From TPWDs commercial fishing regs:
Quote:
*NOTICE: To be lawfully imported, sold or
purchased in Texas, bass of the genus
Micropterus, crappie, flathead catfish, red
drum, striped bass, white bass or a hybrid
of any of these fish must be farm raised
and fed a prepared feed containing 20% or
more of plant protein or grain by-products
as a primary food source.
Either the guy was lying to you about them being wild caught, or breaking the law... Either way, it seems shady.
Was it a fillet, half shell, or whole fish? They may also be trying to pass something else off as redfish (black drum most likely). It's pretty common for other snappers to be sold as red snapper.
