Abstract Recently, the World Organization for Animal Health - OIE, through the Aquatic Animal Code, set recommendations for the welfare of farmed fish, mainly in transport, stunning and killing for human consumption. However, traditional methods of killing fish are not considered humanitarian. For example, immersion in ice or ice water is known with a method which causes a high degree of suffering as it does not cause an immediate loss of pain sensitivity. Hypothermia or immersion in ice water is used by most slaughterhouses in pre-slaughtering fish in Brazil. To consider slaughtering as humanitarian, the animal must undergo two processes: the first is the stunning leading to the loss of consciousness and then the bleeding to induce death. Thus, stunning is applied to induce unconsciousness and insensitivity to pain, which should be of sufficient duration to ensure death by bleeding. Electrical and percussive stunning are considered the most acceptable methods for fish stunning based on welfare and meat quality precepts. Currently, the best method to determine fish unconsciousness during the slaughter process is through Electroencephalography (EEG). In Brazil, studies on the use of EEG to assess fish unconsciousness during the slaughter process are absent. In this sense, the objective of this work is to determine the unconsciousness in Nile tilapia through Electroencephalography (EEG) in the process of stunning for electrical stunning, percussion and anesthesia pre-slaughter. | |
