This book was released on 2020-11-24 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of this Shrimp acute hepatopancreatic necrosis disease strategy manual provides information and guidance relevant to the development of policies to respond to outbreaks of acute hepatopancreatic necrosis disease (AHPND) in farmed marine shrimp. The etiologic agents for AHPND are virulent strains of bacteria belonging to the genus Vibrio parahaemolyticus and related species, which harbor specific toxin genes. While these bacterial species are part of the normal microflora of the marine environment, they may cause substantial mortalities in whiteleg shrimp (Penaeus vannamei) and giant tiger prawn (Penaeus monodon) cultured in countries in Asia and the Americas. These strains of these Vibrio bacteria secrete a PirABvp binary toxin resulting in sloughing of tubule epithelial cells and dysfunctions of the hepatopancreas in the acute form; mortality can reach 100 percent in affected ponds. Chronic presentation of this disease involves secondary bacterial infection of hepatopancreas and running mortality over the culture cycle. Acute or chronic presentation would greatly depend on the culture conditions. This disease can be considered a toxicosis rather than an infection. Economic losses due to this disease have amounted to over USD 7 billion annually. Further outbreaks of AHPND, particularly in areas that are currently free of the disease, would be expected to experience similar devastating effects on local shrimp producers and the surrounding communities; and thus, there is an urgent need to develop a contingency plan to control and eradicate this disease. This manual includes information on: 1) the nature of AHPND: a brief review of current knowledge in disease etiology, susceptible species and global distribution; 2) diagnosis of disease: a description of gross clinical signs and laboratory methods; 3) prevention and treatment: farm management, the use and development of antibiotics, bacteriophages, probiotics, disease-tolerant shrimp, shrimp immunity and vaccination; 4) epidemiology: AHPND’s geographic distribution, genotype, persistence in the environment, reservoir hosts, modes of transmission, risk factors, and economic impacts; 5) principles of control and eradication: methods for containment, mitigation and eradication of AHPND, and trade and industry considerations; and 6) policy development and implementation: AHPND-specific objectives, options and strategies for eradication and control, education, capacity building, funding, and compensation.

Download or read book Determination Characterization and Control Measures of the Agent Causing Early Mortality Syndrome EMS Also Known as Acute Hepatopancreatic Necrosis Syndrome AHPNS in Farmed Penaeid Shrimp written by Loc Huu Tran and published by . This book was released on 2013 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of studies were conducted on an emerging disease in farmed penaeid shrimp. This disease was first named as Early Mortality Syndrome (EMS) or more descriptively as Acute Hepatopancreatic Necrosis Syndrome (AHPNS). As part of the outcome of this research, the etiology of EMS/AHPNS was demonstrated. EMS was first classified as an idiopathic disease because no causative agent had been identified. Preliminary studies conducted in Vietnam in 2012 by the University of Arizona Aquaculture Pathology Laboratory (UAZ-APL) indicated that EMS is infectious (Tran et al., 2013). The agent was identified as a unique strain of Vibrio parahaemolyticus. Hence, EMS has a bacterial etiology confirmed by satisfying Koch's Postulates. Further studies focusing on the bacterial isolate causing EMS revealed that the agent could produce toxin(s), which is responsible for the primary pathology in affected shrimp. Since the causative agent has been identified, we propose a new name for EMS as Acute Hepatopancreatic Necrosis Disease (AHPND). Characterizations of the AHPND-causing Vibrio parahaemolyticus: Biochemical methods and molecular methods were used. Based on these results, various diagnostic methods were developed including polymerase chain reaction (PCR) test and biochemical tests. Other aspects of the AHPND causing V. parahaemolyticus were also run to determine such as antibiogram and the development of resistance mechanism of the bacteria exposed to farm conditions with antibiotic medications, pathogenicity, and infection dose of the bacteria, mode of infection, mechanisms governing the toxin production, and effects of environmental parameters on the invasion of the agent. Some proposed control measures for AHPND: Several antibiotic-free approaches were tested to determine viable control methods for AHPND. The principle proposed control method is to increase biosecurity. With the PCR method that has been developed, potential sources of the pathogen such as post-larvae and broodstock can be tested. As more and more insights of the pathogen were explored, the behavior of the pathogen was further elucidated. Based on this, control methods such as using polyculture with tilapia, probiotics, and bioflocs system were also tested. Several improvements in shrimp farming practices that may reduce the outbreak of the disease were also proposed.

This book was released on 2018-11-19 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecosystem approach to aquaculture provides the conceptual guideline to spatial planning and management. This publication describes the three major steps in spatial planning and management, namely, zoning, site selection and design of an aquaculture management area, or AMA. The rationale for and objectives of each step, the ways (methodologies) to implement it, and the means (tools) that are available to enable a methodology are described in a stepwise fashion. Recommendations to practitioner s and policy-makers are provided. A separate policy brief accompanies this paper. The benefits from spatial planning and management are numerous and include higher productivity and returns for investors, and more effective mitigation of environmental, economic and social risks, the details of which are provided in this paper. This publication is organized in two parts. Part one is the “Guidance”; it is the main body of the document and describes the processes and steps for spatial planning, incl uding aquaculture zoning, site selection and area management. Part two of the publication includes six annexes that present key topics, including: (i) binding and non-legally binding international instruments, which set the context for sustainable national aquaculture; (ii) biosecurity zoning; (iii) aquaculture certification and zonal management; (iv) an overview of key tools and models that can be used to facilitate and inform the spatial planning process; (v) case studies from ten countries – Brazil, Chile, China, Indonesia, Mexico, Oman, the Philippines, Turkey, Uganda and the United Kingdom of Great Britain and Northern Ireland; and (vi) a workshop report. The country case studies illustrate key aspects of the implementation of spatial planning and management at the national level, but mostly within local contexts.

This book was released on 2019-07-24 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.
