Abstract
Both chilling and chemical bath agents are inconveniently slow for anaesthesis of crayfish, generally having induction times of about an hour and recovery times of even longer. The use of electricity as a means of inducing narcosis or anaesthesia in crayfish was investigated using the yabby, Cherax destructor, as a test crayfish. It was found that under suitable conditions, narcosis of adult yabbies could be achieved within thirty seconds, and the duration of narcosis was about 10 minutes. The main factor limiting the application of DC electricity for narcosis was the water conductivity.
