It is a well known fact that blood parameters act as reliable indicators of fish health. In present studies, we have focused on hematological profile of different fish species. Haematological changes i.e. shape change of erythrocytes, thrombocytes and lymphocytes etc. are well known for their clinical value in prognosis and diagnosis. As hematopoiesis between fish and mammals is highly conserved, the fish can, thus, serve as an attractive model to study hematological changes in response to external environment stressors. Thus, the study of piscian haematological indices can not only be effectively used in fish health management but also in formulating mitigation measures against aquatic pollutants as well.

Linear alkylbenzene sulphonate (LAS), an anionic surfactant, is the most widely used active component in most of the laundry and cleansing (L& C) compounds. Improper and untreated discharges of domestic and industrial efuents, which largely contain adequate amount of LAS, frequently pollute both lentic and lotic aquatic habitats and adversely affect their ecological prole. Both aquatic ora and fauna are concomitantly exposed to xenobiotic stress on account of surfactants which have registered a spurt both in their production and consumption, globally. Fishes are the worst sufferer of detergent pollution as they lie on top of trophic level in an aquatic food chain. Blood values of shes are sensitive indicators of aquatic pollution as is evident by haematological anomalies in the sh Heteropneustes fossilis exposed to sub-lethal fractions, 1/2, 1/3, 1/4 of 96 h LC of LAS along with its 96 h LC .In present studies, haemoglobin (Hb) and absolute 50 50 erythrocyte count (AEC)were recorded with a decreasing while total leukocyte count (TLC) with an increasing trend in a concentration dependent manner in all exposure groups as compared to unexposed control group. The alterations in the above haematological parameters of the sh can, thus, be used as sensitive indicators of contamination of aquatic regimes on account of LAS.
