Bamboo raft technology in Pangasinan yields 480kg of oyster

An initial harvest of 480kg of oyster (𝘔𝘢𝘨𝘢𝘭𝘭𝘢𝘯𝘢 𝘴𝘱𝘱.) showed promising results of the bamboo raft technology by utilizing floaters, bamboo, and plastic straps in producing oysters. The harvest activity was conducted on 8 February 2023 at Bolinao, Alaminos City, Pangasinan. 

DA-National Fisheries Research and Development Institute (NFRDI), with funding support from DA-BAR, is currently implementing a project to boost oyster production and fisherfolk’s income in the municipalities of Anda, Bani, Bolinao, Alaminos City, and Sual in Pangasinan. 

Initially developed and verified by the National Fisheries Development Center of the DA-Bureau of Fisheries and Aquatic Resources together with Japan International Cooperation Agency, the technology can reduce mortality rate and enable faster growth of oysters; and produce good quality meat.

“As compared to the traditional stake method of oyster culture, bamboo raft technology is an effective and environment-friendly alternative method in producing oysters,” DA-NFRDI Aquaculture Research and Development Division chief and project leader Dr. Joseph Christopher C. Rayos said.  

Another innovation is the hardening practice that can lead in the control and eradication of fouling organisms resulting in higher or premium quality of oyster yield. By using the technology, oysters can be harvested after a culture period of three to six months.

Dr. Rayos, during a discussion, stressed the potential of the technology in strengthening the value chain of oyster; thus, resulting in a steady production that can address demands of potential institutional buyers and investors. 

During the activity, DA-BAR OIC-assistant director Dr. Anthony B. Obligado underscored the importance of the bureau's continuous support to various research for development projects and initiatives toward addressing challenges in food sufficiency and increasing fisherfolk’s profit.

Meanwhile, DA-NFRDI executive director Dr. Lilian C. Garcia thanked the local government units of Pangasinan and other government agencies for putting up collaborative efforts in the project toward augmenting the income of fisherfolk.

Also present during the activity were DA-BAR Research Coordination Division head Julia A. Lapitan, DA-BFAR-Ilocos Region regional director Rosario Segundina P. Gaerlan, representatives from the local government unit of Bolinao, and fisherfolk associations.
