In regards to the shrimp, I wonder what set them off? Surely someone didn't just wake up on the wrong side of the bed and think "I'm gunna go steal me some shrimp."
Not so sure. If they decided to legislate so that all non allowable imports were to be declared noxious the industry would not crumble. The pet shops, importers & chain stores would just continue on their merry way selling goldfish & livebearers etc. it is us, the specialist aquarium store that will suffer & we are not a strong power. If you doubt that they can do this sort if thing just look to the fishing industry & the huge changes made recently in respect to marine parks & recreational/commercial fishing bans. All this has been done despite the might of the rec fishing bodies combining to lobby against it.
We can't look to support from other groups either, they will probably be more against the cruelty of smuggling practices & perceived cruelty of keeping fish confined to tanks than in support Of us. Even the green element could be turned against us due to the threat from wild catching of stocks in 3rd world countries. I would not like to test them in court at all as a backfire would suck big time.
