Etymology
About
The character "鲌", with its traditional form "鮊", is structured with the semantic component "鱼" denoting fish and the component "白" serving a phonetic role while historically associated with the concept of whiteness. Etymologically, it was used as a general term for several types of light-colored freshwater fish, but over centuries its application has narrowed to specifically refer to certain species within the genus Culter, such as the topmouth culter, reflecting a shift from a broader descriptive category to a more defined taxonomic identification.
