Major viral and bacterial disease problems in shrimp culture

Abstract

Major disease problems particularly viral and bacterial in origin have resulted in significant decline in the production of farmed shrimps worldwide.

The major diseases of viral and bacterial origins are listed and described. Innovations being applied to prevent and/or minimize their effects are enumerated.

The paper suggests a broad outlook of shrimp disease by considering not only the etiological causes but also the epidemiological approach. Attempts to produce disease-free fry are still expensive and cannot be applied widely in commercial farms. The aim is to attain sustainable shrimp farming.
