refers to medicines specially used in fisheries to ensure the healthy growth of aquatic animals and plants. Therefore, its scope of application is limited to aquaculture, and the substances used in capture fisheries and fish processing industries are not included in the scope of fish medicine.
Modern aquaculture fisheries are divided into two major parts: fish, shrimp, shellfish, turtles, turtles and other aquatic animals, and aquatic plant species such as laver, kelp and other aquatic species. Therefore, fish medicine is also divided into two parts: aquatic plant medicine and aquatic animal medicine, which can also be called aquatic medicine.
Fish medicines are usually classified according to pharmacological effects. However, fish medicine is basically classified according to the purpose of use due to insufficient pharmacological research.

Fish medicine is an important weapon for humans to fight against aquatic animal and plant diseases, insects, and pests, and is also an important means to improve the health of aquatic animal and plant bodies and promote growth and development. The purpose of applying fish medicine is to ensure and increase fishing output.
