Bicol Eyes Tilapia Production for Export Market

PILI, Camarines Sur, Nov. 8 (PNA) -- Bicol is taking the challenge of producing tilapia for both the domestic and export markets.

Local fishery authorities say there is a big area for growth in the production in Bicol of both the small-sized tilapia which is a hit in the local market and the big-sized that is consistently gaining popularity abroad.

The region had vast freshwater resources that are highly suitable for large-scale production. Among these are the Bato and Buhi Lakes in Camarines Sur, Danao Lake in Polangui, Albay, Bulusan Lake in Sorsogon and several other smaller sites sporadically distributed among the six provinces of the region.

All in all, the region’s inland water resources capable of tilapia production are measured at 246,063 hectares of swamplands, 253,854 hectares of brackish water fishponds, 200,000 hectares of lakes, 31,000 hectares of rivers and 19,000 hectares of reservoir, according to data obtained from the Bureau of fisheries and Aquatic Resources (BFAR) regional office here.

For the domestic market, stepping up production of the presently popular small-sized tilapia (scientific name: Tilapia nituka) varieties called “tilanggit” is necessary and BFAR regional director Dennis del Socorro over the week said they are encouraging local stakeholders to raise more preferably through aquaculture.

The industry for the domestic market is fast expanding as tilapia is now officially considered the Filipino poor man’s fish replacing “galunggong” (roundscad).

To step up tilapia production for the domestic market, Del Socorro said they making available more quality tilapia fingerlings for distribution to aquaculture pond operators in the region. These fingerlings are produced by the BFAR at its Regional Freshwater Fisheries Center (RFFC) in Bula, Camarines Sur.

This facility that sits on a 34-hectare property in Barangay Fabrica, Bula is responsible for the production of 30 million quality tilapia fingerlings in 2010 which were distributed to fishermen, pond operators and local government units under a dispersal program of the 2KR- National Agriculture and Fishery Council (NAFC)-assisted special project of the government.

RFFC, Del Socorro said also functions as the Center for verifying, adopting and techno-demonstration of different freshwater aquaculture technologies developed in national center.

It is equipped, among others with a SCV-Artificial Fish Egg Incubator for intensive tilapia hatchery apart from the refinement of induced spawning of African Catfish and breeding of Giant Freshwater Prawn.
We can produce millions more of fingerlings in this facility for a stepped up tilapia production in Bicol,
Del Socorro said.

The beauty of tilapia fingerling production is the way the tilapia eggs are fertilized which involved certain behavior unique to this freshwater species of fish.

Del Socorro said copulation of tilapia starts with the male breeder ramming its head on the belly of the female breeder until the orange eggs are spurted from the orifice at the bottom pectoral fin.

Then, the female breeder gathers its own eggs in its mouth, and then the male breeder flips and positions its orifice and releases its eggs near the mouth of the female breeder which takes them in into its mouth to fertilize with their own eggs earlier stored near the gills.

After eight to 10 days, the fertilized eggs are regurgitated and the process to maturity from fry to fingerling begins.

This process of life creation intended to bring food for the table goes over and over again in the RFFC where male and female breeders are selectively and periodically mated for the production of millions of fingerlings for dispersal all over the region.

Another unique trait in tilapia is that it can easily switch sexes from male to female and vice versa through hormonal manipulation, depending on the ratio of male and female breeders in the ponds.

Del Socorro said that when the male and female ratio of tilapia raised in RFFC becomes greater for the male population they manipulate them to become female breeders by giving them feeds that increase their female hormones.

On the other hand, for the export market which is keener on big-sized tilapia with enough flesh for fillet processing, Del Socorro said they are adopting the genetically improved Nile tilapia strains to innovate on existing nursery and grow-out culture systems to suit the requirements for large-sized fish and intensive production.

Recent reports from the Department of Science and Technology (DOST)-funded program “Innovative approaches to Nile tilapia culture” are pointing out some head start.

Under the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAANRD)-coordinated National Tilapia Research and Development Program (NTRDP), researchers are enhancing local capacity to compete in the world market.

Latest report of the Journal of the American Dietetic Association said that in the United States (US), tilapia has shown the biggest gains in popularity among seafood.

This trend is expected to continue as consumption increased from 1.5 million tons in 2003 to 2.5 million tons in 2010.

Del Socorro said Americans and Europeans have the passion – and taste – for tilapia since they consider it as “white meat,” a health food low in cholesterol and fat. Also, European chefs have a preference for its firm meat.

And because of its large demand in the world market, tilapia commands a high price as in the US.

The DOST-funded program has produced pro-biotics from fermented leaves of red creole onions and shallots, locally known as “sibuyas Tagalog” which when added to feeds of tilapia, improved the growth of tilapia over the 30-day feeding trial.

