. Oxygen regime of skeletal muscles in marine fishes and mechanisms of its functional correction at different state of organism and environmental conditions were investigated. Low oxygen diffusion in fish muscle tissue in comparison with other vertebrates was observed. This phenomenon was shown to be the main cause of low level of tissue РО2 and small efficiency of О2 utilization. New kinds of hemic and circulating hypoxia were distinguished. Diffusion and hypodynamic hypoxia states were studied for the first time. The classification of hypoxia states for hydrobionts was proposed. The mechanisms of fast and long-term correction of tissue РО2 in fish were investi-gated.
