要約

It was shown that exposure of fish (12 marine species under study) to urethane in concentration of 1.5-5.2 g per liter of the ambient sea water caused development of three successive states. These states (stages of anesthesia) are designated by the author as quiet, excitement and deep anesthesia. The quiet period was observed during 1.5-3.0 hours. The fright reaction was absent and the fish physiological state was stable. The excitement period coincided with the loss of coordination and intensification of metabolic processes. At the period of deep anesthesia, the loss of mobility in fish was registered in parallel with progressive decrease of respiration and heart rate and development of tissue hypoxia. The dependence of effective urethane concentrations on water temperature, salinity, O2 content, and motor activity of fish was under study as well.
