The rapid increase in fish farming has led to increased problems in disease. There is thus now a great need for students and practising veterinarians to master the basic principles of their work as it specifically relates to these aquatic animals. This text ensures that such basics are available in one practical and readable handbook. This book is divided into two sections, the first of which deals with basic principles and approaches to aquaculture. The second section contains specific information which is of use to veterinarians working in particular regions of the world. Fin fish, shrimps and ornamental fish are covered in detail. This handbook is the ideal text for the land-based veterinarian who wishes to test the waters of aquatic animal practice.
