Fish have become a popular companion animal and experimental model, as well as being farmed and fished for food. Surgical and invasive techniques are therefore widespread in this animal group. The focus of this research will be on fish anesthesia. Fish are frequently immersed in a variety of anesthetic agents. Correct dose can lead to effective anesthetic for acute operations as well as loss of consciousness during surgical procedures. Anesthetic agent and dose differ amongst fish species, and physiological characteristics such as body weight, physiological stress, and ambient circumstances further complicate things (e.g., water temperature). Combined with general anesthesia, which involves the use of two anesthetic drugs, has been shown to be effective in fish, but it is not widely utilized due to a lack of experimental confirmation. Recent research has looked into local anesthetics to see how effective they are at reducing pain and discomfort. In Koi Fish, the local anesthetic lidocaine is quite effective at reducing pain-related reactions. Clove oil, on the other hand, is less useful in decreasing pain. In order to establish acceptable anesthetic procedures, researchers need investigate extensive range of anesthetic medication in a variety of fish species
