Haematological studies of climbing perch (Anabas testudineus Bloch)

Some blood parameters of the climbing perch (Anabas testudineus Bloch) i.e. red (RBC) and white (WBC) blood cell count, percent haematocrit (HTC), hemoglobin, plasma protein as well as hepatosomatic index (HSI) were studied. There were no statistically significant difference (p>0.05) in average body weight and length of fish from the earthen pond and net cage culture, which were 16.85±1.46 g and 16.24±2.42 g, respectively, for the weight and 10.02±0.25 and 9.74±0.37 cm, respectively, for the length. Haematologicalstudies revealed that RBC, WBC including percent HTC levels of the fish from earthen pond and net cage were not significantly different (> 0.05). Whereas hemoglobin and serum protein concentration of the fish sampling from net cage were higher than those sampled from the earthen pond (p<0.05), with value of 12.21± 0.91 g/dl and 11.12±0.85 g/dl for hemoglobin and 4.61±0.50 mg/dl and 3.87±0.62 mg/dl for serum protein, respectively. HSI of the fish cultured in the earthen pond was significantly (p<0.05) higher than that of fish reared in net cage, with value of 1.93±0.12% and 1.66±0.12%, respectively.
