Fish Disease

Fish Disease: Diagnosis and Treatment, Second Edition
provides thorough, yet concise descriptions of viral, bacterial,
fungal, parasitic and noninfectious diseases in an exhaustive
number of fish species. Now in full color with over 500 images, the
book is designed as a comprehensive guide to the identification and
treatment of both common and rare problems encountered during the
clinical work-up. Diseases are discussed following a systems-based
approach to ensure a user-friendly and practical manual for
identifying problems.

Fish Disease: Diagnosis and Treatment, Second Edition is
the must-have reference for any aquaculturists, aquatic biologists,
or fish health specialists dealing with diagnosing or treating fish
diseases.
