title: Epidemiological approach to aquatic animal health management: opportunities and challenges for developing countries to increase aquatic production through aquaculture.
abstract: Aquaculture appears to have strongest potential to meet the increasing demands for aquatic products in most regions of the world. The world population is on the increase, as is the demand for aquatic food products. Production from capture fisheries at a global level is levelling off. Potential contributions from aquaculture to local food security, livelihoods and nutrition can be highly significant, especially in many remote and resource-poor rural areas. One of the major constraints to aquaculture production is the losses due to diseases. Over the decades, the sector has faced significant problems with disease outbreaks and epidemics which caused significant economic losses. The use of sound epidemiological principles and logical and science-based approach to identify and manage risks comprise two of the most important components of an effective biosecurity program. The maintenance of effective biosecurity in aquaculture is becoming more and more essential. There will be more demand for aquatic animal epidemiologists as well as epidemiological tools/resources in the region. The use of epidemiology will significantly improve health management, risk analysis and disease control. Although there are clear limitations and complications in the use of epidemiology for controlling aquatic animal pathogens, some positive results have recently emerged from a series of studies and trials to control diseases affecting the small-scale shrimp farming sector in southern India. This paper summarises the results of one such study which emphasizes the significant benefit of close collaboration with farmers, both individually and as groups, and capacity and awareness building among them and the importance of understanding the risk factors and implementing better management practices.
