The Materia Medica (Bencao) records: There is the yuezuo in the rivers, which resembles a wild duck but is larger, with red eyes. It is likely that zhuyu is a phonetic shift of yuezuo.

Furthermore, Shuyu is also the name of a palace. History of the Former Han (Qianhan Shu), Annals of Emperor Xuan: The Emperor visited the Shuyu Palace. The Notes on Sounds and Meanings (Yinyi) explains: Shuyu is a type of water bird. It resembles the jiaojing bird, and its likeness was depicted on the palace, which is why it was named accordingly.
