    Health management of milkfish Chanos chanos 

    ER Cruz-Lacierda, EG Estante, EGT de Jesus-Ayson & VL Corre Jr. - 2015 - Aquaculture Department, Southeast Asian Fisheries Development Center
    This monograph provides updated information on diseases of marine and brackishwater cultured milkfish in the Philippines. The information presented here is largely based on the results of a three-year research project on milkfish at the University of the Philippines Visayas funded by the Department of Science and Technology (DOST). The project involved surveillance and monitoring of hatchery, nursery and grow-out operations for occurrence of diseases as well as on disease diagnosis, prevention and control. Previously documented reports in the Philippines and in other documents, both published and unpublished, are also included in this monograph. The diseases are discussed on a culture phase basis, that is, disease problems encountered in hatchery-reared larvae and fry are listed first, followed by diseases observed in fingerlings and juveniles grown in nursery and grow-out culture areas, and adult stages maintained in broodstock facilities. Information regarding the causative agent, diagnostic procedures, and methods of prevention and control for each disease are provided, if available.

    BO Acosta, RM Coloso, EGT de Jesus-Ayson & JD Toledo (Eds.) - 2011 - Aquaculture Department, Southeast Asian Fisheries Development Center
    This publication represents the proceedings of the Regional Technical Consultation (RTC) on Aquaculture held in Bangkok, Thailand last 17-19 March 2010. The RTC was convened by the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD) as part of the preparatory undertakings for the ASEAN-SEAFDEC Conference on Fisheries held in June 2011. The main objectives of the RTC were to follow-up the developments of aquaculture in Southeast Asia after the 2001 ASEAN-SEAFDEC Millennium Conference on Fisheries and to define the strategic actions for the region s sustainable aquaculture development in the next decade. These proceedings contain 10 country papers and a summary status of implementation of the Resolution and Plan of Actions on six themes (supply of good quality seeds, environment-friendly aquaculture, getting out of the fish meal trap, healthy and wholesome aquaculture, biotechnology and rural aquaculture) which are the outcomes of the 2001 ASEAN-SEAFDEC Millennium Conference on Fisheries. It also presents the thematic papers and a synopsis of discussions on issues and recommendations on four thematic areas: (i) meeting social and economic challenges in aquaculture; (ii) quality seed production for sustainable aquaculture; (iii) healthy and wholesome aquaculture; and (iv) protecting the environment and adapting to climate change. These recommendations are expected to provide baseline information and directions in formulating the Resolution and Plan of Action (aquaculture component) for food security in Southeast Asia towards 2020.

    Viral diseases 

    GD Lio-Po - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Outbreaks of viral infections can cause massive mortalities among cultured fishes or shrimps. Water temperature and age of the fish or shrimps are significant factors that influence the development of viral infections. Most fish viral infections occur at low water temperatures, hence, very few viral infections among fishes in warm water culture systems are reported. In addition, most viral infections occur among fry or fingerlings often causing severe mortalities, while older fish or shrimp develop resistance or are hardly affected. Stress from handling, poor water quality, high stocking density and poor nutrition also affect the severity of viral infections. Finally, aquaculturists should beware in importing non-indigenous fish or shrimps into the country as these are potential carriers of viral pathogens.

    Physical, environmental, and chemical methods of disease prevention and control 

    ER Cruz-Lacierda & GE Erazo-Pagador - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Disease prevention is a primary and cost-effective method in fish health management. It is more effective and economical than attempting to stop a disease that has already set in. Preventive measures have always big advantage over curative practices. Moreover, the drug may not provide remedies under all circumstances. Also, the drug may not help the host survive the infection until the environment is improved. Ideally, fish culturists should strive to decrease the stress-causing factors and eliminate and prevent the entry of pathogenic organisms by strictly adhering to the fish health monitoring programme.

