As others have stated, it's much easier and believable to export small fish / fry.
I'm much more suspicious of vendors who claim to be exporting large quantities of adult fish from the wild. The logistics of it are just that much more complicated (and expensive), especially if the fish are (allegedly) being sourced from someplace (i.e. not Peru) where commercial tropical fish exporter aren't established.
It also makes sense to differentiate between hobbyist collecting trips and commercial operations.
Trips by hobbyists have introduced a few wild fish into the country (from places really off the beaten path)...some F1s (mostly sourced from the folks who actually collected them or someone else in the hobby)...and lots of F2+ offspring from those. It's great to have new fish in the hobby and it's really important to maintain "pure" lines (i.e. with provenance to the few wild fish collected at a particular locale by known people), whether F1 or F10.
I've yet to hear details around commercial-scale export operations of fish from anywhere in the New World other than Peru (are there others?). Huge numbers of fish from (or out of) Peru make sense (the topic of fish from Brazil being exported are Peru is another topic). Other places...not so much (without some sort of explanation or proof.)
Finally, as Mo said, there are a lot of people re-selling "wild" fish...and fewer actually collecting them. We can argue about the level of responsibility that folks have in re-selling fish that others have told them are "wild", but in the end it's caveat emptor (buyer beware).
