Cyprinids rank as one of the most commercially important groups of freshwater fishes and are exploited for many purposes; as a human food source, especially in Europe and Asia; as sport fish; and as ornamental fish for ponds and aquaria. Certain species are also cultured as bait fish and several of the small cyprinids such as the zebra fish have become internationally accepted laboratory models for toxicology testing and molecular research. A thorough understanding of cyprinid health and diseases is fundamental to the successful management and exploitation of these fishes for freshwater fisheries, pisciculture and ornamental productions. This practical guide to disease diagnosis, prevention and control includes numerous colour plates and covers a comprehensive array of diseases - infectious and non-infectious - of cultivated and wild cyprinids.

The prominence of the carp group of fish is widely recognised in three important economic areas: food production, recreation and the ornamental market. Carp species thus represent over 50% of world fish production and are vital to the economic stability of several countries and global regions. It is therefore crucial that the health of these cultured aquatic species is properly considered and maintained to ensure the sustainability of production and recent disease epidemics, for example grass carp reovirus infections in China and koi herpesvirus disease in Asia and Europe, have caused widespread and devastating effects on the aquaculture industries. This book thus examines how the diseases of carp species can be properly identified, monitored, treated and prevented. It specialises on the most prominent globally occurring carp species, such as Cyprinus carpio (common carp), the Carassius species, and the carp species that predominate in Europe and Asia, such as Ctenopharygodon idellus (grass carp), Hypophthalmichthys molitrix (silver carp), and Hypophthalmichthys nobilis (bighead carp). It also looks at the more specialised production of certain species, for example Catla catla (Catla) and Labeo rohita (Roho), in the Indian subcontinent. With the continuing importance of the carp group of fish, this user-friendly book presents a practical approach to disease diagnosis and treatment that covers both infectious and non-infectious diseases. The detail included about disease, clinical signs and the application of control strategies, such as management practices, therapeutics or vaccination, is an effort to considerably improve general fish health and welfare.
