectively in hatchery populations whereas in riverine populations these were 13.764 % and 33.896×10³ µL^-1, respectively. Physico-chemical parameters of sample water were observed to be in safe range throughout the study period. The observed variation in haematological profile between both groups is due to different inhabiting conditions that exert direct impacts on fish haematology.

南美白Chan的孵化场和河流种群血液学特征的比较评估

目前的研究是从孵化场和河流种群中评估Channa marulius的血液学特征。通过尾静脉穿刺收集血样。与河源相比，孵化场人口的各种血液指数记录的值明显更高（p≤0.05）。孵化场种群的血液学参数观察值为：红细胞4.90×10 ⁶细胞µL ^-1，嗜酸性粒细胞4.06％，单核细胞5.53％，血细胞比容计数28.86％，血红蛋白含量5.385 gdL ^-1，血小板分布宽度6.91 fL，红细胞分布宽度23.83 fL，降钙素原2.37 µL，平均红细胞体积7.87 fL，大血小板浓缩比14.64％。在河流人口中，与白细胞相比，白细胞计数5625×10 ³ µL ^-1，平均细胞血红蛋白浓度32.75 pg，平均红细胞血红蛋白浓度43.66 gdL ^-1和平均细胞体积171.90 fL显着更高（p≤0.05）。孵化场人口。相反，与孵化场样本相比，河流鱼类种群中的中性粒细胞升高（14.042％），差异无统计学意义（p≥0.05）。淋巴细胞和血小板计数分别为17.344％和33.742×10 ³ µL ^-1在孵化场种群中分别为13.764％和33.896×10 ³ µL ^-1。在整个研究期间，观察到样品水的理化参数均处于安全范围内。两组之间观察到的血液学特征差异是由于不同的居住条件直接影响了鱼类的血液学。
