Book Description
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.

Book Description
The PMP/AB refers to a pathway aimed at enhancing aquaculture biosecurity by building on existing frameworks, capacity and appropriate tools using risk-based approaches and public-private sector partnerships. It is expected to result in sustainable (i) reduction in burden of diseases; (ii) improvement of aquatic health and welfare at farm, national and regional levels; (iii) minimization of global spread of diseases; (iv) optimization of socio-economic benefits from aquaculture; (v) attraction of investment opportunities into aquaculture; and (vi) achievement of One Health goals. In the context of the PMP/AB, biosecurity refers to the cost-effective management of risks posed by pathogens to aquaculture through a strategic approach at the enterprise, local-sector, national and international levels with shared public-private responsibilities. This guidance document for PMP/AB application contains the rationale, vision, mission, scope, goals and benefits of the PMP/AB. The four stages of the PMP/AB are described in detail, including the overall objectives and key outcomes to complete each stage. It also presents a general stepwise process and recommended activities for completing the different stages. The PMP/AB checklist is divided into four broad categories, namely: Sectors and Stakeholders; Aquatic Health Services; Surveillance, Monitoring and Diagnostics; and Management and Evaluation.

Book Description
Aquaculture Pathophysiology, Volume II. Crustacean and Molluscan Diseases is a concise, practical reference on shellfish diseases of significant risk to aquaculture. Its value to the veterinarian, fish health biologist or extensionist, fish pathologist and fish health diagnostician is its easy reach for critical information on the diagnosis and management of significant infectious and non-infectious diseases for the major temperate, subtropical and tropical shellfish species of commercial and fisheries importance. This volume should be read in partnership with volume one on finfish diseases as the principles and approach to the diagnosis and management of aquacultured animal species are similar. This comprehensive resource is ideal for researchers, teachers, students, diagnostic laboratory scientists, aquaculture technicians, and farmers who need to be competent across both finfish and shellfish health issues. - Presents a focus on the disease process of major or emerging viral, bacterial, fungal and parasitic infections affecting aquacultured shellfish species e.g., shrimp, lobsters, crayfish, crabs, oysters, mussels, abalone and scallops - Focuses on important or emerging environmental, nutritional, genetic, deformity, toxicological, endocrine disruption, and neoplastic diseases in crustaceans and mollusks - Provides a review of the immunology of shellfish relevant to a practical understanding of disease diagnosis and management - Includes an overview of laboratory diagnostic methods relevant to the detection of shellfish diseases - Discusses the diverse risk factors of shellfish diseases and options for their control

Book Description
Pathology and Epidemiology of Aquatic Animal Diseases for Practitioners Comprehensive reference on the diseases and applied epidemiology of all aquatic animal taxa, including invertebrates and vertebrates Pathology and Epidemiology of Aquatic Animal Diseases for Practitioners provides information on the diseases and applied epidemiology of all aquatic animal taxa, including invertebrates and vertebrates, along with information on applied epidemiology, acknowledging the One Health concept, and discussion on probabilities of disease outbreaks occurring and assesses the economic costs of treating those outbreaks, if applicable. Divided into two sections, the book looks at the pathology of major aquatic taxa and their associated infectious diseases—parasitic, viral, and bacterial—and non-infectious diseases. Each includes an overview, their host range and transmission, signs and diagnosis, differentials, and treatment and management. These assets are accompanied by clinical signs-lesion differential charts. Sample topics discussed in Pathology and Epidemiology of Aquatic Animal Diseases include: Echinoderms, including crinoidea (crinoids, sea lilies, feather stars, and asteroidea), sea stars/starfish, and ophiuroidea (brittle stars and basket stars) Reptiles, including turtles (freshwater and marine), crocodilians, marine iguanas, and sea snakes Pinnipeds, including otariidae (eared seals), odobenidae (walruses), phocidae (earless seals), mustelidae (otters), and sirenia (manatees and dugongs) Tropical marine aquarium fish (damselfish, angelfish, gobies, wrasses, parrotfish, butterfly fish, and clownfish) and anemones. A highly useful reference for veterinary practitioners, academic staff, and researchers, Pathology and Epidemiology of Aquatic Animal Diseases is also suitable for those who are interested in aquatic veterinary medicine and serves as a companion to Fundamentals of Aquatic Veterinary Medicine, written by the same editorial team.

Book Description
This report documents the accomplishments of the FAO Project TCP/MIC/3603/C2 – “National Aquatic Animal Health and Biosecurity Strategy” that was implemented in 2019 for the Federated States of Micronesia (FSM). These include the following: (i) Round-table discussions on aquaculture development, biosecurity legislation, aquatic animal health and aquaculture biosecurity (21–22 May 2019); (ii) Technical Seminar on Basic Aquatic Animal Health and Aquaculture Biosecurity (23 May 2019); (iii) National Consultation on Aquaculture Development, Biosecurity Legislation, Aquatic Animal Health (24 May 2019); and (iv) Introductory training course on risk analysis within the Progressive Management Pathway for Improving Aquaculture Biosecurity (PMP/AB) (27–28 May 2019). The various activities undertaken during the field mission provided the basis for drafting the National Strategy on Aquatic Animal Health (NSAAH) and the National Aquatic Pathogen List (NAPL) for FSM. There is a need to conduct another round of national consultations in order to generate feedback prior to finalizing the documents and approval. The next step will be to incorporate them into the government’s policy documents and work with partners for joint resource mobilization to support implementation. The report also contains a list of recommendations that the Government of FSM should consider to improve capacities in aquatic animal health and aquaculture biosecurity.
