Abstract: The effect of <i style="">Spirulina </i>supplementation on reduction of copper toxicity based on food utilization, phosphatases activities and selected haematological parameters was studied in a freshwater cultivable fish <i style="">C. mrigala. </i>Metal concentration in medium, body tissues and fecal matter was also analysed. Sublethal exposure of <i style="">C. mrigala </i>fed <i style="">Spirulina </i>– free diet significantly reduced the consumption and growth rates, phosphatases activities and haematological parameters. However, the above parameters enhanced in the copper exposed fish fed with <i style="">Spirulina </i>supplemented diets. A significant positive correlation was obtained for the relationship between supplementation of dietary <i style="">Spirulina </i>and copper defecation through feces. Among the doses of <i style="">Spirulina </i>supplementation, 6% addition has been considered optimum for <i style="">C. mrigala</i> since this dose produces maximum elimination of copper from the body and feces and better improvement on growth, phosphatases activities and haematological parameters.
