Abstract

Blood parameters of Siberian roach affected by Haff disease from Lake Kotokelskoe (Lake Baikal basin) are presented for the first time. In 2008, the lake experienced an ecological catastrophe: an outbreak of Haff disease occurred for the first time in Eastern Siberia. After the onset of toxicosis, the individuals showed signs of dyserythropoiesis and disturbances in leukopoiesis—degenerative changes in erythrocytes and leukocytes, the development of anemia, inflammatory processes, and a decrease in the number of lymphoid cells, initiated by a combination of negative environmental factors, including, probably, the impact of cyanobacterial products. A comparison of the hematological parameters of roach from the transformed lake with those of roach from a healthy area (Chivyrkuisky Bay of Lake Baikal) 6 years after the outbreak of Haff disease showed the presence of destabilization processes in the immune and hematopoietic systems.
