Description

Hematological changes in common carp during the recovery period from molinate anemia were studied. Anemia was inducced by 14-day exposure to molinate (0.32 ppm). Anemic fish were transferred to, and maintained for 11 weeks in, clean water. Hematological examinations were undertaken 8 times at one and/or two week intervals. The initial RBC, Hb and Ht values were 218-257×103, 1.25-1.33g and 4.0-4.9%, respectively. The RBC recovered within 5 weeks, but the recovery of Hb and Ht was retarded. A considerable decrease of MCHC, MCV and MCH was observed during the first 3 weeks. While MCHC recovered within 7 weeks, MCV and MCH did not recover sufficiently during the 11-week observation period. Based on these fingings, molinate anemia was categorized as a hypochromic microcytic anemia, characterized by a high percentage of immature erythrocytes. In leucocytes, a remarkable increase in the number of spindle cells was noted.
