Diseases of Fishes: Bacterial Diseases of Fishes and Identification of Fish Pathogenic Bacteria

Description

Fish is considered as principal source of protein for many people in different parts of the world, particularly in developing countries. Though most fish are caught from nature, fish farming is now making a significant contribution to total fish production. However, the conditions of the aquaculture often results in a higher incidence of fish disease is of immediate practical relevance as well as of scientific interest. Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth. If pathogens breach these defences, fish can develop inflammatory responses that increase the flow of blood to infected areas and deliver white blood cells that attempt to destroy the pathogens. Disease is a prime agent affecting fish mortality, especially when fish are young. Interacting factors result in low grade infection becoming fatal diseases.
This book addresses infectious diseases of fish and their disorders that arise due to viruses bacteria and fungi. it is well written and contains updated information that reflects new developments in the field.
