PCAARRD to honor Agri-Aqua R&D’s best

The Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (PCAARRD-DOST) will recognize the men and women as well as the institutions that have truly contributed in uplifting the state of agricultural R&D in this country through its Research and Development Exhibits and Awarding Ceremonies.

The event will be held at Sofitel Philippine Plaza Manila, Roxas Blvd., Pasay City on November 8, 2013. Prestigious awards will be conferred on deserving individuals and institutions who have helped in shaping up the country’s agricultural landscape. These awards include the Best R&D Papers; Pantas for outstanding scientists/researchers and research administrators; Tanglaw for outstanding research institutions; Ugnay for the best R&D Consortium; Elvira Tan Memorial Award for Outstanding Fisheries Publication; and the Professional Media Award for outstanding contributions of the regional media practitioners in technology diffusion.

With the theme PCAARRD: Kaagapay sa Pag-unlad ng Industrya ng Sakahan at Pangisdaan, the occasion will showcase PCAARRD’s efforts and that of its partners not only in generating productive and worthwhile technologies but also in pushing the commercialization of regional S&T-based agricultural products.

Exhibits, which will simultaneously be held during the awarding rites, will feature agricultural commodities being supported by the Council under its Industry Strategic S&T Plans  (ISPs). These include cacao, organic coffee, papaya, rice, rubber, abaca, mango, protein enrichment of copra meal (PECM), algal paste, mudcrab, blue swimming crab, oyster, and mussel.

Designed for the development of the various industries integral in the agriculture, aquatic, and natural resources sectors (AANR) sectors; the ISPs describe the targets for each industry and pinpoints the aspects of the industry where S&T will make a difference.

The ISPs contribute to poverty alleviation and inclusive growth through food security, countryside development, developing competitive industries, biodiversity conservation and sustainable development, and climate change mitigation/adaptation and disaster risk reduction.

Dr. Arsenio M. Balisacan, Socio-economic Planning Secretary and Director General of the National Economic and Development Authority (NEDA) will be the event’s keynote speaker. Balisacan’s keynoting the event is expected to accentuate the mutuality in the roles of NEDA and PCAARRD in terms of the formulation of national plans and policies for the agriculture and natural resources sectors, being among NEDA’s important roles.

A graduate of BS Agriculture and Agricultural Economics for his MS, enriched by his research interest in the field of agricultural economics, Balisacan proves to be a fine choice for the task of staging the vital link between agriculture and agriculture-based industries, and at the same time inspiring even more laudable accomplishments in agricultural R&D during the event.

Balisacan’s notable publications and discussion papers on agricultural growth and development include his “Policy reforms and agricultural development in the Philippines;” “Agricultural growth, landlessness, off-farm employment, and rural poverty in the Philippines;” and “Public choice of economic policy: the growth of agricultural protection.”  (Ricardo R.

Microalgae can be a potential feed for aquaculture species

 Microalgae, which are sources of natural aquatic products, are now gaining attention as an ideal potential feed for aquaculture purposes.

At the University of the Philippines Visayas (UPV), the program on the development of algal paste from microalgae under the National Aquafeeds R&D Program is currently being funded by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and the Development (PCAARRD) and Department of Science and Technology (DOST).

The program studies intensively three brackishwater microalgal species,namely, Tetraselmis sp., Nannochloropsis sp., and Chaetoceros calcitrans. These species, which are used in the mass production of algal paste, are cultured by batch in the laboratory and are continuously monitored for quality control.

Microalgae are small unicellular plants found in marine, freshwater, and brackishwater habitats. They are considered as one of the most important aquatic organisms for its many uses in various fields. They are also fast-growing plants, with their doubling time measured in hours.

For aquaculture, microalgae concentrates are used as feed for small zooplankters (rotifers, etc.) which in turn are fed to fish and shrimp larvae. These are produced commercially from closely controlled laboratory methods to less predictable methods in outdoor tanks or ponds. Algal mass production is dependent on algal strains, weather, and culture techniques.

Aside from aquaculture, microalgae are also produced commercially for high-value nutritional products and wastewater treatment applications.

