They are trying to impose some law because hippies love a frog?!
Recall that kings once prohibited hunting of game in their kingdom so it would always be there for their dinner and sport. "...the Kings Deer..."
Look how that worked out for them? This will end the same... eventually.
We should respect limits (legal - for now - and just decency having grown up as a hunter/fisherman (not shooting a pregnant deer or keeping too small a fish)) as this protects inventories and natural order so I can kill them or their family later.
BUT!
If it is here; it is meant to be eaten. Hunt the stupid Frog and leave the fishermen alone. We'll be ok without the stupid frog.

to those that want to regulate everything...
