Magnesium chloride as an anaesthetic for cephalopods.
Magnesium chloride is an effective anaesthetic and narcotizing agent for cephalopod molluscs. Individuals belonging to five genera (decapod and octopod) were anaesthetized and subsequently revived at temperatures ranging from 13 to 22 degrees C. At no stage of anaesthesia does MgCl2 appear to cause any trauma. There is evidence that MgCl2 acts centrally on the nervous system to induce anaesthesia. This salt, cheap, readily available and convenient to use, is recommended over urethane or ethanol as a suitable anaesthetic or narcotic for use with cephalopods.
