This book is the first of three on fish diseases and disorders. This volume provides a comprehensive review of the major diseases of fish caused by protozoan and metazoan parasites. Written by leading international authorities, it is aimed at zoologists and veterinary parasitologists, as well as those concerned with practical aquaculture and fish farming. Two further volumes (on viral, bacterial and fungal infections, and on non-infectious disorders) are planned for publication in 1996.
