Cutting down rain forests, dynamite fishing is illegal it's a matter of country's having the resources to implement . On the plus side at least the fish isn't going to end up on centre piece at a Chinese wedding. I've had to import an Asian aro though the cities system which is costly the difference being it came from an aro farm, but still technically removing a fish from its country, although if there was no financial gain these farms wouldn't exist so the numbers would be greatly reduced. If you can keep a native fish which other wise might be caught and sold on black market in asia good luck to you.
