Fishes are largely used for the assessment of aquatic environment quality and are accepted as bio indicators of environmental pollution. Researches of biochemical response against to spontaneous elements furnish worthwhile information on the influence of the exterior environment on the internal physiology of fish. For monitoring fish health haematological parameters have been perceived as one of beneficial measure. In the current research the fresh water fish, Channa striata, haematological profile was studied. Fishes were categorized into four groups and each solitary group of fish subjected to ۱۰ ppm concentrations of SO۲, NO۲ and H۲S after every ۱۰ days interval for the span of ۳۰ days. One group of fish was maintained as control without any treatment. After experimental period specimen were allowed for collection of blood to test the haematological profile. In haematological profile, stipulated blood parameters influence is discerned on RBC count, WBC count, Hb, and PCV furthermore on Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC). The industrial emissions in particular SO۲, NO۲ and H۲S considerably declined the value of RBCs, Hb, PCV, MCH, MCV, MCHC, while on the contrary WBC count elevated discretely with H۲S treatment when compared with other gaseous pollutants employed in present experiment. To conclude, all the industrial emissions engendered haemotoxicity in fish. The fishes exposed to SO۲, NO۲ and H۲S also allowed to check biochemical parameters i.e., moisture, total ash, rehydration ratio, total sugars, proteins, total carbohydrates, crude fiber and fat content in fresh and dried biomass of respective treatments against to control treatment. The obtained results concluding that the emissions such as SO۲, NO۲ and H۲S not only shown impact on haematological profile it also decreased biochemical parameters of fresh water fish Channa striata.
