title: Erythropoietic response and hematological parameters in the catfish Clarias albopunctatus exposed to sublethal concentrations of actellic.
abstract: Clarias albopunctatus fingerlings were subjected to sublethal concentrations (0, 0.3, 0. 5, 0.8, and 1.0microg/L) of actellic for 18 days in a static bioassay system. The hemoglobin, erythrocyte count, hematocrit, and leucocyte counts were affected by actellic. Compared with the control, the hemoglobin, hematocrit, and erythrocyte count decreased significantly (P<0.05) in the actellic-exposed fish. There was significant leucocytosis in the actellic-exposed fish. The fish exposed to actellic suffered macrocytic anemia. The changes in the hematological parameters were concentration dependent except in leucocyte counts.
