Representing the Philippines, Dr. Mary Nia Santos, Scientist I and chief of the Aquatic Animal Health Section of the DA-National Fisheries Research and Development Institute (NFRDI), presented her research at “Aquaculture America 2026,” organized by the World Aquaculture Society on February 17-19, 2026 in Las Vegas, USA.

In the Aquatic Animal Health session, Dr. Santos shared her research on Acute Hepatopancreatic Necrosis Disease (AHPND), a serious bacterial infection that affects shrimp and can cause significant losses in aquaculture. She explained how certain Vibrio bacteria use specific genetic tools, known as the Type VI Secretion System, to deliver toxins, including the pirAB genes, which make the bacteria more harmful to shrimp. By studying these mechanisms at the genomic level, her work helps scientists understand why the disease spreads and how it damages shrimp. Her presentation was well-received by international experts, earning positive feedback and an invitation to submit her research to the Journal of Aquatic Animal Health.

Dr. Mary Jane Amar, collaborator in the NFRDI-funded project on Black Soldier Fly (BSF) larvae as an alternative protein source for tilapia, also presented findings under the Alternative Feeds session.

The conference fostered scientific exchange on aquatic animal health, alternative feeds, microbiome research, and sustainable aquaculture systems. Dr. Santos explored potential collaborations on shrimp health management, larval resilience, and innovative feed ingredients.

Participation in this global event underscores NFRDI’s commitment to advancing science-based solutions and strengthening international partnerships for sustainable aquaculture in the Philippines.

Dr. Santos’s attendance was funded by the NAST Scientific Career System. ### (Rosalie G. Prieto)
