Research on the Application of Fishery Anesthetic MS-222 and Eugenol in China

As a large aquaculture industry country, China has been producing the world’s largest number of aquaculture production for many years. In the operation to aquatic animals such as fishing, transportation, artificial propagation, individual marking, internal anatomy and external morphological measurement, etc., aquatic animals will produce strong stress reactions, such as mucus secretion, jumping and struggling, which seriously hamper the smooth development of related work and cause some harm to fish. The scientific and rational use of anesthetics can significantly reduce the stress response of fish, reduce the damage to fish, and facilitate manual operation.
