Аннотация

The blood of cottoid fishes has the lowest parameters that characterize the ability of heamoglobin to bind oxygen. Environmental characteristics of the species determine the morphological parameters of red blood cells and the structure of haemoglobins. In red blood cells of the Baikal yellowfin sculpin under the exposure of phenol, we revealed the damage of intracellular structures and a decrease in the number of active mitochondria by 60%.
