UNASSIGNED: The aim of this study was to compare physiological responses in @entity30721 ( @entity30721 ) induced by @entity1875 and @entity3158 anaesthesia. Two procedures were applied during the experiment. In procedure I, blood samples were collected immediately after exposure (1, 2, 5, 10 min) to the anaesthetic. In procedure II, fish were exposed to the anaesthetic for 10 minutes and then were moved to anaesthetic free water. Blood was sampled after 5, 10, 20 or 30 min of recovery time. Gasometrical and biochemical analyses were performed on collected blood. In @entity3158 anaesthetized fish strong @entity520 was revealed. The drop of the HCO3-/ @entity3158 ratio, from 28:1 in control fish up to 4:1 in @entity3158 anaesthetized ones, proved that the compensation mechanism is not capable of preventing @entity520 during @entity3158 anaesthesia in @entity30721 . In contrast, only moderate, @entity12906 occurred in sturgeons anaesthetised with @entity1875 . @entity520 during @entity3158 anaesthesia was followed by a fourfold increase of @entity3265 level in the blood. @entity413 level, increasing only during recovery time, indicates that a secondary stress response occurred when awareness of anaesthetized fish had been restored.
