skeeter96,
What you are describing sounds like lymphocystis. Here's a link to another thread in this forum from 2011 with additional info. http://www.crappie.com/crappie/ask-the-biologist/190008-el-dorado-crappie/
The fish should be OK to eat but obviously trim off affected areas and as always use your best judgement...if it looks odd, don't eat it!
Hope this helps!!
Craig
