Blood parameters of Siberian roach affected by Haff disease from Lake Kotokelskoye (Lake Baikal basin) are presented for the first time. In 2008, the lake experienced an ecological catastrophe: for the first time in Eastern Siberia, an outbreak of Haff disease occurred. After the onset of toxicosis, the studied 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. 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.
