Not sure how that works. 'Tilapia' isn't a fish. Its 'any whitefish'
tilapia are cichlids, and are not part of the old definition; not sure if the definition has changed
For comparison, there are 8 species of salmon. We eat maybe two of them.
All of which are cichlids.
That's a long way away from "any whitefish".
"Whitefish" most commonly refers to cod and pollock, not tilapia.
And we eat every species of salmon, not just two.
