Comparative analysis of hematological parameters of Schizothorax niger and Schizothorax esocinus
Aijaz Ahmad Bhat
The blood of fish from various water bodies was screened for various hematological parameters. Before the collection of the blood sample, the length and weight of fish were also noted. During the present study mean weight varied from 95g to 260 g. The mean weight at Beerwa of Schizothorax niger was 190±0.86, at Akad was 293±110.5, at Kokernag was 262.5±53.93.Where as that of S. esocinus was 214.08±2.28, 221.2±80.92 and 267.8±119.3 respectively.The mean hemoglobin value in the fish varied from 9.65±0.91 (lowest) to 10.43±0.10 (highest). S.niger reared at Beerwa has shown 10.03±0.3, at Akad it was 9.16±0.63 and at Kokernag it was 8.78±0.31. Where as S.esocinus has shown 10.43±0.10,9.28±0.52 and 10±0.12 respectively.The RBC value of the spring fish was found to be comparatively lower than the RBC value of fish from stream. The mean RBC value was 1.14±0.02. S.niger reared at Beerwa has shown 1.14±0.02, at Akad it was 2.03±0.21 and at Kokernag it was 1.71±0.26. Where as S. esocinus has shown 137±0.01, 2.056±0.17 and 2.18±0.12 respectively. The mean packed cell volume was found to be 21.09±0.81 (lowest), while it was 26.61±0.55 (Highest). S. niger reared at Beerwa has shown 21.09±0.81, at Akad it was 28.2±2.65 and at Kokernag it was 2.83±0.50. Where as S.esocinus has shown 26.61±0.55, 29.0±2.35 and 31.3±2.05 respectively. Leucocytes are the defense cells of the body which provide protection to the organism against environmental as well as anthropogenic stress. The WBC count of river fish was higher than the fishes collected from other water bodies. The mean WBC count in the fish was 55.10±2.51. S. niger reared at Beerwa has shown 5.10.09±2.51, at Akad it was 4.67±0.36 and at Kokernag it was 2.83±0.50. Where as S. esocinus has shown 40.34±1.07, 2.39±0.65 and 2.12±0.59 respectively.
