  The Philippine aquaculture industry 

  Camacho, Arsenio S.; Macalincag-Lagua, Natividad (Aquaculture Department, Southeast Asian Fisheries Development Center, 1988)

  The aquaculture sector of the Philippine fishing industry registered the highest growth rate of 12.5% in 1977-1986. The contribution of aquaculture to the total fish production was equivalent to 24% in 1986 compared to only 85 in the early 1970's. In terms of quantity, the mariculture subsector registered the highest growth rate of 10.2% in 1982-1986, whereas in terms of value the brackishwater fishpond subsector showed the highest growth rate of 33%. Meanwhile, freshwater aquaculture production exhibited a negative growth rate due to reduction of activities in Laguna de Bay and the slow expansion in hectarage of the commercial freshwater fishponds. Research by several agencies concentrated heavily on the culture of milkfish (Chanos chanos), tilapia (Oreochromis niloticus), Chinese carps (Aristichthys nobilis and Hypophthalmichthys molitrix), tiger prawn (Penaeus monodon), and sea bass (Lates calcarifer). Innovations in seaweed, oyster, and mussel farming are also discussed. Research directions are presented to assure an ecologically sustainable growth in aquaculture with emphasis on countryside development.

  Aquaculture in the Philippines 

  Aypa, Simeona M. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)

  Aquaculture is regarded as the most promising source of protein food in the years ahead. Milkfish and Nile tilapia are the major fishes now produced but groupers, sea bass, rabbitfish, red snappers, carps, and catfishes are grown by some farmers. The tiger shrimp is still the most important cultured crustacean, but white shrimps and mudcrabs also have great potential. Oysters and mussels are produced in considerable amounts. Mariculture of the seaweed Eucheuma is now a well established industry, and the pond culture of Gracilaria for agar extraction is beginning to take off.

  Nursery and grow-out operation and management of milkfish 

  Bombeo-Tuburan, Isidra.; Gerochi, Dante D. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1988)

  This paper reviews the results of studies on the pond culture of milkfish Chanos chanos Forsskal at the SEAFDEC Leganes Brackishwater Station, Leganes, Iloilo since its establishment in 1973. Substantial contribution on the nursery system includes increased stocking density and survival through the use of nylon substrates, supplemental feeding with rice bran, the use of hatchery-reared and stunted fingerlings as alternative sources of stocks, and improvements in the acclimation process. Studies on monoculture and polyculture in grow-out ponds investigated the use of stunted fingerlings, kitchen or algal nursery ponds, stock manipulation techniques, increased stocking density using the plankton method, method frequency and quantity of fertilization, modular pond culture system, and initial findings on fish diseases. Constraints setting back increased production in the Philippines are discussed.
