Book (series)Checklist of the parasites of fishes of Bangladesh 2002
Also available in:
No results found.This checklist is part of the FAO's continuing effort to address the need for information on the occurrence of diseases and pathogens of aquatic animals in the Asia-Pacific Region. A previous checklist, published as FAO Fisheries Technical Paper No. 369, has summarized the parasites of fishes of the Philippines. These documents support the FAO/NACA regional strategy for the Development of Health Certification and Quarantine Guidelines for the Responsible Movement of Live Aquatic Animals in As ia, a programme involving 21 Asian nations, FAO, the Network of Aquaculture Centres in Asia-Pacific (NACA), the Office International des Épizooties (OIE) and regional and international specialists. One of the goals identified under this strategy is the development of a comprehensive information database on aquatic animal health, the Aquatic Animal Pathogen and Quarantine Information System (AAPQIS; www.enaca.org/aapqis/). Information provided via AAPQIS and through these checklists is intended to assist aquatic animal health workers, quarantine officers and policy makers in developing national strategies to minimize the risks associated with movement of pathogens of aquatic animals, and to make informed assessments on the possible threats presented by proposed movements of individual species of live fish and shellfish between countries. Further information on the regional programme is found in the "Asia Regional Technical Guidelines on Health Management of Live Aquatic Animals and t he Beijing Consensus and Implementation Strategy" (FAO Fisheries Technical Paper No. 402). -
Book (series)DNA-based molecular diagnostic techniques: research needs for standardization and validation of the detection of aquatic animal pathogens and diseases.
Report and proceedings of the Expert Workshop on DNA-based Molecular Diagnostic Techniques: Research Needs for Standardization and Validation of the Detection of Aquatic Animal Pathogens and Diseases. Bangkok, Thailand, 7-9 February 1999.

These technologies offer rapid results with potentially high sensitivity and specificity, at relatively low cost. Recognition of these advantages has led to rapid adoption of available DNA-based tests, particularly in shrimp culture for which histological procedures lack specificity and culture-based methods have not been possible. However, few if any of the available tests have been assessed appropriately against other diagnostic methods or standardized and validated for specified applications. In fish and shrimp, type or strain specificity of most tests for pathogens in the Asian region is poorly understood and, in molluscs, there is little information on the significant pathogens and few tests of any kind have been developed. Furthermore, tests presently avai lable are frequently conducted by technicians who may not be sufficiently aware of the need for stringent test protocols or the meaning and limitations of the data generated. Implementation of standardized practices that produce reliable, useful and comparable data will require a significant investment in research, training and infrastructure development. Effective implementation will also be assisted by enhanced communication between aquatic animal health practitioners in the region and scienti sts with expertise in molecular diagnostic technologies. This review recommends development by FAO/NACA of 2 programs of managed cooperative research to assist more effective use of DNA-based detection tests. Program A should focus on improving the knowledge base by identification of new and emerging pathogens, relating pathogens in the region to those described elsewhere, and defining the extent of genetic variation between related pathogens in the region. Program B should draw on information currently available or obtained from Program A to develop suitably specific DNA-based diagnostic methods and to evaluate and validate the methods for disease diagnosis and pathogen screening programs. To increase the availability of scientists and technicians with skills in pathology and molecular diagnostic technologies, the review also recommends development of FAO/NACA-sponsored training programs for staff from key laboratories in the region. Training priorities should be in: i) the use of standard histopathological methods for health screening of fish and molluscs; and ii) the use of standard DNA-based methods for pathogen detection including sample collection, application of test protocols and the analysis and interpretation of test results. Because of the urgency of disease problems and the availability of suitable tests, training in DNA-based methods should focus initially on detection of shrimp pathogens. The review also recommends the development of a laboratory accredita tion program in order to achieve standardization of sampling methods and test procedures. The establishment of reference laboratories will assist accreditation for each of the major pathogens. Laboratory accreditation and training programs should complement the activities of OIE in obtaining internationally agreed test standards for molecular diagnostic technologies. -
Book (series)Improving biosecurity through prudent and responsible use of veterinary medicines in aquatic food production 2012
Also available in:
No results found.The current trend towards increasing intensification and diversification of global aquaculture has lead to its dramatic growth, thus making aquaculture an important food-producing sector that provides an essential source of aquatic protein for a growing human population. For both developed and developing countries, the sector is recognized as creator of jobs and an important source of foreign export earnings. The expansion of commercial aquaculture, as is the case in commercial livestock and pou ltry production, has necessitated the routine use of veterinary medicines to prevent and treat disease outbreaks due to pathogens, assure healthy stocks and maximize production. The expanded and occasionally irresponsible global movements of live aquatic animals have been accompanied by the transboundary spread of a wide variety of pathogens that have sometimes caused serious damage to aquatic food productivity and resulted in serious pathogens becoming endemic in culture systems and the natura l aquatic environment. The use of appropriate antimicrobial treatments is one of the most effective management responses to emergencies associated with infectious disease epizootics. However, their inappropriate use can lead to problems related to increased frequency of bacterial resistance and the potential transfer of resistance genes in bacteria from the aquatic environment to other bacteria. Injudicious use of antimicrobials has also resulted in the occurrence of their residues in aquacultur e products, and as a consequence, bans by importing countries and associated economic impacts, including market loss have occurred. Since disease emergencies can happen even in well-managed aquaculture operations, careful planning on the use antimicrobials is essential in order to maximize their efficacy and minimize the selection pressure for increased frequencies of resistant variants. The prudent and responsible use of veterinary medicines is an essential component of successful commercial aq uaculture production systems. The FAO/AAHRI Expert Workshop on Improving Biosecurity through Prudent and Responsible Use of Veterinary Medicines in Aquatic Food Production was convened in Bangkok, Thailand from 15 to 18 December 2009, in order to understand the current status of the use of antimicrobials in aquaculture and to discuss the concerns and impacts of their irresponsible use on human health, the aquatic environment and trade. Such discussions became the basis for drafting recommenda tions targeted to the state and private sectors and for developing guiding principles on the responsible use of antimicrobials in aquaculture that will be part of the FAO Code of Conduct for Responsible Fisheries Technical Guidelines on Prudent and Responsible Use of Veterinary Medicines in Aquaculture. Since aquaculture is expected to continue to increase its contribution to the world¿s production of aquatic food, offer opportunities to alleviate poverty, increase employment and community de velopment and reduce overexploitation of natural aquatic resources, appropriate guidance to aquaculture stakeholders on the responsible use of veterinary medicines has become essential. Safe and effective veterinary medicines need to be available for efficient aquaculture production, and their use should be in line with established principles on prudent use to safeguard public and animal health. The use of such medicines should be part of national and on-farm biosecurity plans and in accordance with an overall national policy for sustainable aquaculture. This publication is presented in two parts: Part 1 contains 15 technical background papers presented during the expert workshop, contributed by 28 specialists and which served as a basis for the expert workshop deliberations; Part 2 contains the highlights of the expert workshop.