For its culture, algae are harvested and prepared using a chemical flocculant once it has reached its peak density. Concentrated cells collected are transferred in another container for another settling process and filtered until pastes are formed.

The advantage of using algal paste is that it can be used as an alternative to on-site algal culture, especially when rations of live microalgae are insufficient. Also, microalgae paste can be kept under refrigerated condition without sacrificing the nutritional quality for several months.

Microalgal paste is an instant feed that can be applied easily for aquaculture purposes anytime for fish stock. Commercial algal paste costs US$50 to US$150 per liter paste, depending on the species.

With microalgal paste, worries on phytoplankton culture and maintenance can be reduced, if not eliminated. Algal paste as an alternative for live microalgae production will surely benefit the local industries, particularly those engaged in milkfish, shrimp, and tilapia hatcheries by lowering their production and labor cost. Microalgal pastes are now being produced at the Institute of Aquaculture, UPV-College of Fisheries and Ocean Sciences in Miag-ao, Iloilo.

The PCAARRD-DOST program, which is on its second year of implementation, is currently conducting experiments to further verify the pastes’ nutritional quality and shelf life. (Soledad S. Garibay, Institute of Aquaculture, UPV-College of Fisheries and Ocean Sciences, S&T Media Service)

Microalgae maaring pakain pang aquaculture -PCAARRD-DOST

Nakikilala ngayon ang Microalgae, pinagmulan ng maraming natural aquatic products na maaring maging potential feed pang aquaculture purposes. Sa University of the Philippines Visayas (UPV), sa kanilang programang development of algal paste from microalgae sa ilalim ng National Aquafeeds R&D Program na kasalukuyang pinopondohan ng Philippine Council for Agriculture, Aquatic and Natural Resources Research and the Development (PCAARRD) at ng Department of Science and Technology (DOST).

Sa nasabing programa nakatuon sila sa tatlong brackishwater microalgal species, kagaya ng, Tetraselmis sp., Nannochloropsis sp., at Chaetoceros calcitrans. Ang mga ito ay magagamit sa mass production of algal paste, na kinu culture by batch sa mga laboratory at minomonitor para sa kalidad.

Ang mga Microalgae ay maliliit na unicellular plants na nakikita sa  marine, freshwater, at brackishwater habitats. Itinuturing silang isa sa mga mahalagang aquatic organisms dahil na rin sa kanilang mga gamit sa ibat ibang larangan ng industriya, mabilis din silang lumaki at ang haba ng pagdoble ng kanilang buhay ay nasusukat lamang sa oras.

Sa aquaculture, microalgae concentrates ay ginagamit bilang pakain sa mga maliliit na zooplankters (rotifers, etc.) na ipinakakain rin sa isda at shrimp larvae. Ang mga produktong ito ay kinokontrol sa laboratory dahil hindi maari sa mga ponds, ang Algal mass production ay dependent sa mga algal strains, weather, at culture techniques.

Bukod sa aquaculture, ipino prodyus din pang komersyal ang microalgae bilang high-value nutritional products at sa wastewater treatment applications. Pang culture nito, hina harvest ang mga algae at inihahanda upang gamitin bilang chemical flocculant pag natamo na nito ang tamang bigat.

Kinukuha ang mga concentrated cells at inililipat sa isang lalagyan para s susunod na proseso at pagsala hanggang mabuo ang pormang pastes nito. Ang benstahe sa paggamit ng  algal paste ay maari itong magamit bilang alternatibo sa on-site algal culture, lalo kung walang makuhang buhay na microalgae o kung kulang.

Bukod pa rito, ang microalgae paste ay maaring itabi sa loob ng refrigerated condition sa loob ng ilang buwan na hindi maisasawalambahala ang nutrisyunal na kalidad nito. Ang Microalgal paste bilang isang instant feed na maaring i-apply pang aquaculture purposes sa kahit anong panahon bilang fish stock. Ang pang Commercial na algal paste ay nagkaka halaga ng US$50 hanggang US$150 kada litro ng paste, depende sa species.

