Ideal growing areas for oysters were identified, where relaying sites were established, which could be able to reduce E. coli counts from 24,000 MPN/ 100 g to ā¤ 20 MPN/ 100 g after 2 weeks of relaying, making the raw oyster safe for human consumption. Comprehensive data on the sanitary quality of the oyster growing …

Studies on genetic structure of populations and its morphological association are important to advance oyster farming. This study was focused to look at the genetic structure of Crassostrea iredalei populations in the Philippines using microsatellite markers through optimization of the identified five loci. This project was conducted in 5 Provinces, Iloilo, Aklan, Capiz, Negros Occidental …
The manual āHatchery Production of Single Spats Slipper-shaped Oyster Crassostrea iredaleiā is one of the major outputs of the National Oyster R&D Program under the projects, “Broodstock Management and Conditioning for the Oyster, Crassostrea iredalei to Maximize Production” and “Refinement of the Larval, Post Larval, and Nursery Rearing Techniques for Crassostrea iredalei,” funded by the …

The Coastal Acidification Program generated information on coastal acidification as a contribution to justify the inclusion of coastal acidification to the National Climate Change Action Plan and to provide actual Philippine coastal acidification data to the Global Ocean Acidification ā Observing Network (GOA-ON). Through this program, data from 63 sites across the country was generated …

This project studied the genetic structure and connectivity of natural populations of representative coral species with varying dispersal potentials based on life history traits, e.g., a broadcast spawner (Acropora digitifera) which likely disperses further distances compared to a brooder which has restricted larval dispersal (Heliopora coerulea), and a species with mixed modes of reproduction and …
Genetic mechanisms that confer stress susceptibility or resilience to corals was determined using RNA-sequencing (RNA-seq) technology. It was discovered that differences in the thermal tolerance of corals correlate with differences in the way that these species deploy their stress response tool kit when subjected to elevated temperature. This project is the first to capture the …
The physiological limits of 17 selected coral species in response to ocean acidification, ocean warming, and anthropogenic nutrient-coastal acidification stress were evaluated using manipulative experiments. As a result, a ranked list of coral stress tolerances was generated showing that corals exhibited lower tolerance to thermal stress than ocean acidification. Moreover, corals exhibit greater declines in …
The reproductive patterns of 18 coral species in Luzon, 13 coral species in Visayas and 11 coral species in Mindanao were assessed while the monthly record of reproductive status of 11 broadcast spawning coral species (i.e., Favites abdita, F. colemani, Acropora hyacinthus, A. valida, A. millepora, A. gemmifera, A. humilis, A. digitifera, A. latistella, A. …
DOST-PCAARRD supported the nationwide coral reef assessment in 2015, which assessed a total of 206 stations using HCC and allowed the development of (1) standardized protocol for reef monitoring, assessment and taxonomic identification, and (2) new scale for classifying the status of coral reefs developed using HCC and national and regional benchmarks, assessment scales and …
This project will investigate the potential role of Type VI Secretion System encoded by Vibrio-causing AHPND during shrimp infection. It has been shown that AHPND is caused by plasmid-encoded binary toxins V. parahaemolyticus Photorhabdus insect-related toxins (PirAVP and PirBVP). However, little is known about the pathogenicity and it remains unknown whether other virulent factors are …
