The ONLY way to know a fish is wild caught is if you see it come out of the river yourself.
Some fish are wild caught out of necessity, some because they're cheaper (bait fish) or won't breed in captivity.
Some are "wild caught" out of the desire to charge more or to garner some sort of reflected glory...
OP, YOU MAKE SOME GOOD POINTS! Be careful, though, you could be subjected to some personal attacks just for asking (if history is any indicator).
