Hi Anorwood
Joking aside
Richard (Mabe Brazil) is raising some freshwater mollusks and has many posts here on the subject. If you are interested in the freshwater pearl mussels, he has learned a lot. I have long wanted to raise some freshwater mussels in a backyard pond- but I am still in the planning stages.
I am really not sure if you can buy baby sea pearl mollusks on the market, at least yet, although there is a small contingent of people trying to raise freshwater mollusks domestically, that is, in large outdoor tanks, I think most of efforts I have heard about would be under the auspices of a university extension service.
I joined the
unio listserve several months ago. This list is supported by a network of freshwater mollusk scientists in the US. They are especially interested in having members who are raising mollusks in larger,outdoor tanks, not living room aquariums.
This list itself is rather dry, but I think one who was serious could get a lot of help and suggestions from indiviual members.
Freshwater mollusks are often described as the lungs of the river they live in and they are studied because they reflect the general health of the water they grow in.
This is a huge subject and I have tried to collect resources about different states and what steps they are taking for river health. you will find these under the resources section.
