It is one thing to select beautiful fish for your aquarium or pond, it is quite another to recognise diseases in your fish and also effectively combat them using the proper drugs. Many books are thick on text but thin on photographs; this book, by contrast, features 1.000 photographs of sick fish. After 25 year of reserach, Gerald Bassleer, an international authority in the field of fish diseases, han written this "New Illustrated Guide to Fish Diseases" as an extender and improved version of the popular "Colorguide of fish diseases" (1982). This book will enable the fish hobbyist: to recognise diseases in fish with the aid of a multitude of accurate photographs; to trace the underlying causes on the basis of a questionnaire; to familiarise himself with major fish diseases thorough concise descriptions written in plain language; to apply the correct treatment based on clear descriptions of practical uses of the latest medications. This book is a lavishly-illustrated aid to making the right diagnosis, not only for the aquarium retailer or pond centre, but also for the veterinarian´s or fish doctor´s practice.
