AQD begins new work program after the conclusion of the ASEAN-SEAFDEC Conference on sustainable fisheries for food security towards 2020 that was held 13-17 June 2011 in Bangkok, Thailand. With partner institutions, AQD will focus on thematic areas, from ensuring quality seed supply to meeting social & economic needs of SEAFDEC member countries.

AQD gets the thumbs up from the Philippine Department of Agriculture and its Bureau of Fisheries and Aquatic Resources (BFAR) for 38 years of developing science-based technologies for the aquaculture sector. BFAR National Director Atty. Asis Perez committed BFAR to utilizing the valuable research done by SEAFDEC Aquaculture Department (AQD). He also expressed his appreciation to AQD for coming up with a low-cost, small-scale, abalone and multi-species marine fish hatchery which, he said, is what our country needs.
As part of AQD’s weeklong anniversary celebration, a technology lecture series (left inset) with invited guests from the private sector and the academe was held on 6 July. Furthermore, three events took place on 7 July. These were (1) auction of artwork done by Filipino schoolchildren to benefit the Malalison community, (2) the Dean Domiciano Villaluz Memorial lecture on Feed formulation for healthy and wholesome aquaculture by AQD Scientist Dr. Relicardo Coloso (middle inset), and (3) the launching of AQD’s new publications including two aquaculture extension manuals, six flyers, one poster, AQD’s annual report, the proceedings of the Regional technical consultation on sustainable aquaculture development for food security in Southeast Asia towards 2020, and AQD institutional repository.
Meanwhile, AQD Scientist Dr. Emilia Quinitio (right inset) was given a Certificate of recognition for bagging this year’s Dr. Elvira O. Tan Memorial award given by the Department of Science and Technology (Philippines) for best published paper in the inland fisheries category for her work, Domestication of the mud crab Scylla serrata.
Good aquaculture practices (GAPs) mean production of safe aquaculture products for human consumption. This is the consensus of 17 experts from SEAFDEC member countries who attended the International seminar on food safety in aquaculture in Southeast Asia on 22 January in Iloilo, Philippines. The seminar was hosted by SEAFDEC Aquaculture Department (AQD) and funded by the Government of Japan Trust Fund (GOJ-TF), and was intended to share new information on food safety in Southeast Asia.
Food safety has become an important issue because most of the food fish that people are eating already comes from aquaculture; according to FAO, 43% of the world’s fish supply in 2008 is from aquaculture. Under fish culture conditions and without GAPs microbiological contaminants, antibiotic residues, chemical contaminants, and parasites can become problems.
GAPs is an integrated approach to fishfarming that includes, among others, appropriate fish health management and effluent management practices that would no longer necessitate the use of antibiotics and other harmful products.
At AQD, studies on food safety are funded by GOJ-TF and AQD, including (1) the determination of withdrawal periods of antibiotics in shrimps, milkfish and other freshwater fish species; (2) the surveillance of chemical contaminants in aquaculture products like feeds as well as chemical residues in aquaculture systems and cultured fish; (3) investigation of the situation of antibiotics/chemicals usage and regulations in aquaculture; and (4) establishment of guidelines on the proper usage of antibiotic and chemicals in aquaculture.
AQD’s laboratory and research facilities are capable of conducting microbiological, chemical, and PCR-based analyses used in monitoring food safety. AQD’s analytical procedures and protocols are verifiable by third-parties; in particular, AQD has passed the Inter-Laboratory Calibration Test (ring test) for the detection of shrimp viruses conducted by the World Organization for Animal Health (OIE) through the University of Arizona (USA).
Governments in Southeast Asia have taken measures to ensure food safety to protect its public. Thailand and the Philippines, for example, are monitoring residues of harmful substances in fish and inspecting aquafarms. Farms that passed the set standards for GAPs are certified as safe sources of food fish.
Participants included representatives from Cambodia (1), Malaysia (1), Myanmar (1), Thailand (2), Singapore (3), and the Philippines (10) and 30 AQD researchers and staff.
The seminar was organized by Dr. RM Coloso (chair), Dr. M Catacutan, Ms. M Arnaiz, Ms. KG Corre (members), and Dr. Azuma (adviser).
AQD completed the five training courses intended to enhance and strengthen the capacity and capability of BFAR’s regional fisheries training centers in aquaculture. The “Training of trainers on hatchery and nursery of selected aquaculture species” was attended by a total of 98 training center staff coming from Aparri, Albay, Samar, Cebu, Palawan, Zamboanga and Davao. The first batch was trained on abalone (29 March to 18 April), the second on seaweeds (26 April to 10 May), the third on sandfish (4 to 17 May), the fourth on marine fish (19 May to 24 June) and the fifth on mud crab (27 June to 19 July).
The courses were held at AQD’s Tigbauan Main Station and Dumangas Brackishwater Station in Iloilo. AQD resource persons lectured on topics such as seed production, nursery & grow-out, and economic evaluation. Moreover, the participants had practical demonstrations on larval rearing as well as microalgae / Artemiaculture and feeding.
BFAR and AQD funded the training of trainers under an agreement signed in early 2011.
To uphold this goal, AQD welcomes research collaboration with academic and R&D institutions, non-government organizations, private sector, and government agencies in SEAFDEC member countries and other parts of the world. Proposals maybe submitted, assessed, and approved at anytime within the year.
Proposals are usually in areas that AQD consider as priorities. However, collaborators may work on their own areas of interest.
At present, the following economically important commodities are under study at AQD:
• mollusks (abalone, top shell, giant clam, oyster-mussel)
• crustaceans (mudcrab, tiger shrimp, white shrimps, giant freshwater prawn)
• fishes (grouper, milkfish, tilapia, bighead carp, catfish, seabass, snapper, siganids)
• seaweeds (Gracilaria, Kappaphycus)
Collaboration may be on the various life stages of the above species (broodstock, hatchery, nursery, grow-out).
If the interest is on biotechnology, AQD has a well-equipped Laboratory for advanced aquaculture technologies and enclosed wet laboratories for the isolated confinement of hormone-treated or genetically manipulated commodities.
Studies that can be conducted at the biotechnology laboratories include:
• molecular microbiology (rapid disease detection and diagnosis)
• molecular endocrinology and genetics (growth enhancement and genetic characterization of wild stocks)
• algal production (strain improvement in seaweeds and high density production of algae used as food for fish, crustacean, and mollusk larvae)
• fish feed technology (nutrient enhancement and development of low-polluting diets)
Why collaborate with us?
• We have the facilities to do studies in tanks, ponds, and cages. We also have state-of-the-art biotechnology laboratories.
• We have multidisciplinary teams, and we have the track record for research (see table).
