With an ever increasing demand for seafood that cannot be met by capture fisheries alone, growing pressure is being placed on aquaculture production. However, infectious diseases are a major constraint.  Infectious disease in aquaculture: prevention and control brings together a wealth of recent research on this problem and its effective management. Part one considers the innate and adaptive immune responses seen in fish and shellfish and the implications of their responses for disease control. The specific immune response of mollusks and crustaceans is considered in depth, along with the role of stress in resistance to infection. Part two discusses advances in disease diagnostics, veterinary drugs and vaccines.  Chapters in this section explore quality assurance, the use and effects of antibiotics, anti-parasitic drugs in aquaculture and developments in vaccination against fish bacterial disease.  Part three focuses on the development of specific pathogen-free populations and novel approaches for disease control. These approaches include specific pathogen free shrimp stocks, developments in genomics and the use of bacteria and bacteriophages as biological agents for disease control.
