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]

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.
