Southeast Asian Fisheries Development Center – Aquaculture Department SEAFDEC -AQD
The Tigbauan Main Station (TMS) is the AQD headquarters situated right on the beach on the south coast of Panay Island, where brackishwater pond aquaculture has historically been a big industry. The 40-hectare complex includes various research laboratories, hatcheries, and broodstock tanks for experiments in artificial propagation, feed development, and health management.

Fish Health Section
• Bacteriology 2 Scientists with PhD • Virology 1 Scientist with PhD • Parasitology 1 Scientist with M Sc • Immunology 2 Scientists with PhD
1 Senior Technical Assistant (BSc) – Bacteriology 2 Senior Technical Assistants (BSc) –Bacteriology, Virology 1 Technical Assistant (BSc) – Parasitology and Histopathology 1 Research Technician (BSc) – Bacteriology and Virology
The Fish Health Section is staffed according to positions approved by the
SEAFDEC Program Committee as follows:
In addition, there are 4 Technical Assistants hired on fixed-term basis under projects funded externally by the Government of Japan Trust Fund (GOJ-TF) and the Japan international Research Center for Agricultural Sciences (JIRCAS).
All scientists in the section are active researchers with
at least two approved studies per year. One scientist is designated as the Section Head, one serves as Program Leader of the Research Division’s thematic area with fish health component, and another scientist is designated in-charge of the Diagnostic Services. All scientists contribute their expertise and are consulted in resolving disease cases.
The following are some research studies conducted by Fish Health Section researchers. Carriers for practical delivery of vaccines to shrimp and other crustaceans are being evaluated. This study compares the efficacy of protein (WSSV) vaccines delivered via microparticles made from chitosan and alginate.
Ongoing Research at the Fish Health Section
Also, the host response of Lates calcarifer to Amyloodinium ocellatum is being examined. The interaction between a fish host and a protozoan parasite may give some guide as to how outbreaks in hatcheries due to parasitic infestations might be prevented or controlled.
In order to establish a management technology for disease tolerant and sustainable aquaculture environment, research employing epidemiological approaches is continuing.
Research on parasitic and shell diseases of abalone (Haliotis asinina) in the Philippines aims to establish baseline information on parasitic diseases of this species in the country.
In addition, the molecular diagnosis and prevention of economically important viruses in fish and shrimp is developing sensitive but economical molecular methods of pathogen detection, including means to prevent occurrence of some target viruses.
There is also screening for antimicrobial activities of crude extracts from Philippine red seaweeds which attempts to find natural substitutes to antimicrobial drugs from farmed marine organisms.
Finally, immunization regimen for the prevention of viral nervous necrosis (VNN) in high value marine broodfish is being developed. Once established, vaccination could be an efficacious way of preventing VNN infection in marine fish.

Facilities
The SEAFDEC AQD Fish Health Laboratory is committed to comply with OIE aquatic animal health standards. The laboratory has participated and passed the ring test for diagnosis of shrimp pathogens conducted by the OIE Reference Laboratory at the University of Arizona. It is also a participant in the ongoing Asia Regional Diagnostic Laboratory Proficiency Testing being facilitated by the Network of Aquaculture Centers in Asia and the Pacific (NACA).
Quality Control
FHS Diagnostic Services Laboratory has capability for PCR analyses of the following viruses: • Infectious Myonecrosis Virus (IMNV) • Infectious Hypodermal and Haematopoietic Necrosis
