Re: more info about shreckstoff Hi Bob,  I'm a student at California State University Sacramento and I am in the process of writing a paper for my ichthyology class. The topic I have chosen is "shreckstoff". I know this is a pretty general topic but I'd like to know a little more about it. If you have any information for me (i.e. additional web sites, personal research information, others that I can contact) about this mystery chemical it would be greatly appreciated.  Thanks a bunch!  Chrissy  <I have two or three old survey articles (popular/hobby press) archived on WWM re or that touch on these contagions... see here: http://wetwebmedia.com/AqSciSubWebIndex/SciAqIndex.htm  but I would definitely do a computer search (there's a piece on how to do these... but I suspect you are already familiar, facile with this technology) on the same Index.