    Serological and DNA-based techniques in disease diagnosis 

    LD de la Peña - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    The improvement of existing serological techniques, development of monoclonal antibody technology and the development of new serological approaches are all working together to provide new tools for the detection of disease-causing organisms in fish and crustaceans. Following the introduction of nucleic acid hybridization technique and PCR, it was recognized that the methods offered a sensitive approach to the detection and identification of specific microorganisms as in the case of a bacterial or viral infection in a variety of sample types. Potentially, a characteristic DNA sequence from a single virus particle or cell of a particular organism can be amplified to detectable levels within a short period of time. Conventional diagnostic methods that involve the culture of microorganisms can take days or weeks to complete or very tedious to perform. PCR offers a rapid, very sensitive, very specific and simple alternative. Further developments in immunodiagnostics and emerging technologies such as quantitative PCR, lateral flow assay and loop-mediated isothermal amplification diagnostic tests will revolutionize the detection, identification and quantification of the infectious disease agents. Further, advancements in gene sequencing analyses will enable strain differentiation among closely related viruses.

    Nutritional diseases 

    CR Lavilla-Pitogo & EC Amar - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Diagnosis of nutritional diseases is difficult because many signs exhibited by fish are non-specific and most nutritional deficiencies are hard to define. A compilation of data on feed composition and feeding management, as well as husbandry practices, are needed to define a case. Most of data on fish and shrimp nutritional diseases were gathered under experimental conditions. Under farm conditions, most of that definition would be clouded with errors in husbandry practices or secondary infection. Therefore, attempts to diagnose nutritional diseases should be carefully done using every available technique to define the case.

    Environmental and other non-infectious diseases 

    GE Erazo-Pagador & RV Pakingking Jr. - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    The chapter presents some of the environmental non-infectious diseases of aquatic animals. Non-infectious diseases are caused by adverse environmental conditions, nutritional disorders, or genetic defects. While they can result a sudden mass mortality or death, they are not contagious. Environmental diseases are the most important in aquaculture. This includes low dissolved oxygen, high ammonia, high nitrite, or natural or man-made toxins in the aquatic environment.

    Histology as a tool in disease diagnosis 

    ES Catap & ER Cruz-Lacierda - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Histology is an important tool in fish disease diagnosis as it affords the comparison of normal structures or morphology of tissues against those from diseased fish. However, correct diagnosis and confirmation of changes associated with diseases require proper specimen processing and some degree of expertise in histopathology.

    The four basic types of tissues are: epithelial, connective, muscular and nervous. An organ is usually a combination of these four tissue types. It is important to remember that the histology or structure of an organ is always related to the function it performs.

    Disease development 

    CR Lavilla-Pitogo - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Disease occurrence is one of the biggest deterrents to sustainable production in aquaculture. It is therefore important to enhance awareness among various sectors of the importance of health management in the aquaculture industry. This can be done through education and information dissemination. Students in fisheries and veterinary medicine need to have adequate background information on the aquatic animal disease and health management to understand the problems and needs of a fast-growing aquaculture industry. Recognizing disease signs early and using mortality pattern as a clue to the disease agent involved will not only make diagnosis easier, but it will also prevent massive losses by timely implementation of remedial measures.

    Bacterial diseases 

    EV Alapide-Tendencia & LD de la Peña - In GD Lio-Po & Y Inui (Eds.), Health Management in Aquaculture, 2010 - Aquaculture Department, Southeast Asian Fisheries Development Center
    Fish and crustaceans that are not weakened by poor environmental conditions, or by other causes, such as parasitic infestation, nutritional deficiency, handling stress, or chemical intoxication, are more resistant to bacterial infections. This is due to the presence of a large amount of bactericidal substances in the blood, which helps overcome infections. So, the best precaution against the occurrence of bacterial infections is to provide the fish with optimum environmental conditions, adequate amounts of the right kinds of food and avoidance of stress, including overcrowding. Vaccination/ immunization and genetic manipulation (i.e., the development of specific pathogen resistant fry) are also some ways of preventing bacterial diseases. The use of antibiotics should always be an option of the last resort.
