Dr. Edgar C. Amar of SEAFDEC/AQD talked on the Novel Strategies to reduce disease incidence in mud crab hatchery and grow out; and Dr. Eleanor A. Tendencia, SEAFDEC/AQD presented the Surveillance of emerging diseases in wild and farmed mud crabs: Application of conventional and molecular approaches for the Disease Management for Improved Mud Crab Production,

Maningas of UST; and 3) Biocontrol against early mortality syndrome/Acute Hepatopancreatic Necrosis Disease causing bacteria using tilapia, greenwater, immunostimulants and biofioc - Dr. Rex Ferdinand Traifalgar of UPV.
For the “Tiger Shrimp (Paneaeus monodon) Genomics Program,” Dr. Arturo Liuisima of UPMSI presented the Application of genomics in the development of genome wide markers linked to production traits in Panaeus monodon and Genomic markers for assessment of inbreeding and morphophenotype-genotype association mapping in Penaeus monodon.
The following were presented under “Development of Diagnostic Tools Through Genomics and Establishment of the Philippine Shrimp Pathogen Bio-bank and on-line Biosurveillance and Information Resource” cluster: Shrimp pathogenous towards a competitive and sustainable Philippine shrimp industry - Dr. Cynthia P. Saloma, UPD; Establishment of Philippine shrimp pathogen nio-bank and on-line biosurveillance information resource- Dr. Edgar C. Amar, SEAFDEC/AQD; and Development of shrimp pathogen diagnostic tools using nested PCR and lateral flow strip biosensors with mobile app and cloud-based information management - Dr. Nina Rosario L. Rojas, AdMU.
Two papers were presented in “Integrated & Sustainable Development Program for the Shrimp Industry” cluster and these are: Reducing losses in the shrimp industry using developed technologies- Prof. Valeriano L. Corre, Jr. of UPV; and Technology transfer and adoption of developed LAMP-WSSV assay to shrimp farmers- Dr. Mary Beth B. Maningas of UST.
Maningas also presented Mas production of dsRNA to mitigate WSSV infection in shrimp for the “Tiger Shrimp (Penaeus monodon) Genomics Program.”
Corre discussed Field trial of Protein Enriched Copra Meal (PECM) as feed protein for tilapia, milkfish and shrimp under the “Aquafeed R&D Program.”
The Mussel R&D Programs yielded papers for the “Enhancement of Hatchery Nursery Practices for a Reliable Supply of Quality Seeds for the Green-lipped Mussel (Perna viridis) Farming,” which include: Refinement of broodstock maintenance , larval and spat rearing technologies for sustained seed production of the green mussel (Perna viridis) - Dr. Liberato V. Laureta, UPV; Development of remote setting and nursery technologies for the green mussel (Perna viridis) - Dr. Carlos Baylon of UPV; and Genetic characterization and selective breeding of green mussel (Perna viridis) - Dr. Philip Ian P. Padilla, UPV.
For the “Improved Grow-out Technology for a Sustainable Mussel Industry,” the following were presented: 1) Transplantation and spatfall determination of green mussel and another paper Causes and management of mass mortalities in the culture of green mussels – Baylon, UPV; 2) Raft and longline method for grow-out of mussels Baylon, UPV, Prof. Renato Diocton, SSU, and Prof. Diony Cahilig, CapSu; 3) Modeling site selection for expansion in new areas - Dr. Eunice A. Layugan, CSU; and 4) Production of safe mussel using environment-friendly culture methods in sites near urban areas- Ms. Armina B. Pugay, CavSU.
The “Post Harvest Program for a Sustainable High Quality and Safe Mussel Products” also had two presentations: Primary processing techniques for Philippine green mussels - Ms. Loda M. Naconal of UPV; and The Development of depuration and relaying techniques for Philippine green mussel - Ms. Rose T. Mueda, UPV.
A sharing of R&D Programs for different clusters including industry feedbacks was conducted with the Department of Agriculture-Bureau of Agricultural Research (DA-BAR), Bureau of Fisheries and Aquatic Research (BFAR) and the Commission of Higher Education (CHED). Dr. Norida Samson, Dr. Adelaida T. Calpe, and Dr. Lourdes C. Darvin, Asst. Director PCAARR-IARRD served as moderators for the open forums after the different cluster presentations.