It has also established the effect of sex reversal using alpha-methyl testosterone, a steroid on improving fish growth.

The research is also looking at plant-based substances from the pine pollen as alternative growth stimulant and agent for sex inversion for tilapia.

Del Socorro said Nile tilapia (Oreochromis niloticus) is the appropriate variety to produce in Bicol for the world market. It is a species of high economic value and is widely introduced outside its natural range. (PNA) LAP/DOC/CBD/

Catanduanes Forest in German-Funded DENR Project

The Catanduanes Watershed Forest Reserve (CWFR) is among the 60 protected areas around the country that are covered by a German-funded environmental project aimed at improving the management of the Philippines’ natural resources. CENRO officer-in-charge Luvimindo Chioco recently told the Tribune that the Protected Area Management Enhancement (PAME) project is being implemented by the Department of Environment and Natural Resources (DENR), under a grant from the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. The funding was coursed through the German Society for International Cooperation (GIZ). The P450 million (€9 million) project is being carried out nationwide until March 2017 to ensure proper management of 60 existing protected areas by improving the technical competencies and capacities of staff of the DENR’s Protected Area and Wildlife Bureau. The PAME project will also see the establishment of at least 100 new terrestrial and mari…

Catanduanes Watershed Forest Reserve

Site description: Catanduanes is an island of 182,300 ha which lies about 10 km off the tip of the Caramoan Peninsula in southern Luzon. The terrain on the island is hilly, particularly in the central portion, but the highest point only reaches just over 800 m. The substantial forests which remain in central Catanduanes are therefore all lowland dipterocarp in type, and are the largest remaining forest block in the whole of the Bicol Region. Forest is found above 490 m, and is estimated to cover a total of about 69,770 ha. It includes considerable areas of old growth dipterocarp forest (reported in 1997 to cover 5,876 ha), and closed-canopy forest in areas that show evidence of having been logged. These forest areas are the source of water for Catanduanes Province. One hydropower project is currently operational, that supplies power to urban areas of the island. The forest areas was proclaimed as a Watershed Reserve in 1987 because of these important function, the whole area is sta…

Japanese Retirement Village in the Philippines

The Philippines is being eyed as a prime medical, health care and retirement destination for Japanese. According to studies, one out of four people in Japan will be aged 65 by 2020, from one out of six in 2000. Now is the best time to set up the retirement village for Japanese as baby boomers will start retiring in 2007. Several notable Japanese companies have already initiated building medical and retirement havens in the Philippines. These include Sanyo Emeritus Co. Ltd., a joint venture between Sanyo Electric and Emeritus Corp. of Seattle, which provides "assisted living" services in the US and Canada; as well as Tokushukai Medical Corp., Japan's largest hospital chain, which is putting up a $100 million, 1000-bed hospital in the Philippines, targeting elderly Japanese citizens. The Philippines is highly regarded because of its mild climate enjoyed by Japanese, its close proximity to Japan, the high quality of the Philippines' healthcare workforce, and the sign…

Pantomina Lyrics And Music

Pantomina is Spanish for pantomime, movements imitating the courtship movements of the rooster and the hen.
Ang mga babaye
Kung mayo pa nin agom
Maugay nin aga maugay nin hapon
Alagad kung sinda igua na nin agom
Maugay Octobre, Disyembreng sunudon.

Ica palan, Nenang ang pinagsasabi
Magayon na burac sa lugar na ini
Magayon ang tindog malinig ang pisngi
Arin pa daw ang puso ang dai mawili.

Can ica sadit pa sadit pa man aco
Si satuyang cawat magkudot-kudotan
Kinudot mo aco kinudot ta ca man
Sabi mo sa saco luhayluhaya man.

Ang mga lalake
Hudyan sisaboot
Ang pinagsasabing ngarang pagcamoot
Kundi ang babayeng iyo minahilod
Akong minahiling can mga pangguyod.

Philippine Mining Act of 1995

With the recent issue of magnetite ore mining overwhemingly opposed by residents in the town of Bagamanoc and recently moved the mining site off the coast of Panganiban (Payo), I am compelled to post this Mining Act to serve as reference. "Republic Act No. 7942 or the Philippine Mining Act of 1995 (“Act”) is the governing law that regulates mineral resources development in the country. One of the primary objectives of this act is to revitalize the ailing Philippine mining industry by providing fiscal reforms and incentives and maintaining a viable inventory of mineral reserves to sustain the industry through the infusion of fresh capital through direct investments to finance mineral exploration and/or development activities. The original implementing rules and regulations of the Act was prepared in 1995, and was revised in 1996 under DENR Administrative Order 96 – 40, the revised implementing rules and regulations (RIRR).

Collectively, the Act and its RIRR take into considerat…
