Haematological characteristics in fish changes in response to environmental conditions and thus could serve as indicators of sub lethal environmental stress. Exposure of snow trout, Schizothorax richardsonii to different water pH (5.0-9.0) for 24 h resulted in alteration in haematological and enzymological parameters. The fishes showed obvious signs of stress at pH 5.0 as indicated by their behavioural changes. Blood haemoglobin (Hb), red blood cells (RBC) andpacked cell volume (PCV) were higher at both extremes of pH, but significantly (p<.05) higher at lower pH than control group at pH 7.0. Likewise, serum enzymes viz. Lactate dehydrogenase (LDH), Glutamic oxaloacetic transaminase (GOT), Glutamic pyruvate transaminase (GPT), Acid phosphatase (ACP) and Alkaline phosphatase (ALP) exhibited elevated levels during acid stress. Conversely, protein concentration fell considerably in fishes exposed to low pH.
