The acute toxicity bioassay of textile industrial effluent (TIE) was carried out by the probit analysis method. The 12, 24, 48, 72 and 96 h LC50 values were obtained as 56.23 %, 28.84 %, 22.38% and 16.59% respectively. LC50 values were significantly decreased with increase in effluent concentration. The safe value was found to be 32.88 %. The experimental fish C.batrachus exhibited stressful behaviour which increased with toxicant concentration. Due to acute toxicity of textile based industrial effluent, experimental fish C. batrachus expressed high secretion of mucus, uncoordinated and tailfin movement, surfacing, loss of buoyancy, escaping tendency, hyperactivity, and discolouration of the skin. Mortalities were observed in all treatments except control. The haematological analysis was also carried out in experimental fish C.batrachus exposed to various periods in textile-dyeing effluents. Haematological data were evaluated for parameters such as Hb, RBCs, WBCs, PCV, MCH, and MCHC of the test species. The alterations of these parameters have been discussed. So it can be concluded that the TIE is toxic to fishes and aquatic organisms.
