Changes in Hematological Parameters of Cichlasoma dimerus (Teleostei, Perciformes) Exposed to Sublethal Concentrations of 4-tert-Octylphenol

Stress response involves various physiological changes, including alteration in hematological parameters closely related to the response of fish to the environment. 4-tert-octylphenol (OP) is one of the worldwide-used surfactants and can pollute the aquatic environment, both marine and freshwater. P...

Experimental groups consisted of control (ethanol 0.005 %), OP 150, and OP 300 μg/L. OP caused hemodynamic stress in C. dimerus, which lead to normochromic and normocytic anemia, as well as erythrocytic pathologies such as a significant increase in erythroblasts and amitotic erythrocytes.
