Electronarcosis, also known as electric narcosis or stunning, is a process used to immobilize fish before slaughtering. However, there are numerous other terms that can be used in place of electronarcosis depending on the context. These synonyms include electric shock, stun, anesthesia, paralysis, sedation, and numbness. These terms are often used interchangeably, particularly in the medical and scientific fields. Regardless of the word used, the purpose of electronarcosis remains the same - to render the animal immobile and reduce any potential suffering or stress during the process of slaughter.
