You seem to be missing the point - Is this a natural pond or is this a
suburban artificial pond. I assume you have such things there. I have
stated repeatedly that you would not want to put anything (mineral,
vegetable, animal) in any water that has either an outlet or an inlet to a
natural area (and that is recursive - so not to anything that anywhere down
the way has and outlet or inlet in to a natural area).

You simply wouldn't get permission......simple as that. The law here is
very strict on that account.

"It is an offence under the Wildlife and Countryside Act 1981 to release,
or allow to escape, any non-native animal to the wild in Great Britain
except under licence. The same offences apply in respect of certain
non-indigenous species, which have established resident populations in
Britain and which are listed in Schedule 9 of the Act."

The Signal Crayfish has decimated many rivers here, to the extent that
native varieties are in danger of disappearing. They have also badly
damaged the habitat of other river inhabitants.
