在对鱼类等水生动物进行捉拿、运输、外科手术等操作过程中,常因捕捞的伤害或因挣扎,造成缺氧和细菌或霉菌的感染,而引起死亡,为减少这些危害常需对鱼进行麻醉以降低动物的应激反应。电麻醉是一种比较新型的麻醉方式,主要的优势是它在感应时间和恢复时间上超越了化学麻醉,化学麻醉往往药品比较昂贵,麻醉耗时较长,并且麻醉对鱼类的生理和行为影响 In the handling of aquatic animals such as fish during their operation such as catching, transporting, and surgeries, they often cause fishing deaths due to fishing injuries or struggles, leading to hypoxia and bacterial or fungal infections. To reduce these risks, fish Anaesthetize to reduce stress response in animals. Electrical anesthesia is a relatively new type of anesthesia, the main advantage is that it exceeds the chemical induction of induction time and recovery time, chemical anesthesia is often more expensive drugs, anesthesia takes longer, and the effects of anesthesia on fish physiology and behavior influences
