Thank you very much for your help earlier this year. I wonder if you might be interested in this paper I saw dealing with low salinity resisitant Cryptocaryon, and the genetic and morphological variability of C. irritans in general. There is some useful material here I think...

A google search for this or low salinity crypt will reveal an abstract. If you want a full pdf I have one for private use and you can use email wayox at statoilhydro.com. I do not see how to directly link it into this message?
