HAEMATOLOGICAL EFFECT OF AQUEOUS EXTRACT OF EUPHORBIA TIRUCALLI PLANT LATEX ON SNAKEHEAD FISH, CHANNA PUNCTATUSSONAL SINGH, ANJANA BANSAL AND R.K. GOEL
The aim of this study was to asses the impact of aqueous extract of Euphorbia tirucalli plant latex on snakehead fish,channa punctatus. The median lethal concentraion(LC50) value of aqueous extract of Euphorbia tirucalli plant latex on Channa punctatus was 46.5 mg/L for 30-hours of exposure.The two different sub-lethal doses(20% and 40% of 30h-LC50) were administered to experimental fish for 30-hours and 60-hours exposure time. Some haematological parameters were analyzed to determine the influence of aqueous extract of Euphorbia tirucalli plant latex on the Channa punctatus. The range values obtained for the Total Erythrocyte Count (TEC), Eosinophils, Neutrophils, Monocytes, Haemoglobin Concentration (HbC) and Specific Gravity significantly lower,while Lymphocytes, Basophils, Erythrocyte Sedimentation Rate (ESR) and Mean Corpuscular Volume (MCV) significantly higher at both of sub-lethal doses(20% and 40% of 30h- LC50). Mean Corpuscular Haemoglobin Concentration (MCHC) values showed differently. Aqueous extract of Euphorbia tirucalli plant latex could lead to alterations in morphological parameters of the blood of Channa punctatus.
