Sedation and slaughter of Atlantic salmon (Salmo salar, L.) with carbon monoxide, and a possible regulatory role of neuroglobin
Until recently CO2 has been utilized as an anesthetic method before gill cutting of Norwegian Atlantic salmon farmed fish. From 1. July 2012 this is no longer permitted in Norway since it causes strong aversive reactions and severe stress to the animal. In the search for alternative methods for seda...

Until recently CO2 has been utilized as an anesthetic method before gill cutting of Norwegian Atlantic salmon farmed fish. From 1. July 2012 this is no longer permitted in Norway since it causes strong aversive reactions and severe stress to the animal. In the search for alternative methods for sedation and anesthesia carbon monoxide (CO) has gained interest. In our project, studies demonstrate that CO treatment has a positive effect on product quality and animal welfare. The use of CO in slaughtering, processing and packaging of muscle foods has been reviewed. The present thesis focuses on how sedation of Atlantic salmon with CO affects animal welfare and quality of fish when used as an alternative method prior to anaesthetization.
