Project to determine profile of shrimp exposed to fluctuating temperatures kicks off

A newly-approved project titled, “Transcriptome and Gut Metagenome Profile of Penaeus vannamei Exposed to Fluctuating Environmental Temperatures” recently kicked off.

The project aims to determine the muscle, haemolymph and hepatopancreas transcriptome profile of P. vannamei exposed to fluctuating temperatures; elucidate the influence of fluctuating temperatures on the microbiome metagenomic profile of P. vannamei; and to develop a strategy to prevent microbial infection and stunted growth of cultured P. vannamei due to temperature stress.


Led by Angel Queenee Dequito, the project’s inception meeting was held at the University of the Philippines Visayas, Iloilo City on August 28, 2019. The meeting was led by the Inland Aquatic Resources Research Division (IARRD) of the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD).

This project is one of the anchor projects of the Philippine Genome Center (PGC) Visayas and is being funded by DOST.

Dr. Adelaida T. Calpe, Senior Science Research Specialist and Head of the Monitoring and Evaluation Unit of IARRD-PCAARRD presented the DOST Guidelines and the rules and regulations in the implementation of Grants-in-Aid (GIA)-funded projects and discussed the roles of researchers, implementing agency, collaborating agencies, and PCAARRD in the implementation of the project. They also finalized the project’s methodology, work plan, and changes in the approved project.

The project is envisioned to come up with a practical approach to prevent stunted growth and microbial infection in farmed shrimp in the country.
