Why grouper culture?

  • A high-value species with great demand in the local and export markets
  • With prudent pond management, grouper is easier to culture than shrimp, without the attendant disease problems
  • Wild and captive grouper broodstock spawn year round, hence, fry are available anytime of the year
  • The technology of cage culture is relatively cheap and easy to run
  • Culture can be done in ponds or cages

Marine pond culture 

Preparing ponds for grouper is similar to milkfish and shrimp. At the start of culture, grouper fry need to be nursed first and must be regularly sorted and size-graded. [read more]

Marine cage culture 

Grouper can be raised in a 4- to 12-compartment cage as one unit. There are nursery (small mesh is used in the cage)  and grow-out (larger mesh) phases. Grouper need to be sorted and size-graded every week. [read more]

Marine cage culture

• Bobby Sanson farm, Negros Occidental (1996)
• Brgy Dapdap, Tangalan LGU, Aklan (1999)

The project “Poverty alleviation through aquaculture”
started in 2004 and was funded by the Australian Agency for International Development. Twenty units of 5 x 5 x 3 m fish cages and a floating technician’s quarter were constructed. Two trainees from MACABATA-ARM were trained on-site

From 1989 to the present, SEAFDEC Aquaculture Department has made strides in grouper aquaculture, at first breeding the fish in floating marine cages and in concrete tanks then completing the grouper life cycle in captivity in 1994. These breeding trials went hand-in-hand with the development of hatchery technology. Feed formulation for carnivorous fishes like seabass (and grouper) was likewise worked out, and published in a manual in 1994. Two years later, AQD started work on the verification and demonstration of grouper grow-out culture in brackishwater ponds and in floating net cages. Extension manuals on these experiences were published in 1998 and 2000. AQD had also incorporated grouper in its training courses on marine fish hatchery and on sustainable aquaculture. 

In 1999, SEAFDEC/AQD joined the collaborative APEC (Asia-Pacific Economic Cooperation) grouper research and development network, and published two years later a definitive grouper culture illustrated book whose original English version was translated to four Southeast Asian languages including Filipino. At the same time, AQD started verification trials of grouper culture in netcages and used fry / fingerlings produced at its marine fish hatcheries. [The working technology for grouper hatchery was worked out earlier, in 1994, when AQD completed the life cycle of grouper in captivity.] The beneficiaries of the field trials were fisherfolk cooperatives backed by their local government units.

Two more farmer-friendly manuals were published in 1998 and 2000. And, because disease was a big concern, AQD gathered together information on grouper health management into a book in 2004 after much research funded by the Government of Japan Trust Fund.

      Magandang araw Jaypee! Pasensya na at ngayon lang namin nasagot ang katanungan mo tungkol sa red grouper culture. Wala kaming manual on red grouper culture- in cages ba ito? Pero mayroon kaming flyers sa ibang uri ng grouper. Ito ang orange-spotted grouper at tiger grouper, na inaalagaan namin dito sa SEAFDEC Aquaculture Dept. Pwede mong madownload ang mga flyers namin na ito sa aming website ( I-click mo lang ang free downloads. Sa tingin ko, pareho lang ang prinsipyo ng pag-aalaga ng red suno sa karaniwang grouper. Base sa mga nababasa ko sa mga libro at scientific journals, ang pag-aalaga ng red suno sa cages hanggang magharvest ay umaabot ng hanggang isang taon, depende sa initial size ng pagstock mo sa cages. Kung medyo malalaki na ang inistock mo, syempre, mabilis mo rin syang mahaharvest.

      Kung gusto nyong magkaroon ng karagdagang kaalaman tungkol sa pagsesemilya ng grouper(grouper hatchery), pwede kayong magtraining dito sa SEAFDEC Aquaculture Dept., Tigbauan, Iloilo.
      Naway nakapagbigay ako sa iyo ng kaunting kaalaman tungkol sa grouper culture. Hanggang sa muli.

  8. Dear Sir/Maam,

    I am writing to you to inquire regarding the fingerlings for epinephelus coioides species of grouper.
    Do you produce fingerlings for this kind of grouper species?

    By way, I am Ferjess Lamoste, Cage Farm Manager in ASMAK B.S.C. Company in Bahrain. And my company would like to engage in culturing this species of grouper. And we are looking for a hatchery that produces the fingerlings.

    Sincerely yours,

      Dear Ferjess,
      Greetings from SEAFDEC Aquaculture Dept., Tigbauan Main Station, Tigbauan, Iloilo!
      This refers to your query on E. coioides fingerlings dated 16 Feb. 2014.
      Yes, we produce/sell E. coioides fry/fingerlings on a first come, first serve basis, but only in limited quantities. For booking, please contact our fish hatchery manager, Ofelia Reyes at cel.nos.: 09182477261. To ensure a more reliable supply of this fingerlings, I suggest that you or any of your staff attend a 37-days regular training course on marine fish hatchery. This course covers topics on broodstock management, larval rearing of groupers (E. coioides and E. fusc0guttatus), sea bass (L. calcarifer), mangrove red snapper (L. argentimaculatus), siganid (S. guttatus), milkfish and pompano (Trachinotus blochii), natural food culture, cage and pond culture of high-value species, among others. Alternatively, you can undergo a specialized training on grouper hatchery alone. Please email me at for details.

      Thank you for your interest in the activities of SEAFDEC Aquaculture Dept. Hope to hear from you soon. Good day!