Kung may microalgal paste,ang pangamba ukol sa mga phytoplankton culture at maintenance ay mababawasan o tuluyang maia alis na.  Ang  Algal paste ay isang alternatibo sa buhay na microalgae production na tiyak na magbebenepisyo ang industriyang local lalo ang mga nasa bangus, hipon at tilapia hatcheries kung saan mapapababa ang halaga ng produksyon at paggawa. Ginagawa na ang Microalgal pastes ngayon sa Institute of Aquaculture, UPV-College of Fisheries and Ocean Sciences sa Miag-ao, Iloilo.

ang PCAARRD-DOST program na ito ay nasa ikalawng taon anng implimentasyon at kasalukuyang nagsasagawa ng mga eksperimento upang lalo pang matiyak ang kalidad pang nutrisyon at ng shelf life. ( buhat sa mga detalyeng galing kay Soledad S.

Aquaponics isang praktikal na pangingisda sa kalunsuran

MARAMI na ang naninirahan sa kalunsuran. Hindi naman sa unti-unti nang nililisan ang ating mga kanayunan upang maghanap ng swerte, kundi patungo na sa pag asenso ang bayan.

Kaya naman marami nang mga nakapag iisip ng mga alternatibong paraan upang ang limitadong likas na kayamanan ay maparami at makapagpakain ng maraming tao.

Sa nakaraang National Science and Technology Week Expo 2013 ay nagpakita ang ilang teknolohiyang tunay na maaring maging bintana sa hinaharap ng matalinong paraan ng agrikultura.

Ang paraang ng Aquaponics ay maaring ihalintulad sa ibang makabagong paraan ng pagsasaka ngayon sa mga mauunlad na bansa. Hindi ito gumagamit ng lupa at pataba bagkus ay nakapag papatubo ng mga gulay at prutas sa pamamagitan lamang ng pagpa paikot o resiklo ng tubig.

Ang tubig namang ginagamit ay may lamang isda, kung ano man ang maibigang isdang tabang na alagaan ng magsasakang mag a aquaponics ay depende sa kanyang nais. Pinipiling alagaan ay ang bangus, tilapia (anu mang uri nito) o mga ornamental fish na maganda sa mata.

Ang dumi ng nasabing mga isdang inaalagaan ay magsisilbing pataba sa mga halamang nakasawsaw sa pond gaya ng kangkong gayundin sa nareresiklong tubig na bumababa sa mga hose na bumabagsak naman sa mga gulay o prutas gaya ng kamatis, lettuce atbp na pinatutubo ng magsasaka.

Isa sa isinusulong ng Philippine Council for Agriculture, Aquatic and natural Resources Research and Development (PCAARRD) ng Department of Science and Technology (DOST) ang Aquaponics dahil di lamang ito pagtatanim bagkus ito pa ay pag a aqua culture.

Ang Pilipinas ay kapuluan at marami sa mga mamamayan natin sa baybaying dagat ay nabubuhay sa mga biyaya ng tubig, agricultural rin tayo dahil malaking bilang ng pambansang kita ay sa sector ng agrikultura.

Ito ang bahagi ng kanilang presentasyon sa nakaraang National Science and Technology Week (EXPO Science 2013) na ginanap sa SMX MOA nitong nakaraang linggo kung saan nag present ng aquaponics technology si Dr. Sace ng Central Luzon State University.

Kabilang sina Dr. Patricio Faylong, Executive Director ng PCAARRD at DOST Sec. Mario Montejo sa mga nagbigay ng makabuluhang pananalita kasama ang mga magsasaka, entreprenyur, mga mamamahayag kabilang ang pahayagang ito (www.diaryongtagalog.net) sa mga nakibahagi.

Sa patuloy na pag sulong ng ating bansa, magma migrate na karamihan sa kalunsuran, magiging maunlad ang kanayunan di dahil nilayasan na sila ng tradisyunal na paraan ng pagsasaka kundi dahil matitiyak na ang seguridad sa pagkain ng bansa, sapat na suplay ang maibibigay dahil di lang sa kanayunan kundi pati sa kalunsuran ay maaring magsaka at magkaroon ng pangisdaan sa pamamagitan ng teknolohiyang aquaponics.
