In part I think so with regards to fish. The fish are coming from different breeding houses, and a fair amount may still be wild caught specimens. So definitely a *possibility* at least.
As for equal rights for a hobbyist keeping allowed animals versus someone who wishes to introduce an entirely new species/animal, well not really in the same ball park IMO.
And I don't agree with the repeated statement: only keeping one bird so it can't breed, or only letting in a dozen birds. What? That is nonsensical with respects the topic of introducing an entirely new species IMHO.
I'm bored with this argument now. It is not like our discussion is actually going to change each others point of view, or change the outcome of any applications.
Lets go have a beer instead, my shout.
