Quirky porcelain soup tureens were a popular product from Qing Dynasty China – you can find hogs heads, melons and geese in various museums. But this Pokemon-worthy, colourful fellow was made in the famed Jingdezhen kilns of China for the prominent Olza family of Spain (you can see the coat of arms on the cheek of the fish).
Domingo Esteban de Olza y Domezain, who commissioned this piece, was the first head of the Royal Company of the Philippines, which had a lucrative trade monopoly between Spain and its colony. We don't know if he actually ate fish soup in this fish tureen though 😀
You can see this specimen in the Peabody Essex Museum. https://www.pem.org/exhibitions/the-copeland-collection-chinese-and-japanese-ceramic-figures
