Fish Disease. Diagnosis and Treatment

Description

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.
