Why is Kujo Jotaro called "a big fish seller"?

Because a subtitle group in ova called Er Qiao Seitaro translated Seitaro into A Qiang, and then Seitaro became an oceanographer. So it's called "selling fish".

Kujo Jotaro, the protagonist in the third cartoon Kujo Jotaro, is the great-grandson of Jonathan Joesta in the first cartoon, the grandson of Joseph Joesta in the second cartoon, the nephew of Oriental Zhang Zhu in the fourth cartoon, the great-grandson of Gioruno Jobana in the fifth cartoon and the father of Xu Lun in the sixth cartoon.
