About
The character "鳙", whose traditional form is "鱅", has consistently denoted the bighead carp, a freshwater fish, and its formation is based on the phono-semantic principle with the radical 鱼 (simplified from 魚) indicating the semantic field of fish and the component 庸 serving as a phonetic element to suggest pronunciation. The structural evolution from the traditional to the simplified form involved only the graphic simplification of the semantic radical from 魚 to 鱼, while the phonetic component remained intact, and the character's meaning has not deviated from its original reference to this specific carp species over time.
