Fish radical on the left marks 鲌 as a fish species - specifically the culter, a slim silvery freshwater predator. The same radical anchors hundreds of species names like 鲤, 鲨, 鲸, all visually depicting a stylised fish.
Right side supplies both sound and a faint semantic hint: bái drifting to bó (vowel shift) and the silvery, pale belly of the culter matches 白's whiteness. Anglers know this fish for its bright, almost mirror-like flank.
