Koi Health and Disease - Erik L. Johnson, D.V.M. 

If there is a book that a Koi keeper must have it's this book.  EXCELLENT FOR BEGINNERS...Without sacrificing plenty of depth where needed... a Koi keeper's bible!
This book goes into extreme detail and gives you STEP by STEP instructions on how to save fish lives under a hundred different conditions.

You'll find it very impressive with its content and the excellent balance between practical and technical information. 

There is a great deal of information on parasites, bacterial pathogens, fungal infections, and viral infections. Primary and alternative treatment protocols are very well presented. Microscopy is well detailed.
