In by email from Jax in New Zealand:

I really wanted to answer a query about the N.Z. Mud Snail. Some one who fishes Lees Ferry asked about the Snails.

The only info I managed to get was from :- [url=http://www.esq.montana.edu/aim/mollusca/nzms/status/html.:1d577]www.esq.montana.edu/aim/mollusca/nzms/status/html.[/url:1d577] not sure you can publish it but you would know better than me.

Strange I had to go the U.S.A. to find out about a snail on my back door step. No Info here from Fish and Game. I have updated them"G" Regards jax
