July 15, 2022 Dear Recaredo IV Sarmiento, Greetings! Thank you for your request dated Jul 04, 2022 01:17:53 PM under Executive Order No. 2 (s. 2016) on Freedom of Information in the Executive Branch. Your Request You asked for Feasibility of Recirculating Aquaculture System for Lapulapu and Prawn, Designs. Response to Request This is to formally acknowledge your request for information from the Bureau of Fisheries and Aquatic Resources. With regards to your request, kindly refer to the response of the concerned division: As per inquiry with BFAR Munoz, RFO III & 4A, the BFAR has no feasibility study conducted for RAS on Lapu-Lapu and prawn. However, we did some research and SEAFDEC has made several studies on RAS (see attached documents). The "Feasibility Study of A Recirculation Aquaculture System conducted by Padak Anak Bijo for Arctic charr (Salvelinus alpinus) and seabass (Lates calcarifer) in Malaysia is also similar for Grouper culture since they are marine species and carnivorous. You may use their document/study as reference. The other RAS reference (from other countries) shows the similarity of set-ups and general processes and water flows for RAS which includes: fish culture tanks, mechanical filtration, biofiltration, degasser, reservoir tank, pump, disinfectant unit, biofilter, Oxygenation unit and waste water. BFAR RFO IV-A currently implements RAS for Tilapia Hatchery while BFAR RFO 3 has no RAS as per inquiry. In addition, you may get in touch with state universities that have a study on RAS such as Central Luzon State University and Don Mariano Marcos State University. Thank you! Your right to request a review If you are not satisfied with the result of the review, you then have the right to appeal to the Office of the President under Administrative Order No. 22 (s. 2011). Thank you. Respectfully, FOI Decision Maker FOI Receiving Officer
