- The National Fisheries Research and Development Institute (NFRDI) is an attached agency of the Department of Agriculture (DA) tasked to conduct research and development (R&D) for fisheries. NFRDI was established in recognition of the critical role of fisheries R&D in developing, managing, conserving, and protecting the country’s aquatic resources.
- The Bureau of Fisheries and Aquatic Resources (BFAR) is the government agency responsible for the development, improvement, management and conservation of the country’s fisheries and aquatic resources. It was reconstituted as a line bureau by virtue of Republic Act No. 8550 (Philippine Fisheries Code of 1998).
- The Southeast Asian Fisheries Development Center (SEAFDEC) is an autonomous inter-governmental body established in 1967. The mission of SEAFDEC considered and adopted by the Special Meeting of the SEAFDEC Council 2017 is “To promote and facilitate concerted actions among the Member Countries to ensure the sustainability of fisheries and aquaculture in Southeast Asia.”
- The Food and Agriculture Organization (FAO) Philippines is the Philippine office of the United Nations' specialized agency dedicated to eradicating hunger and promoting sustainable agriculture. Operating within the country since 1978, FAO Philippines collaborates with the Philippine government, local communities, and international partners to address the nation's agricultural challenges.

Breeding and culture of fighting fish
(National Fisheries Research and Development Institute, 2025) Department of Agriculture - National Fisheries Research and Development Institute
Fighting fish (Betta splendens), also known as Siamese fighting fish, belong to the gourami family. Native to Southeast Asia, they build bubble nests for spawning and sexually mature in about six months. Females produce 300–1,000 eggs every 3–4 weeks. Males are aggressive and must be kept separately. Breeding involves courtship, egg fertilization, and fry rearing with infusoria and Artemia. Popular varieties include half-moon, crown tail, delta, super delta, and veil tail. Their brilliant colors and unique fin shapes make them highly sought-after ornamental fish.
Breeding and culture of livebearers
(National Fisheries Research and Development Institute, 2025) Department of Agriculture - National Fisheries Research and Development Institute
Livebearers, including guppy, molly, platy, and swordtail, are ornamental fishes that give birth to live young. Originating from South America, they mature in 1–3 months and produce 10–100 fry per brood. Males have modified fins for reproduction, while females give birth at regular intervals. Culture involves small tanks or backyard systems, with fry fed natural or artificial feeds. Hardy and non-aggressive, livebearers are popular beginner’s fish. Their ease of breeding and colorful strains provide opportunities for small-scale aquaculture and hobbyist markets.
Maliputo seed production
(National Fisheries Research and Development Institute, 2025) Department of Agriculture - National Fisheries Research and Development Institute
Maliputo (Caranx ignobilis), also called giant trevally, is a highly prized food fish that can grow up to 80 kg. Seed production involves broodstock selection, hormone injection, egg collection, incubation, and larval rearing. Fertilized eggs hatch within 17 hours, and larvae reach juvenile stage after 30 days. Spawning occurs from April to December, with females producing large numbers of eggs. The program initiated by NFRDI-FRDC ensures sustainable supply, reducing reliance on wild catch and supporting aquaculture of this high-value species.
Breeding and culture of angel fish
(National Fisheries Research and Development Institute, 2025) Department of Agriculture - National Fisheries Research and Development Institute
Angelfish (Pterophyllum spp.) are among the most beautiful tropical fish, native to the Amazon Basin in South America. They are egg-depositors producing 500–1,000 eggs per spawning and reach sexual maturity in 6–12 months. Culture involves paired breeding, egg attachment to substrates, and rearing fry with Artemia before transfer to grow-out tanks. They thrive in soft, slightly acidic, warm water and are voracious feeders. Angelfish varieties have been developed through genetic enhancement and environmental influences, making them valuable in ornamental aquaculture.
Grow-out culture of maliputo in cages
(National Fisheries Research and Development Institute, 2025) Department of Agriculture - National Fisheries Research and Development Institute
Maliputo (Caranx ignobilis), known as the pride of Taal Lake, is the largest among the Caranx genus and the fifth largest of the Carangidae family. It is a migratory, predatory species thriving in freshwater, brackish, and marine waters. Culture in net cages involves stocking 2,000 fingerlings per cage, feeding with trash fish, and harvesting at 6–9 months when fish reach 500–800 g. With a high market price and survival rate of 70–80%, maliputo offers strong potential for commercial aquaculture.
